PIC单片机的配置字总结

平台为：MPLAB V8.92，这个ID有两个编译选项：DEBUG和RELEASE，那么可以根据系统预定宏来自动根据选择模式，配置配置字。

一、PIC18F系列配置字编写

MUC: PIC18F4550

IDE: MPLAB V8.92

编译器：MCC18 V3.47

配置字讲解帮助手册在编译器如下目录：doc\hlpPIC18ConfigSet.chm

例如：D:\Program Files\Microchip\mplabc18\v3.47\doc\hlpPIC18ConfigSet.chm

注意：配置字文件必须只能有main.c文件包含。。。。。。

配置字编写：以18F为例

#ifdef __DEBUG

#pragma config EBTRB = OFF

#else

#pragma config EBTRB = ON

#endif

这段代码就编译预定义宏__DEBUG，然后根据用户选择编译模式自动打开和关闭读保护

例子：

#ifndef __PIC18F4550_CONFIG_H__

#define __PIC18F4550_CONFIG_H__

#include <p18cxxx.h>

//看门狗

#define WDT_ENABLE 0//1:打开；0:关闭

//USB

#define USB_ENABLE 0//1:打开；0:关闭

//PLL Prescaler Selection bits

//96 MHz PLL Prescaler

/*

PLLDIV = 1 No divide (4 MHz input)

PLLDIV = 2 Divide by 2 (8 MHz input)

PLLDIV = 3 Divide by 3 (12 MHz input)

PLLDIV = 4 Divide by 4 (16 MHz input)

PLLDIV = 5 Divide by 5 (20 MHz input)

PLLDIV = 6 Divide by 6 (24 MHz input)

PLLDIV = 10 Divide by 10 (40 MHz input)

PLLDIV = 12 Divide by 12 (48 MHz input)
