### Terms and Conditions for use, reproduction, and distribution
|
||||
|
||||
#### 1. Definitions
|
||||
|

|
||||
permissions granted by this License.
|
||||
|
||||
“Source” form shall mean the preferred form for making modifications, including

||||
but not limited to software source code, documentation source, and configuration
|
||||
files.
|
||||
|
||||
“Object” form shall mean any form resulting from mechanical transformation or
|
||||
translation of a Source form, including but not limited to compiled object code,
|
||||
generated documentation, and conversions to other media types.
|
||||
|
||||
“Work” shall mean the work of authorship, whether in Source or Object form, made
|
||||
available under the License, as indicated by a copyright notice that is included
|
||||
in or attached to the work (an example is provided in the Appendix below).
|
||||
|
||||
“Derivative Works” shall mean any work, whether in Source or Object form, that
|
||||
is based on (or derived from) the Work and for which the editorial revisions,
|
||||
annotations, elaborations, or other modifications represent, as a whole, an
|
||||
original work of authorship. For the purposes of this License, Derivative Works
|
||||
shall not include works that remain separable from, or merely link (or bind by
|
||||
name) to the interfaces of, the Work and Derivative Works thereof.
|
||||
|
||||
“Contribution” shall mean any work of authorship, including the original version
|
||||
of the Work and any modifications or additions to that Work or Derivative Works
|
||||
thereof, that is intentionally submitted to Licensor for inclusion in the Work
|
||||
by the copyright owner or by an individual or Legal Entity authorized to submit
|
||||
on behalf of the copyright owner. For the purposes of this definition,
|
||||
“submitted” means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems, and
|
||||
issue tracking systems that are managed by, or on behalf of, the Licensor for
|
||||
the purpose of discussing and improving the Work, but excluding communication
|
||||
that is conspicuously marked or otherwise designated in writing by the copyright
|
||||
owner as “Not a Contribution.”
|
||||
|
||||
“Contributor” shall mean Licensor and any individual or Legal Entity on behalf
|
||||
of whom a Contribution has been received by Licensor and subsequently
|
||||
incorporated within the Work.
|
||||
|
||||
#### 2. Grant of Copyright License
|
||||
|
||||
Subject to the terms and conditions of this License, each Contributor hereby
|
||||
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
|
||||
irrevocable copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the Work and such
|
||||
Derivative Works in Source or Object form.
|
||||
|
||||
#### 3. Grant of Patent License
|
||||
|
||||
Subject to the terms and conditions of this License, each Contributor hereby
|
||||
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
|
||||
irrevocable (except as stated in this section) patent license to make, have
|
||||
made, use, offer to sell, sell, import, and otherwise transfer the Work, where
|
||||
such license applies only to those patent claims licensable by such Contributor
|
||||
that are necessarily infringed by their Contribution(s) alone or by combination
|
||||
of their Contribution(s) with the Work to which such Contribution(s) was
|
||||
submitted. If You institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
|
||||
Contribution incorporated within the Work constitutes direct or contributory
|
||||
patent infringement, then any patent licenses granted to You under this License
|
||||
for that Work shall terminate as of the date such litigation is filed.
|
||||
|
||||
#### 4. Redistribution
|
||||
|
||||
You may reproduce and distribute copies of the Work or Derivative Works thereof
|
||||
in any medium, with or without modifications, and in Source or Object form,
|
||||
provided that You meet the following conditions:
|
||||
|
||||
* **(a)** You must give any other recipients of the Work or Derivative Works a copy of
|
||||
this License; and
|
||||
* **(b)** You must cause any modified files to carry prominent notices stating that You
|
||||
changed the files; and
|
||||
* **(c)** You must retain, in the Source form of any Derivative Works that You distribute,
|
||||
all copyright, patent, trademark, and attribution notices from the Source form
|
||||
of the Work, excluding those notices that do not pertain to any part of the
|
||||
Derivative Works; and
|
||||
* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
|
||||
Derivative Works that You distribute must include a readable copy of the
|
||||
attribution notices contained within such NOTICE file, excluding those notices
|
||||
that do not pertain to any part of the Derivative Works, in at least one of the
|
||||
following places: within a NOTICE text file distributed as part of the
|
||||
Derivative Works; within the Source form or documentation, if provided along
|
||||
with the Derivative Works; or, within a display generated by the Derivative
|
||||
Works, if and wherever such third-party notices normally appear. The contents of
|
||||
the NOTICE file are for informational purposes only and do not modify the
|
||||
License. You may add Your own attribution notices within Derivative Works that
|
||||
You distribute, alongside or as an addendum to the NOTICE text from the Work,
|
||||
provided that such additional attribution notices cannot be construed as
|
||||
modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and may provide
|
||||
additional or different license terms and conditions for use, reproduction, or
|
||||
distribution of Your modifications, or for any such Derivative Works as a whole,
|
||||
provided Your use, reproduction, and distribution of the Work otherwise complies
|
||||
with the conditions stated in this License.
|
||||
|
||||
#### 5. Submission of Contributions
|
||||
|
||||
Unless You explicitly state otherwise, any Contribution intentionally submitted
|
||||
for inclusion in the Work by You to the Licensor shall be under the terms and
|
||||
conditions of this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify the terms of
|
||||
any separate license agreement you may have executed with Licensor regarding
|
||||
such Contributions.
|
||||
|
||||
#### 6. Trademarks
|
||||
|
||||
This License does not grant permission to use the trade names, trademarks,
|
||||
service marks, or product names of the Licensor, except as required for
|
||||
reasonable and customary use in describing the origin of the Work and
|
||||
reproducing the content of the NOTICE file.
|
||||
|
||||
#### 7. Disclaimer of Warranty
|
||||
|
||||
Unless required by applicable law or agreed to in writing, Licensor provides the
|
||||
Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
|
||||
including, without limitation, any warranties or conditions of TITLE,
|
||||
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
|
||||
solely responsible for determining the appropriateness of using or
|
||||
redistributing the Work and assume any risks associated with Your exercise of
|
||||
permissions under this License.
|
||||
|
||||
#### 8. Limitation of Liability
|
||||
|
||||
In no event and under no legal theory, whether in tort (including negligence),
|
||||
contract, or otherwise, unless required by applicable law (such as deliberate
|
||||
and grossly negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special, incidental,
|
||||
or consequential damages of any character arising as a result of this License or
|
||||
out of the use or inability to use the Work (including but not limited to
|
||||
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
|
||||
any and all other commercial damages or losses), even if such Contributor has
|
||||
been advised of the possibility of such damages.
|
||||
|
||||
#### 9. Accepting Warranty or Additional Liability
|
||||
|
||||
While redistributing the Work or Derivative Works thereof, You may choose to
|
||||
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
|
||||
other liability obligations and/or rights consistent with this License. However,
|
||||
in accepting such obligations, You may act only on Your own behalf and on Your
|
||||
sole responsibility, not on behalf of any other Contributor, and only if You
|
||||
agree to indemnify, defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason of your
|
||||
accepting any such warranty or additional liability.

||||
is based on (or derived from) the Work and for which the editorial revisions,
|
||||
annotations, elaborations, or other modifications represent, as a whole, an

such license applies only to those patent claims licensable by such Contributor
|
||||
that are necessarily infringed by their Contribution(s) alone or by combination
|
||||
of their Contribution(s) with the Work to which such Contribution(s) was
|
||||
submitted. If You institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
|
||||
Contribution incorporated within the Work constitutes direct or contributory
|
||||
patent infringement, then any patent licenses granted to You under this License
|
||||
for that Work shall terminate as of the date such litigation is filed.
|
||||
|
||||
#### 4. Redistribution
|
||||
|
||||
You may reproduce and distribute copies of the Work or Derivative Works thereof
|
||||
in any medium, with or without modifications, and in Source or Object form,
|
||||
provided that You meet the following conditions:
|
||||
|
||||
* **(a)** You must give any other recipients of the Work or Derivative Works a copy of
|
||||
this License; and
|
||||
* **(b)** You must cause any modified files to carry prominent notices stating that You
|
||||
changed the files; and
|
||||
* **(c)** You must retain, in the Source form of any Derivative Works that You distribute,
|
||||
all copyright, patent, trademark, and attribution notices from the Source form
|
||||
of the Work, excluding those notices that do not pertain to any part of the
|
||||
Derivative Works; and
|
||||
* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
|
||||
Derivative Works that You distribute must include a readable copy of the
|
||||
attribution notices contained within such NOTICE file, excluding those notices
|
||||
that do not pertain to any part of the Derivative Works, in at least one of the
|
||||
following places: within a NOTICE text file distributed as part of the
|
||||
Derivative Works; within the Source form or documentation, if provided along
|
||||
with the Derivative Works; or, within a display generated by the Derivative
|
||||
Works, if and wherever such third-party notices normally appear. The contents of
|
||||
the NOTICE file are for informational purposes only and do not modify the
|
||||
License. You may add Your own attribution notices within Derivative Works that
|
||||
You distribute, alongside or as an addendum to the NOTICE text from the Work,
|
||||
provided that such additional attribution notices cannot be construed as
|
||||
modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and may provide
|
||||
additional or different license terms and conditions for use, reproduction, or
|
||||
distribution of Your modifications, or for any such Derivative Works as a whole,
|
||||
provided Your use, reproduction, and distribution of the Work otherwise complies
|
||||
with the conditions stated in this License.
|
||||
|
||||
#### 5. Submission of Contributions
|
||||
|
||||
Unless You explicitly state otherwise, any Contribution intentionally submitted
|
||||
for inclusion in the Work by You to the Licensor shall be under the terms and
|
||||
conditions of this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify the terms of
|
||||
any separate license agreement you may have executed with Licensor regarding
|
||||
such Contributions.
|
||||
|
||||
#### 6. Trademarks
|
||||
|
||||
This License does not grant permission to use the trade names, trademarks,
|
||||
service marks, or product names of the Licensor, except as required for

||||
reasonable and customary use in describing the origin of the Work and
|
||||
reproducing the content of the NOTICE file.
|
||||
|
||||

||||
Unless required by applicable law or agreed to in writing, Licensor provides the
|
||||
Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
|
||||
including, without limitation, any warranties or conditions of TITLE,
|
||||
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
|
||||
solely responsible for determining the appropriateness of using or
|
||||
redistributing the Work and assume any risks associated with Your exercise of
|
||||
permissions under this License.
|
||||
|
||||
#### 8. Limitation of Liability
|
||||
|
||||
In no event and under no legal theory, whether in tort (including negligence),
|
||||
contract, or otherwise, unless required by applicable law (such as deliberate
|
||||
and grossly negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special, incidental,
|
||||
or consequential damages of any character arising as a result of this License or
|
||||
out of the use or inability to use the Work (including but not limited to
|
||||
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
|
||||
any and all other commercial damages or losses), even if such Contributor has
|
||||
been advised of the possibility of such damages.
|
||||
|
||||
#### 9. Accepting Warranty or Additional Liability
|
||||
|
||||
While redistributing the Work or Derivative Works thereof, You may choose to
|
||||
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
|
||||
other liability obligations and/or rights consistent with this License. However,
|
||||
in accepting such obligations, You may act only on Your own behalf and on Your
|
||||
sole responsibility, not on behalf of any other Contributor, and only if You
|
||||
agree to indemnify, defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason of your
|
||||

# ADS1115 ADC
|
||||
|
||||
A driver for the Texas Instruments `ADS1115` 16-bit I2C ADC, exposed as an ADC controller
|
||||
with the four single-ended inputs AIN0 to AIN3 as channels 0 to 3.
|
||||
|
||||
Each read is a single-shot conversion. The result is returned as a 12-bit value: 0 to 4095
|
||||
covers 0 V to the configured full-scale voltage, negative readings are returned as 0.
|
||||
Written from the TI datasheet (SBAS444).

|
||||
of the Work, excluding those notices that do not pertain to any part of the
|
||||
Derivative Works; and
|
||||
* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
|
||||
Derivative Works that You distribute must include a readable copy of the

||||
distribution of Your modifications, or for any such Derivative Works as a whole,
|
||||
provided Your use, reproduction, and distribution of the Work otherwise complies
|
||||
with the conditions stated in this License.

|
||||
for inclusion in the Work by You to the Licensor shall be under the terms and
|
||||
conditions of this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify the terms of
|
||||
any separate license agreement you may have executed with Licensor regarding
|
||||
such Contributions.
|
||||
|
||||
#### 6. Trademarks
|
||||
|
||||

contract, or otherwise, unless required by applicable law (such as deliberate
|
||||
and grossly negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special, incidental,
|
||||
or consequential damages of any character arising as a result of this License or
|
||||
out of the use or inability to use the Work (including but not limited to
|
||||
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
|
||||
any and all other commercial damages or losses), even if such Contributor has
|
||||
been advised of the possibility of such damages.
|
||||
|
||||
#### 9. Accepting Warranty or Additional Liability
|
||||
|
||||
While redistributing the Work or Derivative Works thereof, You may choose to

in accepting such obligations, You may act only on Your own behalf and on Your
|
||||
sole responsibility, not on behalf of any other Contributor, and only if You
|
||||
agree to indemnify, defend, and hold each Contributor harmless for any liability

# ES7243E microphone ADC
|
||||
|
||||
A driver for the `ES7243E` stereo audio ADC by Everest Semiconductor, wired as an
|
||||
input-only `AUDIO_CODEC_TYPE` device. The I2C bus is the device's parent, the I2S
|
||||
controller carrying the audio data is referenced via a devicetree phandle. The ADC
|
||||
runs as I2S slave with MCLK from the pad (MCLK = 256 x sample rate).
|
||||
|
||||
Wraps Espressif's `esp_codec_dev` ES7243E implementation.

such license applies only to those patent claims licensable by such Contributor
|
||||
that are necessarily infringed by their Contribution(s) alone or by combination
|
||||
of their Contribution(s) with the Work to which such Contribution(s) was
|
||||
submitted. If You institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
|
||||
Contribution incorporated within the Work constitutes direct or contributory
|
||||
patent infringement, then any patent licenses granted to You under this License
|
||||
for that Work shall terminate as of the date such litigation is filed.
|
||||
|
||||
#### 4. Redistribution
|
||||
|
||||
You may reproduce and distribute copies of the Work or Derivative Works thereof
|
||||
in any medium, with or without modifications, and in Source or Object form,
|
||||
provided that You meet the following conditions:
|
||||
|
||||
* **(a)** You must give any other recipients of the Work or Derivative Works a copy of
|
||||
this License; and
|
||||
* **(b)** You must cause any modified files to carry prominent notices stating that You
|
||||
changed the files; and
|
||||
* **(c)** You must retain, in the Source form of any Derivative Works that You distribute,
|
||||
all copyright, patent, trademark, and attribution notices from the Source form
|
||||
of the Work, excluding those notices that do not pertain to any part of the
|
||||
Derivative Works; and
|
||||
* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
|
||||
Derivative Works that You distribute must include a readable copy of the
|
||||
attribution notices contained within such NOTICE file, excluding those notices
|
||||
that do not pertain to any part of the Derivative Works, in at least one of the
|
||||
following places: within a NOTICE text file distributed as part of the
|
||||
Derivative Works; within the Source form or documentation, if provided along
|
||||
with the Derivative Works; or, within a display generated by the Derivative
|
||||
Works, if and wherever such third-party notices normally appear. The contents of
|
||||
the NOTICE file are for informational purposes only and do not modify the
|
||||
License. You may add Your own attribution notices within Derivative Works that
|
||||
You distribute, alongside or as an addendum to the NOTICE text from the Work,
|
||||
provided that such additional attribution notices cannot be construed as
|
||||
modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and may provide
|
||||
additional or different license terms and conditions for use, reproduction, or
|
||||
distribution of Your modifications, or for any such Derivative Works as a whole,
|
||||
provided Your use, reproduction, and distribution of the Work otherwise complies
|
||||
with the conditions stated in this License.
|
||||
|
||||
#### 5. Submission of Contributions
|
||||
|
||||
Unless You explicitly state otherwise, any Contribution intentionally submitted
|
||||
for inclusion in the Work by You to the Licensor shall be under the terms and
|
||||
conditions of this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify the terms of
|
||||
any separate license agreement you may have executed with Licensor regarding
|
||||
such Contributions.
|
||||
|
||||
#### 6. Trademarks
|
||||
|
||||
This License does not grant permission to use the trade names, trademarks,
|
||||
service marks, or product names of the Licensor, except as required for
|
||||
reasonable and customary use in describing the origin of the Work and
|
||||
reproducing the content of the NOTICE file.
|
||||
|
||||
#### 7. Disclaimer of Warranty
|
||||
|
||||
Unless required by applicable law or agreed to in writing, Licensor provides the
|
||||
Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
|
||||
including, without limitation, any warranties or conditions of TITLE,
|
||||
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
|
||||
solely responsible for determining the appropriateness of using or
|
||||
redistributing the Work and assume any risks associated with Your exercise of
|
||||
permissions under this License.
|
||||
|
||||
#### 8. Limitation of Liability
|
||||
|
||||
In no event and under no legal theory, whether in tort (including negligence),
|
||||
contract, or otherwise, unless required by applicable law (such as deliberate
|
||||
and grossly negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special, incidental,
|
||||
or consequential damages of any character arising as a result of this License or
|
||||
out of the use or inability to use the Work (including but not limited to
|
||||
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
|
||||
any and all other commercial damages or losses), even if such Contributor has
|
||||
been advised of the possibility of such damages.
|
||||
|
||||
#### 9. Accepting Warranty or Additional Liability
|
||||
|
||||
While redistributing the Work or Derivative Works thereof, You may choose to
|
||||
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
|
||||
other liability obligations and/or rights consistent with this License. However,
|
||||
in accepting such obligations, You may act only on Your own behalf and on Your
|
||||
sole responsibility, not on behalf of any other Contributor, and only if You
|
||||
agree to indemnify, defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason of your
|
||||
accepting any such warranty or additional liability.

|
||||
|
||||
“Derivative Works” shall mean any work, whether in Source or Object form, that
|
||||
is based on (or derived from) the Work and for which the editorial revisions,
|
||||
annotations, elaborations, or other modifications represent, as a whole, an
|
||||
original work of authorship. For the purposes of this License, Derivative Works
|
||||
shall not include works that remain separable from, or merely link (or bind by
|
||||
name) to the interfaces of, the Work and Derivative Works thereof.
|
||||

#### 2. Grant of Copyright License
|
||||
|
||||
Subject to the terms and conditions of this License, each Contributor hereby
|
||||
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
|
||||
irrevocable copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the Work and such
|
||||
Derivative Works in Source or Object form.
|
||||
|
||||
#### 3. Grant of Patent License
|
||||
|
||||
Subject to the terms and conditions of this License, each Contributor hereby
|
||||
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
|
||||
irrevocable (except as stated in this section) patent license to make, have
|
||||
made, use, offer to sell, sell, import, and otherwise transfer the Work, where
|
||||
such license applies only to those patent claims licensable by such Contributor
|
||||
that are necessarily infringed by their Contribution(s) alone or by combination
|
||||
of their Contribution(s) with the Work to which such Contribution(s) was
|
||||
submitted. If You institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
|
||||
Contribution incorporated within the Work constitutes direct or contributory
|
||||
patent infringement, then any patent licenses granted to You under this License
|
||||
for that Work shall terminate as of the date such litigation is filed.
|
||||
|
||||
#### 4. Redistribution
|
||||
|
||||
You may reproduce and distribute copies of the Work or Derivative Works thereof
|
||||
in any medium, with or without modifications, and in Source or Object form,
|
||||
provided that You meet the following conditions:
|
||||
|
||||
* **(a)** You must give any other recipients of the Work or Derivative Works a copy of
|
||||
this License; and
|
||||
* **(b)** You must cause any modified files to carry prominent notices stating that You
|
||||
changed the files; and
|
||||
* **(c)** You must retain, in the Source form of any Derivative Works that You distribute,
|
||||
all copyright, patent, trademark, and attribution notices from the Source form
|
||||
of the Work, excluding those notices that do not pertain to any part of the
|
||||
Derivative Works; and
|
||||
* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
|
||||
Derivative Works that You distribute must include a readable copy of the
|
||||
attribution notices contained within such NOTICE file, excluding those notices
|
||||
that do not pertain to any part of the Derivative Works, in at least one of the
|
||||
following places: within a NOTICE text file distributed as part of the
|
||||
Derivative Works; within the Source form or documentation, if provided along
|
||||
with the Derivative Works; or, within a display generated by the Derivative
|
||||
Works, if and wherever such third-party notices normally appear. The contents of
|
||||
the NOTICE file are for informational purposes only and do not modify the
|
||||
License. You may add Your own attribution notices within Derivative Works that
|
||||
You distribute, alongside or as an addendum to the NOTICE text from the Work,
|
||||
provided that such additional attribution notices cannot be construed as
|
||||
modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and may provide
|
||||
additional or different license terms and conditions for use, reproduction, or
|
||||
distribution of Your modifications, or for any such Derivative Works as a whole,
|
||||
provided Your use, reproduction, and distribution of the Work otherwise complies
|
||||
with the conditions stated in this License.
|
||||
|
||||
#### 5. Submission of Contributions
|
||||
|
||||
Unless You explicitly state otherwise, any Contribution intentionally submitted
|
||||
for inclusion in the Work by You to the Licensor shall be under the terms and
|
||||
conditions of this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify the terms of
|
||||
any separate license agreement you may have executed with Licensor regarding
|
||||
such Contributions.
|
||||
|
||||
#### 6. Trademarks
|
||||
|
||||
This License does not grant permission to use the trade names, trademarks,
|
||||
service marks, or product names of the Licensor, except as required for
|
||||
reasonable and customary use in describing the origin of the Work and
|
||||
reproducing the content of the NOTICE file.
|
||||
|
||||
#### 7. Disclaimer of Warranty
|
||||
|
||||
Unless required by applicable law or agreed to in writing, Licensor provides the
|
||||
Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
|
||||
including, without limitation, any warranties or conditions of TITLE,
|
||||
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
|
||||
solely responsible for determining the appropriateness of using or
|
||||
redistributing the Work and assume any risks associated with Your exercise of
|
||||
permissions under this License.
|
||||
|
||||
#### 8. Limitation of Liability
|
||||
|
||||
In no event and under no legal theory, whether in tort (including negligence),
|
||||
contract, or otherwise, unless required by applicable law (such as deliberate
|
||||
and grossly negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special, incidental,
|
||||
or consequential damages of any character arising as a result of this License or
|
||||
out of the use or inability to use the Work (including but not limited to
|
||||
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
|
||||
any and all other commercial damages or losses), even if such Contributor has
|
||||
been advised of the possibility of such damages.
|
||||
|
||||
#### 9. Accepting Warranty or Additional Liability
|
||||
|
||||
While redistributing the Work or Derivative Works thereof, You may choose to
|
||||
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
|
||||
other liability obligations and/or rights consistent with this License. However,
|
||||
in accepting such obligations, You may act only on Your own behalf and on Your
|
||||
sole responsibility, not on behalf of any other Contributor, and only if You
|
||||
agree to indemnify, defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason of your
|
||||
accepting any such warranty or additional liability.

The esp_lcd panel (`esp_lcd_nv3031b.c`) is adapted from Espressif's
|
||||
[esp_lcd_sh8601](https://github.com/espressif/esp-iot-solution/tree/master/components/display/lcd/esp_lcd_sh8601),
|
