Including compression ratio, image restoration computing uptime and peak signal to noise ratio, Monte Carlo simulation method of calculating the American option price and basic description, FMCW frequency modulated continuous wave radar range and angular measurements.

Simplicity Studio下的EFM8SB1例程(One Program of EFM8SB under Simplicity Studio)

lpc2131下输出pwm信号，程序里面有现成的工程模块，可以直接编译运行(lpc2131 next pwm output signal, the program modules which have an existing project, you can directly compile and run)

基于STM32F0xx的CPU卡或智能卡阅读器的设计开发源码，支持T0,T1传输协议，具有较高的参考价值。(Based STM32F0xx CPU card or smart card reader design source development, support T0, T1 transmission protocol, has a high reference value.)

旋转编码器的STM32F103的驱动程序，建议读取旋转编码器的时间间隔为1-10mS一次，经测试，该程序完全可用。(STM32F103 rotary encoder driver, it is recommended to read rotary encoder interval is 1-10mS time, tested the program fully available.)

ARM指令系统和体系结构的学习PPT，对初学者非常有帮助(ARM instruction set and architecture of learning PPT, very helpful for beginners)

* 本文件实现串口发送功能（通过重构putchar函数，调用printf；或者USART_SendData() * 这里是一个用串口实现大量数据传输的例子，使用了DMA模块进行内存到USART的传输 每当USART的发送缓冲区空时，USART模块产生一个DMA事件， 此时DMA模块响应该事件，自动从预先定义好的发送缓冲区中拿出下一个字节送给USART 整个过程无需用户程序干预，用户只需启动DMA传输传输即可 在仿真器调试时，可以在数据传输过程中暂停运行，此时DMA模块并没有停止 串口依然发送，表明DMA传输是一个独立的过程。 同时开启接收中断，在串口中断中将数据存入缓冲区，在main主循环中处理([NO ENGLISH])

Including script files and function files in the form, The received signal is given eye and BER simulation systems, About ultrasonic parking radar ranging.

说明：  Lib for MAX31865 use STM32F051c8t6
