说明：  点阵显示原代码，上传的为c语言，也有原理图。(Dot matrix display of the original code, upload the c language, but also schematic.)

TDC-gp21超声波时间测量，用于热表中测量逆流与顺流的时间，进出口温度以及高速晶振的校准 基于430开发，开发环境 IAR5.1(TDC- gp21 ultrasonic measuring time, time for heat measurement of upstream and downstream in the table, the import and export temperature and the calibration of high-speed crystals Based on the 430 development, IAR5.1 development environment)

说明：  基于MODBUS协议的单片机通信系统，上位机+下位机(MODBUS Protocol-based communication system microcontroller)

智能指针的设计，主要为了解决野指针的问题(Smart pointer design, mainly in order to solve the problem of dangling pointers)

which will use for MPC837XERDB when programming

这是一款模拟modbus从机的程序，可以方便用户调试modbus程序，本程序完全免费。(This is a simulation of the modbus from machines, can facilitate users to debug the modbus program, this program is completely free. )

单片机串口通信的应用，通过串口，我们的个人电脑和单片机系统进行通信。 个人电脑作为上位机，向下位机单片机系统发送十六进制或者ASCLL码，单片机 系统接收后，用LED显示接收到的数据和向上位机发回原样数据。(Single-chip serial communication applications, through the serial port, our personal computers and SCM systems to communicate. PC as a PC, send down bit microcontroller system or ASCLL hexadecimal code, after receiving the SCM system with LED display received data and sent back up crew as data.)

新编MCS-51单片机应用 完本。 希望对大家有用(New MCS-51 microcontroller applications complete this. I hope useful)

此程序包括了12864液晶的驱动，以及画线函数、打点函数、显示图片函数、显示汉字函数等等。几乎包括了用户所需要的所有函数(This program includes a 12,864 LCD driver, as well as drawing a line function, RBI function display picture function, display Chinese characters function and so on. Includes almost all the functions required by the user)

说明：  单片机c语言 初学者有用 有例子哦 (SCM c language for beginners there are examples of useful oh)
