液晶240*128驱动 用的是PIC单片机 但是可以改 51单片机 里面驱动都一样 就是 拿过来就可以用 (LCD 240* 128 drive using a PIC microcontroller, but can be changed inside the microcomputer 51 is to take over the same driver can be used)

pic18单片机控制tm1629驱动数码管显示 电力无功补偿(Pic18 single chip microcomputer control tm1629 drive digital tube display Reactive power compensation)

说明：  1604 lcd 显示屏写数据写命令 ,(lcd display Write data Write Command,Initialization)

18B20电路图,温度传感器，汇编版与C语言版共有及51开发板上的连线(The 18B20 schematic, temperature sensor, assembly version of the C language version of Total and 51 development board of the connection)

说明：  下面的程序利用友元函数求两点间的距离。请你将有关的程序补充完整，并总结为什么这里要用友元函数来求两点间的距离。(using friend to get the result.)

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.)
