    Hello Elda,

    The GUI uses UART to communicate with q76pl455 and LS0432 MCU. There are two UART interfaces: MCU to PC, MCU and BQ76pl455. SCI/LIN is used to interface with bq76pl455, and N2HET emulated UART is used to communicate with PC.

    Two modifications has to be make:
    1. remove two resistors: R8, R9
    2 add 1 wire between FT2232 (U2) pin38 and pin2 of J4, another wire between FT2232(U2) pin39 and pin0 of J4
