Arduino 8路串口全双工通信，1个主机与7个从机同时通信。(Arduino Full duplex communication with 8 serial ports.One host communicates with seven slaves at the same time.)

用单片机仿真的一个定时器,很有意思,里面有仿真文件,可以瞧瞧(Single-chip simulation using a timer, it is interesting, there are simulation file, you can look at)

利用ad9854模块产生频率范围为0到50Mhz的正弦波，方波。(Use ad9854 module generates a frequency range of 0 to 50Mhz sine wave, square wave.)

汇编语言，滑动平均滤波程序，实际应用中。(Assembly language, the moving average filter program, the practical application.)

这是用asm编写的IOA口使用程序，是用16位的凌阳单片机汇编(This is asm2 prepared by the IOA I use the program is the use of Sunplus 16 MCU Series)

本程序为STM32F103VET6单片机和ENC28J60网络芯片实现以太网功能的程序，程序成功的移植了uip1.0协议栈并实现了以太网通信(The program program STM32F103VET6 microcontroller and ENC28J60 Ethernet network chip functions successful transplant program uip1.0 of the protocol stack and Ethernet communication)

基于单片机MSP430的DS1302的时钟芯片编程，实现时钟显示(Based on MSP430 MCU DS1302 clock chip programming, the clock display)

基于PIC16F877A的ht6221红外解码程序，测试通过(program based on pic16f877a，pass)

MPC5604P的RTC中断代码，设置RTC中断的时间间隔约为0.5秒，D1每隔约1秒闪一次(MPC5604P the RTC interrupt code, set the RTC interrupt interval of approximately 0.5 seconds, D1 at intervals of about one second flash once)
