ADS1258开发，程序源代码，还要20字 好恶心(ADS1258 development, source code, but also the word disgusting 20)

基于单片机的霍尔传感器测速源码，带有蜂鸣器报警功能。(Hall speed sensor based on single-chip computer source, with a buzzer alarm function.)

proteus仿真，以LPC2138芯片为核心生成PWM波，控制升压斩波电路（PWM），实现稳定的高电压输出。包含AD转换、串口通信。(proteus simulation. This design use PWM wave generated by LPC2138 to control boost circuit and realized a steady high voltage output. ADC and serial port communication are involved in the design.)

《无线通信系统仿真--C++实用模型》一书的配套源代码，里面包含了，通信系统的所有模块，对学习通信和C++有很好的借鉴()

modbus规约通讯测试小工具-工作空间。利用mfc实现modbus串行通信(Modbus protocol communications test tool- work space. Using MFC to achieve MODBUS serial communication )

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.)

CH341 上位机软件，支持I2C UART等 接口(CH341 host computer software, support I2C, UART and other interfaces)

说明：  单片机蜂鸣器 对初学单片机的你有很好的帮助(SCM SCM buzzer for beginners to help you have a good)

基于单片机的可燃气体报警器，反应灵敏，报警及时(Based on the single-chip microcomputer combustible gas alarm, sensitive, timely alarm.)
