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.)

大家好，这是关于密码锁的电路图，需要的话可以参考下( 允许输入拉丁字符的拼音 英语 中文(简体) 日语 Hello, everybody, this is a circuit diagram of the combination lock, if necessary, can refer to the following 允许输入拉丁字符的拼音 英语 中文(简体) 日语 Hello, everybody, this is a circuit diagram of the combination lock, if necessary, can refer to the following)

STM32 SPI读写FM25CL64铁电存储器，程序为103RBT6单片机读写代码，包括SPI初始化、字节发送接收代码、FM25CL64读写代码(STM32 SPI read/write FM25CL64 ferroelectric memory, the application for 103 rbt6 microcontroller, speaking, reading and writing code, including the SPI initialization code byte code to send and receive FM25CL64, speaking, reading and writing )

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.
