Good,day! I am a LVGL beginner. I want you to be kind.
Description
Is it possible to move and select objects with three physical buttons for complete control?
What MCU/Processor/Board and compiler are you using?
M5stack gray,ArduinoIDE
What do you want to achieve?
1.Moving the focus.
2.An event to the object being focused.(For example, the click of a button)
3.These clever ways.
What have you tried so far?
If the physical button is pressed, it simulates a button click.
Move and select the focus within a click event.
Code to reproduce
Add the relevant code snippets here.
The code block(s) should be between ```c and ``` tags:
bool my_touchpad_read(lv_indev_drv_t * indev_driver, lv_indev_data_t * data)
{
//Click on a button in the screen according to the physical button that is pressed.
if(digitalRead(btn_A)==1){
data->point.x = 10;
data->point.y = screenHeight-10;
}else if(digitalRead(btn_B)==1 ){
data->point.x = screenWidth/2;
data->point.y = screenHeight-10;
}else if(digitalRead(btn_C)==1){
data->point.x = screenWidth-10;
data->point.y = screenHeight-10;
}else{
data->state =LV_INDEV_STATE_REL;
return false;
}
data->state =LV_INDEV_STATE_PR;
return false; /*Return `false` because we are not buffering and no more data to read*/
}
static void win_btn_event_handler(lv_obj_t * btn, lv_event_t event)
{
//Focus processing in the in-screen button event handler.
if(event != LV_EVENT_CLICKED){
return;
}
if(btn == obj_btn_L){
Serial.println("L");
lv_group_focus_prev(g);
return;
}else if(btn == obj_btn_C){
Serial.println("C");
lv_group_send_data(g,LV_KEY_ENTER);
return;
}else if(btn == obj_btn_R){
Serial.println("R");
lv_group_focus_next(g);
return;
}else{
Serial.println("ex");
}
}

Because the M5stack not yet arrived, it is a M5stack-style ESP32.
Thank you!
