嗨、Yanming Luo

"我已经在 main.h 文件中写入了 handleMotorCommands。 如果需要任何修改、请告诉我。"

In main.h file void handleMotorCommands(void)
{
    // Start/Stop the motor based on isMotorOn flag
    if (isMotorOn)
    {
        gMotorVars.Flag_Run_Identify = true;
        printf("Motor is ON\n"); // Debug: Print motor state
    }
    else
    {
        gMotorVars.Flag_Run_Identify = false;
        printf("Motor is OFF\n"); // Debug: Print motor state
    }

    // Set the target running speed
    gMotorVars.SpeedRef_krpm = targetSpeed;
    printf("Target speed set to %ld krpm\n", gMotorVars.SpeedRef_krpm); // Debug: Print target speed
