Waveshare_ST7262_LVGL is an Arduino library designed for Waveshare ESP32-S3-Touch-LCD-7 using ESP32-S3 SOC with 7 inch ST7262 LCD and GT911 touchscreen to facilitate rapid GUI development using LVGL.
| Library | Version |
|---|---|
| LVGL | >=8.3.0 && <=8.3.11 |
| ESP32_Display_Panel | >=0.1.4 |
| ESP32_IO_Expander | 0.0.3 |
To use the built-in examples and demos of LVGL uncomment the includes below respectively.
- You need to copy
lvgl/examplesfrom Arduino Global Libraries folder tolvgl/src/examples. - Similarly for the demos
lvgl/demostolvgl/src/demos.
#include <Arduino.h>
#include <Waveshare_ST7262_LVGL.h>
#include <lvgl.h>

/**
* Or try out a demo.
* Don't forget to uncomment header and enable the demos in `lv_conf.h`. E.g. `LV_USE_DEMOS_WIDGETS`

/**
* You can use toggle_backlight function to toggle lcd backlight
* It uses IO Expander to write HIGH or LOW value based on isOn and toggles isOn value as well
*/
// toggle_backlight(int &isOn);

void loop()
{
Serial.println("IDLE loop");
delay(500);
}Example code was sourced from Waveshare Wiki Page mentioned below. I just made it easier to implement in any sketch file.
