* feat(board): add support for CYD-2432S028R board and update XPT2046 driver
- Added CONFIG_TT_BOARD_CYD_2432S028R in Kconfig.
- Included support for CYD2432S028R in Boards.h and board.cmake.
- Updated Xpt2046Touch driver to use configuration->spiDevice instead of SPI2_HOST when creating the SPI handle.
- Note: SD card is not working on this board yet.
This commit introduces full support for the CYD-2432S028R board and improves the touchscreen driver flexibility by allowing dynamic SPI device configuration. SD card functionality still needs to be implemented.
* Added a new GitHub Actions job to build firmware for the cyd-2432s028r board
using the existing build-firmware action. This ensures continuous integration
coverage for the new board alongside other supported ESP32 variants.
* Removed unnecessary file
* Refactor CYD-2432S028R board initialization, touch, and SD drivers
- Updated board CMakeLists to use `XPT2046-Bitbang` instead of `XPT2046`.
- Added `YellowSdCard` support and initialized SD card in board configuration.
- Updated SPI pin assignments for touch and SD card to match hardware setup.
- Refactored touch driver to use bit-banged SPI with proper start/stop handling.
- Touch adaptation was based on a merge of:
- https://github.com/NellowTCS/Tactility/blob/main/Drivers/XPT2046-Bitbang/Source/XPT2046-Bitbang.cpp
- https://github.com/ddxfish/XPT2046_Bitbang_Arduino_Library/blob/main/XPT2046_Bitbang.cpp
- Calibration is currently static in code:
Calibration cal = {
.xMin = 100,
.xMax = 1900,
.yMin = 100,
.yMax = 1900
};
This removes the need for manual touchscreen calibration, but code was adjusted to support dynamic calibration in the future.
- Added comments and constants for software SPI touch pins.
- Updated `YellowDisplay` to use new touch driver configuration.
* Refactor XPT2046 touch driver: replace Bitbang with SoftSPI implementation, update CMake and README files
