I’m using esp32 and platformIO
I’d like to use up/down/left/right/OK external keys to navigate the GUI and found there is a touchpadless navigation example which is I’m lookinfg for. It navigates among the objects using the Tab key. But when I look into the code, I don’t see the code reads external tab key or arrow key. Does anyone know how it works? Even in lv_indev.c there is no code handle tab/up/down keys. Thank you very much!
