3*4键盘扫描程序 已加消抖功能 可以扩展为4*4~~~ 只用8个I/O口就能实现...

十五路遥控接收板-15 road remote control receiver

在51单片机上用7279芯片驱动键盘和数码管-51 SCM in 7279 with a chip-driven keyboard and digital tube

本代码是无线遥控中常用的pt2272模块的主控单片机代码，实现了编址发送功能。-the wireless remote control code is used in the main control module pt2272 microcontroller code, Implementation of the address this function.

TC35调试笔记，记录了TC35的部分调试参数，单片机控制GSM模块TC35的方法，发送短信息和接收短信息（TEXT模式），关于PDU格式的短信息发送和接收，详细的中文AT指令集，及其单片机控制tc35的程序。-TC35 debugging notes, recorded some of TC35 debug parameters, single-chip GSM module TC35 control methods, send text messages and receive text messages (TEXT mode), on the PDU format for sending and receiving text messages detailing the Chinese AT instruction set , and its single-chip control procedures TC35.

该原代码应用在cpu(st89le516AD+)上,控制GPRS模块sim100,通过检测系统状态(通电状态,运行状态,AD采样值),通过GPRS模块的短信功能,实现无线报警.-the original source applications in cpu (st89le516AD), GPRS module sim100 control through detection system state (state electricity, running AD values), GPRS module messaging functions, wireless alarm.

课程设计，单片机用的是at89s51，C语言编程，希望对有的同学友邦做-Curriculum design, single-chip microcomputer is used at89s51, C language programming, in the hope that some students do AIA

ad转换，8路温度自动测量，可以设置温度上下限，并能实现控制-ad conversion, 8-way automatic temperature measurement, you can set the temperature of upper and lower limits, and to achieve control of

P89CXX编程器控制CPU接收和控制程序-P89CXX programming control CPU to receive and control procedures
