DMX512灯管控制程序，欢迎使用，，可以换灯光颜色.rar(DMX512 lamp control program, welcome to use, can change the color of light, .Rar)

用51单片机模拟dds产生正弦波，方波，三角波，幅度频率可控。(Dds generated using 51 MCU simulation sine, square, triangle wave, amplitude frequency control.)

压缩包包含有工程文件对应的电路图，以及电路图对应的LINslave节点的完整工程文件适用于MB95200系列单片机(Compression bags containing the corresponding circuit engineering documents, and the circuit node corresponding LINslave complete project file for the MB95200 Series MCU)

说明：  ZH03B激光粉尘传感器（PM2.5传感器）-炜盛科技(ZH03B Laser Dust Sensor (PM2.5 Sensor) - Weisheng Technology)

atmel单片机开发的mp3,里面有原理图及源代码.(atmel microcontroller development of the mp3, with a diagram and the source code.)

说明：  该程序基于STM32F767实现双串口通信交互、触摸屏交互实验。(The program is based on stm32f767 to realize the experiment of two serial port communication interaction and touch screen interaction)

该模块实现串口DMA发送中断接收，与系统或者外设通信，一发一答的方式，发送一帧数据，需等待对方应答，如果在规定时间内未等到ACK数据，发送端 会重发该数据，采用状态机制原理，对串口使用以及协议搭建很参考价值(The module DMA send serial interrupt receiving, and system or peripheral communication, one answer, send a frame of data, need to wait for the answer, if ACK did not wait until the data within the specified time, the sender will retransmit the data, using the state mechanism principle, build a reference value for the use of serial port and protocol)

STM32串口，基于stm32开发板实现的串口通信程序。(STM32 serial demo)

说明：  arduino 8*8像素点阵实现代码(Arduino 8*8 Pixel Matrix Implementation Code)

说明：  用51单片机，使用AD芯片，达到雨越大，雨刷越快的效果(With 51 single chip microcomputer, the use of AD chip, the bigger the rain, the faster the wiper effect)
