基于芯片LPC2132的PWM_DAC基本实验(Based on the the chip the LPC2132 s PWM_DAC basic experimental)

This class can create DataEntryWriter instances based on class paths. The writers will wrap the output in the proper jars, wars, ears, and zips.

红外遥控解码，基于51单片机的例程，简单实用，我在学习单片机的时候用到的(Infrared remote control decoding, based on 51 MCU routine, simple and practical, I used the time to learn microcontroller)

说明：  电力系统 导纳矩阵的形成 数据输入按IEEE标准(Power system admittance matrix of the form data input by IEEE standard)

正点原子STM32F103精英板跑马灯例程(Punctual Atomic STM32F103 Elite Board Horselight Routine)

RC522 IIC驱动程序，可实现读卡和写卡功能，复旦卡或M1卡都可以，本人也试过读公交卡，可以读出序列号和卡类型。(RC522 IIC driver, can read card and write card function, Fudan card or M1 card can, I also tried to read the bus card, you can read the serial number and card type.)

说明：  测量单片机频率，可以测量周期波的频率，最大可以测到60khz(Measuring Frequency of Single Chip Microcomputer)

巧用C8051F410的PCA实现超声波测距(Using the PCA to achieve ultrasonic ranging C8051F410)

TFT彩色液晶屏底层驱动代码，已经封装好了，可以直接调用。基于89c52单片机。(TFT color LCD screen underlying driver code has been packaged well, can be called directly. Based 89c52 microcontroller.)

avrmega16的频率计源码，在2m以内误差为1-3hz，1602显示(avrmega16 the frequency of source, in less than 2m error 1-3hz, 1602 show)
