Request for Assistance with UART Communication Between FR8008GP and External Microcontroller



  • I am currently working on a project involving the FR8008GP series in a LCD rotary knob, and I need to establish UART communication between the FR8008GP which is in LCD rotary knob and an external microcontroller like Arduino UNO/Mega2560 or RP2040 Pi pico. Despite my efforts, I have encountered some challenges in setting up the communication.

    Please, kindly provide guidance or share any relevant documentation, sample code, or best practices for configuring UART communication between the FR8008GP and an external microcontroller.
