8255输入输出实验程序代码，适用于LAB8000通用微控制器实验系统(8255 input-output experimental procedure code applies LAB8000 general-purpose microcontroller experimental system)

MICROSOT 做ACTIVE MOVE FLASH的东东,此说明是其SDK的一部份(MICROSOT make the ACTIVE MOVE FLASH Dongdong, this note is a part of its SDK)

单片机实验中的键盘扫描实验，用lcd1602液晶显示屏显示按键值，c语言编写(for 51)

基于Keil的51工程-1602移位显示(51 works based on Keil-1602 shift display)

关于51单片机和dac7811芯片之间通信的程序，可以正确模拟SPI串口通信，写入数据(On communication between 51 single chip microcomputer and dac7811 chip procedures, can correctly simulate the SPI serial communication, write data )

循环冗余校验16位的，c语言编程环境，能够正常运行，程序详细注释(16 bit cyclic redundancy check, C language programming environment, normal operation, procedures detailed notes)

液晶显示屏OCMG源程序代码，采用的方式为串口驱动。(LCD OCMG source code, the approach for the serial port driver.)

单片机串口发送程序，试一次课设做的，非常非常好用(Chip serial transmission program, try again Lesson set, very, very easy to use)

一个电表行业专用的基于645规约的电表485通讯抄表程序，可以进行485总线抄表，645规约测试。程序技术要点就是规约数据传输协议的处理，如向电表发送数据时的控制码和数据长度、发送的数据部分(数据标识 + 密码 + 数据)、应答帧长度、结束标志等通讯协议的处理值得大家学习。(A meter-based industry-specific statute 645 meter 485 meter-reading procedure can be carried out 485 meter, 645 Statute of the test. Procedures for the technical elements of the statute is to deal with data transmission protocols, such as sending data to the meter when the control code and data length, send the data section (data logo+ Password+ Data), response frame length, marks the end of the treatment protocol, etc. everyone deserves to learn.)

超声波测距，可以通过串口助手显示，当小于设定值时，显示0，当大于设定值时，显示1(Ultrasonic Ranging, through serial aides showed that when less than the set value, 0, when greater than the set value, indicating a)
