说明：  基于51单片机的多路数据采集系统 设置3个功能键：1） 8路数据采集功能 2） 计数功能 3） 秒表功能(51 Microcontroller based multi-channel data acquisition system set up three function keys: 1) 8 channel data acquisition function 2) counting function 3) Stopwatch function)

本程序是自己制作的一种4位数码管模块的内部程序，该模块用于大屏上动态数据的显示，通过RS485接口为其传送待显示数据，芯片是89C2051(This program is a four to produce their own digital control module' s internal procedures, the module for large-screen display of dynamic data, transmitted through the RS485 interface for data to be displayed, the chip is 89C2051)

Rarely found CNG development KIT by MSDN. Enjoy!!!

说明：  使用STM32单片机驱动dds模块，这里的dds模块为正点原子的模块(Using STM32 MCU to drive the DDS module, where the DDS module is the module of positive atom)

说明：  关于stm32系列所有芯片的内部IC的读取操作，属于高级历程；(About the high-level application of STM32 chip part of the code process, STM32 code.)

使用超声波测量距离，可以参考一下这个代码，适用于32。(Using ultrasonic to measure distance, you can refer to this code, which is suitable for 32.)

采用51核单片机+375A usb主控芯片驱动hp打印机，该源码已完全调试ok。(51 nuclear Singlechip+ 375A usb host chip driver hp printer, the source has been fully debug ok.)

syb12864驱动程序，程序为三元晶公司的无字库12864液晶驱动(syb12864Drivers,Program s ternary crystal LCD driver 12864 free fonts)

用multisim中设计的IGBT驱动保护电路(an igbt drive and protect circuit by multisim)

有关 C语言的CRC校验的资料，很实用，值得收藏和学习(About the C language, the CRC data, it is practical, it is worth collecting and learning)
