Postby panilsunil » Tue Dec 10, 2024 1:43 pm

My RGB LCD with touch have many addresses on bus. Do i need to add each device using i2c_master_bus_add_device. (26 Dev Handles).
Can they be controlled using a single (i2c_master_dev_handle_t) Dev. Ref: https://www.waveshare.com/wiki/ESP32-S3-Touch-LCD-4.3B
