单片机编程 PIC单片机程序设计基础
1、程序的基本格式先介绍二条伪指令：EQU ——标号赋值伪指令ORG ——地址定义伪指令PIC16C5X在RESET后指令计算器PC被置为全“1”，所以PIC16C5X几种型号芯片的复位地址为：PIC16C54/55：1FFHPIC16C56：3FFHPIC16C57/58：7FFH一般来说，PIC的源程序并没有要求统一的格式，大家可以根据自己的风格来编写。但这里我们推荐一种 ...
单片机编程 汇编语言程序设计PPT

单片机编程 4位八段数码管的十进制加计数仿真实验(含电路图和仿真文件)
4位八段数码管的十进制加计数仿真实验，程序采用汇编语言编写。此程序在仿真软件上与EDN-51实验板上均通过。仿真图中的数码管位驱动采用74HC04，如按EDN-51板上用想同的PNP三极管驱动在仿真软件上则无法正常显示。程序共分5块，STAR0为数据初始化，STAR2为计数子程序，STAR3为4位数码管动态显示子程序，STAR4为按键扫描子程 ...
