錯(cuò)誤error:  #29: expected an expression
我也在網(wǎng)上搜了一下，可是我√了C99也沒(méi)用

單片機(jī)源程序如下:
#include "stm32f10x.h"

void delay(uint16_t z)
{
      uint16_t i,j;
      for(i=0;i<z;i++)
            for(j=0;j<110;j++);
}

int main(void)
{
      //使能時(shí)鐘
      *(unsigned int *)(0X40021018)       |       =       (1<<3);
      //輸出速度
      *(unsigned int *)(0X40010C00)       |       =       (1<<0);
      //輸出高低電平
      while(1)
      {
            *(unsigned int *)(0X40010C0C)       &       =       ~(1<<0);
            delay(5);
            *(unsigned int *)(0X40010C0C)       &       =       ~(1<<1);
            delay(5);
            *(unsigned int *)(0X40010C0C)       &       =       ~(1<<5);
      }
}

雙目運(yùn)算符中間是不是不能有空格，就像雙引號(hào)和兩個(gè)單引號(hào)是兩回事一樣

帳號(hào)		自動(dòng)登錄	找回密碼
