1、Cmos Sensor OS 测试； 2、主控单片机型号：STC15F4K60S4 3、模拟电子开关：CD4051 CD4067BM96 4、单片机控制模拟电子开关自动采集被测Sensor 各PIN的导通压降，将数据通过串口 发送至上位机，上位机接收数据并对数据进行分析判断，给出最终的OS测试结果； 5、单片机10位精度AD 电压采集； 6、支持单片机串口通信；(1, Cmos Sensor OS test 2, the master SCM model: STC15F4K60S4 3, analog electronic switch: CD4051 CD4067BM96 4, the microcontroller controls the analog electronic switch automatically collect test each PIN Sensor voltage drop, sending data to upper computer through the serial port, the PC receives the data and data analysis to determine, given the final OS test results 5, the microcontroller 10 AD precision voltage acquisition 6, support for single-chip serial communication )

jm20316移动硬盘盒---原理图，PCB板图。非常好用的资料(jm20316 HDD Enclosure--- schematics, PCB board map. Very useful information)

EMDA控制器可以在没有cpu的参与下完成映射存储空间的数据传输，这些数据的传输可以是片内外设，片内存储器之间。(EMDA controller can be done without the participation of CPU mapping storage space of data transmission, the data transmission can be set inside and outside, between internal storage.)

这是一份控制方法的C语言实现文档，写的非常好，分享给大家，特别是PID算法，说的还蛮好的(This is a method of controlling the C language document, written in a very good, for everyone to share, particularly in the PID algorithm, that s quite good)

energia的一个无线模块库，新手上路，各位大佬多帮衬。(A wireless module library of Energia)

说明：  基于stm32L151核心板的LoRa无线传输(LoRa wireless transmission based on stm32L151 core board)

C8051f340 8位pwm波形输出 占空比可调节(C8051f340 8bit output )

变频器控制电路，内有详细PCB板。经测试，性能正常，能直接使用。( Inverter control circuit, which has a detailed PCB board. After testing, the performance of normal, can be used directly.)
