stm32 硬件IIC总线

它可用于4位16x2 lcd接口库

用C语言模拟I2C时序功能，已经调试通过，可以直接使用-C language simulation with I2C timing functions, has been through the debugging, you can directly use

我写的 四线 步进电机控制 用M16主控-I wrote the four-wire stepper motor control using M16 control

这是一个SPI总线的读写程序，适合新手入门使用，简单易学，本人就是从这个简单例程开始学习AVR SPI的 希望对新人有帮助-This is a SPI bus to read and write procedures, suitable for beginners to use, easy to learn, my routine is to start from this simple study of the AVR SPI would like to help newcomers

由于普通单片机只有一个串口,由于用户可能会用到多个串口,而对于双串口的单片机价格贵,不如自己动手选择两个IO口,自己模拟串口通讯,以下为模拟串口程序.-Because there is only one common single-chip serial port, as the user might use multiple serial ports, dual serial ports for the price of your microcontroller, it is better to select two IO own mouth that they simulation serial communication, the following for Simulation of serial procedures.
