VB串口通讯实例 高精度电压表(24bit) VB源程序，很不错的，不信你就来看看！-VB serial communication example high precision voltage meter (24bit) VB source code, it is good, do not believe you take a look at!

DS18B20测温，DS1302计时，1602液晶显示，带有蜂鸣器报警，可以设定时间-DS18B20 temperature measurement, DS1302 timing, 1602 liquid crystal display with buzzer alarm, you can set the time

sja1000与串口通信的程序，用串口通信助手可观察结果-SJA1000 with serial communication procedures, using serial communication assistant can be observed

智能计数器，对外部信号脉冲进行计数，并将脉冲个数显示出来。 基本要求：计数至少65536个脉冲，并将脉冲个数显示出来。 -intelligent counter, the external signal pulse counting, pulse number will be displayed. Basic requirements : at least 65,536 Count pulse, and pulse number displayed.

头件的中的#ifndef，这是一个很关键的东西。比如你有两个C文件，这两个C文件都include了同一个头文件。而编译时，这两个C文件要一同编译成一个可运行文件，于是问题来了-The first pieces of# Ifndef, this is a very key things. For example, you have two C file, the two C files include the same file size. And compile-time, the two C files to compile together into a run file, then issue the

程序详细功能介绍： * 利用AT89S51单片机的P0端口的P0.0－P0.7连接到一个共阳数码管的a－h的笔段上， * 数码管的公共端通过三极管8550选通。在数码管上循环显示0－9数字，显示时间的间隔可通过修改延时程序。 -Procedures detailed functional Introduction:* use AT89S51 MCU port P0 is connected to P0.0-P0.7 Yang a total digital control of the a-h T segment,* digital tube through the public side-gated transistor 8550. In the digital control on the circulation figures 0-9 show, indicating the time interval may be delayed by modifying the procedures.
