How to change the symbol or text (label) in a button in lv_btnmatrix
There is a lv_btnmatrix_get_btn_text(btnm, btn_id) what I to know if there is a way to change the buttons label i.e. like a lv_btnmatrix_set_btn_text(btnm, btn_id);
Or do I have to create a grid of buttons and not use the btnmatrix widget
