|
|
* > GT911: touch_gt911_read_cfg(352): GT911 read error!
|
|
* This might not be a problem with a lipo, but I haven't been able to test that.
|
|
* I tried to solve it just like I did with the keyboard:
|
|
* By reading from I2C until it succeeds and to then init the driver.
|
|
* It doesn't work, because it never recovers from the error.
