Hello,
I have a problem with the keyboard. I have the keyboard and 5 button(UP/DOWN/LEFT/RIGHT/ENTER) to launch it I tried to launch it according to the document.
Unfortunately, after pressing the ENTER button several times, the keyboard stops working. And I could not find the problem at all. Please guide me in this matter.
uint8_t my_btn_read(){
uint8_t i=0;
if(UP_KEY==0) i=LV_KEY_UP;
else if(DOWN_KEY==0) i=LV_KEY_DOWN;
else if (RIGHT_KEY==0) i=LV_KEY_RIGHT;
else if(LEFT_KEY==0) i=LV_KEY_LEFT;
else if(ENTER_KEY==0) i=LV_KEY_ENTER;
else i=0;
return (i);
}
void encoder_with_keys_read(lv_indev_drv_t * drv, lv_indev_data_t * data){
uint8_t act_key=0;
act_key = my_btn_read() ;
if(act_key>0) {
data->state =LV_INDEV_STATE_PRESSED;
data->key=act_key ;
}
else {
data->state = LV_INDEV_STATE_RELEASED;
act_key=0;
data->key=0;
}
}
