MCD1实战一,点亮一个LED并持续3秒后熄灭 该实战的目的作为学习和应用MCD1在线调试工具套件，进行项目的软件和硬件 联合调试的范例程序，也就是当做一个用户程序实例，而演示板暂时充当用户电 路的角色。这样就构成了一个软件、硬件齐全的自制项目模拟环境。 本程序实现的功能是，把端口RC的8条引脚全部设置为输出模式，并从RC0输出高电平 从而点亮RC0口的一个LED,持续3秒后LED熄灭. 该程序可用于PIC16F87X(A)所有系列-MCD1 real one, to light a LED and continuously put out 3 seconds after the real purpose for learning and application debugging MCD1 online suite of tools to carry out the project software and hardware examples of joint commissioning procedures, that is, as a user instance, and the demonstration user circuit board to serve as a temporary role. This constitutes a software, hardware, a full range of home-made simulation environment projects. Realize the function of this procedure is that the 8-port RC pin all set to output mode and high output from the RC0 so I RC0 a lit LED, continuous 3 seconds after the LED goes out. The program can be used to PIC16F87X ( A) All Series

用汇编语言实现的倒计时器，利用1C中断每秒中断约18次的特性，在根据中断次数计算时间，每过一秒，时间以十进制显示在屏幕上，时间减到零时程序退出。-Using assembly language implementation of the countdown device, using 1C interrupted about 18 times per second interruption characteristics, in accordance with interruptions computation time, with every passing second, the time displayed on the screen in decimal, the time reduced to zero to quit.
