unable to Autodetect the pins of my board GD32F130C6T6 & UART control

[HRAFRH]

![2024-06-02 21 41](https://github.com/RoboDurden/Hoverboard-Firmware-Hack-Gen2.x/assets/125764830/d41efa82-adf7-4225-94d8-e5968e69acfb

I tried a lot but i need help on detecting the correct pin for only board i got (i think it's a master) that i want to control it using ESP32, but board is not listed in the Wiki could you please help me !!

how is it possible to enable both of them?

I’ve enabled both remote_uart and remote_uartbus one at a time, but I still haven’t figured it out yet.

ok, what did you enabled on the esp

[RoboDurden]

please use your brain. defines_2-1-4.h :

#ifdef HAS_USART0
  #define USART0_TX   PB6
  #define USART0_RX   PB7

  //#define USART0_MASTERSLAVE        // uncomment if this usart is used for master-slave communication
  #define USART0_REMOTE                       // uncomment if this usart is used for optional remote control
#endif

// GD32F130 USART1 GD32F130 TX/RX: (PA14/PA15)AF1 , (PA2,PA3)AF1  , (PA8/PB0)AlternateFunction4
#ifdef HAS_USART1
  #define USART1_TX       PA2
  #define USART1_RX       PA3

  //#define USART1_MASTERSLAVE        // uncomment if this usart is used for master-slave communication
  #define USART1_REMOTE               // uncomment if this usart is used for optional remote control
#endif

ok, what did you enabled on the esp

in the ESP i can only find remote_uartbus, i'm using TestSpeed.ino

#define ESP32       // comment out if using Arduino
// #define HOVERBOARD_MM32  // uncomment if a MM32 Hoverboard firmware is connected (and no GD32 or STM32)
#define REMOTE_UARTBUS  // one serial bus to control them all :-)
#define SEND_MILLIS 100   // send commands to hoverboard every SEND_MILLIS millisesonds

this is all i can get in the serial monitor so far : 00 00 00 00 80 00 00 04 00 00 00 00 00 00 00 00 00 F8 E0 E8 20 80 00 80 20 80 00 00 00 00 01 00 80 00 00 00 00 00 00 00 00 0 00 00 0

and the motor still not moving :(, please @RoboDurden @I-hate-2FA any guidance with the code

[RoboDurden]

Sorry, i will not help you anymore.

please i really don't know what to do!

there is 5 pin that must be set for the board to work it is the 3 hall pin and these 2

please use your brain. defines_2-1-4.h :

#ifdef HAS_USART0
    #define USART0_TX   PB6
    #define USART0_RX   PB7

    //#define USART0_MASTERSLAVE        // uncomment if this usart is used for master-slave communication
    #define USART0_REMOTE                       // uncomment if this usart is used for optional remote control
#endif

// GD32F130 USART1 GD32F130 TX/RX: (PA14/PA15)AF1 , (PA2,PA3)AF1    , (PA8/PB0)AlternateFunction4
#ifdef HAS_USART1
    #define USART1_TX       PA2
    #define USART1_RX       PA3

    //#define USART1_MASTERSLAVE        // uncomment if this usart is used for master-slave communication
    #define USART1_REMOTE               // uncomment if this usart is used for optional remote control
#endif

did you set it correctly already

[I-hate-2FA]

and need to use uartbus mode on both, with correct slave id set
