XC8管脚定义

刚接触xc8，以前一直汇编，入门问题多多，大侠们不要笑话。
话说一直以来  #define  led portc,4用的溜溜的，现在C上不会了啊

#define offca  LATDbits.LATD0;

  while(1)
{
LATD=offco;
LATBbits.LATB0=1;
offca=1;
}

编译

  我想用个代号表示某个管脚该怎样啊，同志们

#define PIN0  1<<0
#define PIN1  1<<1
....

LATD |= PIN0;  // 设置
LATD  &= ~PIN0;  // 清除

你的define后面多了个；号吧

刚学C，入门问题多多，一个中断入口就折腾一天
