Lesson 7 LVGL Desk Lamp CrowPanel_ESP32_LVGL_Demo

lboue · June 17

Hello,
I trying the lesson 7 LVGL Desk Lamp CrowPanel_ESP32_LVGL_Demo example but I can only see the support coordinates displayed in the console:

Data y 184
Data x 158
Data y 339
Data x 158
Data y 339
Data x 158
Data y 339
Data x 158
Data y 339
Data x 161
Data y 247

Isn't the purpose of this example to show how to change the state of a GPIO output?
How do you trigger an action when pressing the On / Off buttons?

Regards

Thanks, I found the code in the ui_events.c file.

void Lamp_On(lv_event_t * e)
{
    digitalWrite(38, HIGH);
}

void Lamp_Off(lv_event_t * e)
{
    digitalWrite(38, LOW);
}
