In this tutorial I am using LVGL library as system logger in this project. I have interfaced the module using ESP32S3 MCU. While 2 LA66 modules were exchanging pingpong messages over 868MHz LoRa band, The MCU is receiving the RF communication report over UART and printing the log messages on a 1.9 8bit TFT display. A simple user interface is designed using squareline software that uses LVGL library.
