Got it finally working by coding a pure python input callback for lvgl, using sample code from MaixUI.
Not perfect, but allows to get touch screen semi working with LVGL at least.
Will post it later on.
Didn't do it because of the custom build system of MaixPy, didn't know where to put and activate micropython usermods, should be a simple drop and compile op.
No LVGL touchscreen demo does work with MaixPy Amigo.
For once, the i2c pins are not right
https://github.com/sipeed/MaixPy_scripts/blob/6ac4f4e97d596d2132b0be0b1fc6bf4139b2fda7/application/lvgl/lvgl_button.py#L11
These should be 24 and 27 for Amigo.
Then, there is a further error "OSError: [Errno 5] EIO"
when calling ts.init(i2c).
(tried with several firmwares: factory, 0.5.0, 0.5.1, including a custom built one from current master)
In current state, touch panel is not usable with LVGL.
Can you point us to a fix?
