说明：  c语言示例，学习C语言必备，很好的学习资料。(C language example, learning c language necessary, good learning materials.)

利用Keil C51 和LabVIEW编写程序实现PC与单片机串口通信。 设计任务 PC通过串行口将数字（00 ，01 ，02，03... ，FF，十六进制）发送给单片机，单片机收到 后回传这个数字，PC接收到回传数据后显示出来，若发送的数据和接收到的数据相等，则串 行通信正确，否则有错误。启始符是数字00，结束符是数字 FF。(Use Keil C51 and LabVIEW programming to achieve PC serial communication with microcontroller. Displayed after the PC via the serial port design task digital (00, 01, 02,03 ..., FF, hex) is sent to the microcontroller, the microcontroller receives return this figure, PC receives the return data , if the data sent and received data are equal, the serial communication is correct, otherwise an error. Startup character is a number 00, the end of the character is a number FF.)

基于STM32F4的示波器的源代码，内部含有ucos-ii操作系统。(STM32F4 based oscilloscope source code contains an internal ucos-ii operating system.)

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.)

利用C-C++语言编程，实现电子钟的整点报时（从离整点的前9秒开始），并伴随音乐声(The use of C-C++ language programming, electronic bell the whole point of time (from the point from the whole nine seconds before the start), and accompanied by music)

说明：  stm32读取ADS1220芯片多路电压(STM32 reads multiple voltage of ads1220 chip)

这是有关pwm的控制，可以控制它周期的长短来控制灯的亮度，还可以控制它自动调光。(This is the control of the pwm, the length of the cycle it can be controlled to control the brightness of the lights can also control the automatic dimming.)

基于atmega16l usart的实现(atmega16 usart)

stm32 mpu6050 包含上位机以及程序，说明文档。(Stm32 mpu6050 contains the host computer, as well as procedures, documentation.)

LPC1788单片机的DMA调试程序，实现串口DMA功能例程(DMA debug program for PC1788, DMA to serial port function routines)
