LVGL (Light and Versatile Graphics Library) is a popular free and open-source embedded graphics library to create beautiful UIs for any MCU, MPU and display type, supports working with the TFT_eSPI library. Following previous exercise " Raspberry Pi Pico 2 drive 4.0" 320x480 TFT SPI ST7796 with FT6336U Capacitive Touch + SD, in Arduino framework ", this exercise show steps to add LVGL on top of TFT_eSPI, on Raspberry Pi Pico 2. Install lvgl library in Arduino IDE's Library Manager. Using LVGL with Arduino requires some extra steps: Be sure to read the docs here: https://docs.lvgl.io/master/integration/framework/arduino.html Follow these configuration steps: - Go to the directory of the installed Arduino libraries - Go to lvgl and copy lv_conf_template.h as lv_conf.h into the Arduino Libraries directory next to the lvgl library folder. - Open lv_conf.h and change:   To enable the content of the file:   change the first #if 0 to #if 1   To use T...
