我为 ADC 编写了一个函数来读取齿轮值。我不断收到此错误，但我不知道该如何处理它..有建议吗？我的代码是:

void MAIN_vInit(void)
{

   void read_bremspedal();    //This is my ADC read function prototype
   PSW_IEN        =  0;          


  ///  -----------------------------------------------------------------------
  ///  Configuration of the System Clock:
  ///  -----------------------------------------------------------------------
  ///  - VCO clock used, input clock is connected
  ///  - input frequency is 8,00 MHz

  MAIN_vUnlockProtecReg();     // unlock write security

  MAIN_vChangeFreq();          // load PLL control register

  //   -----------------------------------------------------------------------
  //   SCU Interrupt Disable configuration:
  //   -----------------------------------------------------------------------
  SCU_INTDIS     =  0xFFFF;      // SCU Interrupt Disable Register

  //   -----------------------------------------------------------------------
  //   Initialization of the Peripherals:
  //   -----------------------------------------------------------------------

  //   initializes the Parallel Ports
  IO_vInit();

  //   initializes the Capture / Compare Unit 61 (CCU61)
  CCU61_vInit();

  //   initializes the Analog / Digital Converter  (ADC0)
  ADC0_vInit();

  //   initializes the MultiCAN Module (CAN)
  CAN_vInit();


  //   -----------------------------------------------------------------------
  //   Initialization of the Bank Select registers:
  //   -----------------------------------------------------------------------


  //   -----------------------------------------------------------------------
  //   SCU Interrupt Source Selection configuration:
  //   -----------------------------------------------------------------------
  SCU_ISSR       =  0x0000;      // SCU Interrupt Source Select Register

  // USER CODE BEGIN (Init,3)

  // USER CODE END

  MAIN_vLockProtecReg();       // lock write security

  //   globally enable interrupts
  PSW_IEN        =  1;          

} 

 while(1)
  {

   // USER CODE BEGIN (Main,13)

      //Bremspedal

      void read_bremspedal(){   //syntax error - token ";" inserted before "{"
      ADC0_vStartSeq0ReqChNum(0,0,1,3);
      uwbremsen = ADC0_uwGetResultData(RESULT_REG_1);
      uwbremsen >>= 4;
      if(uwbremsen) {            // wenn gebremest!
      CAN_MODATA4LL = uwbremsen;
      CAN_vTransmit(4);         //Rekuperation signal senden
      IO_vSetPin(IO_P10_0);     // Nicht Schalten signal
      }
    }
  }

您在 while 循环内部定义函数“void read_bremspedal(){”。另外，您正在尝试编写一个根本不在任何函数内部的 while 循环。反转代码行，它应该可以工作。以下内容至少应该编译:

void read_bremspedal(){
  // USER CODE BEGIN (Main,13)

  //Bremspedal
  while(1) {
    ADC0_vStartSeq0ReqChNum(0,0,1,3);
    uwbremsen = ADC0_uwGetResultData(RESULT_REG_1);
    uwbremsen >>= 4;
    if(uwbremsen) {            // wenn gebremest!
      CAN_MODATA4LL = uwbremsen;
      CAN_vTransmit(4);         //Rekuperation signal senden
      IO_vSetPin(IO_P10_0);     // Nicht Schalten signal
    }
  }
}

祝你好运!

注意 - 它可能只是复制/粘贴，但当您使用正确的缩进时，确保您拥有正确数量的左括号/大括号会容易得多。每个左大括号后始终缩进至少 1 个(可能是 2-4 个空格)。这应该对将来有所帮助!
