Question

这是我的头文件代码。

标题文件名 16f877a.h

我的文件名 led.c

#include "16f877a.h" //IC selection
#fuses XT, NOWDT, NOPROTECT, NOLVP
#use delay (clock =20000000) //clock 20MHz
void main(){
    while(1){
        output_B(0xff); //hex to binary output on port B
        delay_us(500); // delay = 500 x clock period.
        output_B(0x00);
        delay_us(500);
    }
}

这些文件位于相同文件夹

中

/家庭/公司/文档/ CCPP / PIC / LedProject

我使用 UBUNTU 12.04 。用 gcc 我编译了一个简单的hello world程序，它运行正常。这是我在终端的命令历史记录

mkdir -p PIC/LedProject
cd PIC/LedProject/
gedit led.c
gcc -Wall -W -Werror led.c -o LedProC

这是我的错误。请帮我解决这个问题

我将this blog称为我的电路

Answer 1

您使用的源代码不是严格C，而是包含许多预处理器命令的扩展程序，例如

#fuses XT, NOWDT, NOPROTECT, NOLVP
#use delay (clock =20000000) //clock 20MHz

这些用于配置PIC处理器。这种C类似语言的编译器对

等函数有内在的理解

delay_us()

您使用的兼容C编译器（gcc）不了解fuse，delay_us等，因此声明了许多错误。

如果你的目标是编程PIC - 我认为是这样，使用这种类型的C，转到MicroChip，CCS或其他地方并获得他们的PIC C编译器。

如果您的目标是在UBUNTU机器上使用gcc进行编程，请不要使用为PIC设计的代码。

BTW：可能存在可在UBUNTU上编译的PIC交叉编译器，但我不知道。

搜索gcc PIC交叉编译器的问题，您可能会发现它已得到解答。
