PIC18F2220 LED闪烁程序错误
PIC18F2220 LED blinking program error
我是PIC编程的初学者。 This video 我曾经编写过我的第一个程序。
这是我写的代码：
#include <stdio.h>
#include <stdlib.h>
#include "XC8.h"
void main(void)
{
TRISBbits.RB0 = 0;
OSCCON = 0x76;
while(1)
{
LATBbits.LATB0 = ~LATBbits.LATB0;
for (int countDelay=0; countDelay<20; countDelay++) __delay_ms(50);
}
}
我的 XC8.h 头文件是：

希望我已经为查询添加了足够的输入。由于我是这部分的新手，请随时询问更多信息。
您没有包含 #include <xc.h>，而只是设置您的配置位。 xc.h 是主要的头文件，它将包含许多其他头文件，最终指向您的特殊控制器头文件 #include <pic18f2220.h>。它是使用 MPLAB IDE 应该提供的 #ifdef 结构完成的，因为您最初是在创建新项目时设置控制器的。
这个guide from Microchip作为开始非常有用，因为它解释了很多。
如果不包含 <xc.h> 头文件，编译器将不知道控制器的寄存器名称。这就是您出错的原因。
