大家好!請教個問題:
xc8編譯器,pic16f1825 單片機(jī) 串口發(fā)送程序編譯不過.代碼如下:
/串口發(fā)送一串字符
void EUSART_SendString(const unsigned char *pData)
{
di(); //GIE = 0 //disable all interrupts
TXIE =0; //屏閉EUSART 發(fā)送中斷
int len = strlen(pData);
unsigned char *str= malloc(len);
if(str !=NULL){
strcpy(str,pData);
while(*str!='\0')
{
TXREG = *str++;
while(TXSTAbits.TRMT==0);//TRMT=1時,TSR為空,否則不為空
}
free(str);
}
}
編譯錯誤 如下:

各位大牛,請幫我看下是什么問題!! |
