DoubledImplement2

说明：  基于点阵屏的51单片机贪吃蛇小游戏，附带多种功能。非keil工程，使用codeblocks+sdcc编译，代码与keil工程有些许不同。(Based on the dot matrix screen 51 MCU Snake game, with a variety of functions. For non keil projects, code blocks + Sdcc are used to compile. The code is slightly different from keil projects.)

设计并制作用于电池储能装置的双向DC-DC变换器，实现电池的充放电功能，功能可由按键设定，亦可自动转换。(A bidirectional DC-DC converter for battery energy storage is designed and implemented to realize battery charging and discharging functions. The functions can be set by the button and also can be automatically converted.)

This program operate mathematic functions on numbers

STM32F2XX系列单片机开发板的库函数 (Library Functions STM32F2XX Series MCU development board)

实现简单自动售货机的基本功能。投币找零功能，并用Led数码管显示，输出结果用Led显示。(Basic functions simple vending machines. Coin change for function and use Led digital tube display, the output display Led.)

MPU6050通过STM32F429发送数据到上位机。或是通过显示屏显示。(MPU6050 sends data to PC through STM32F429. Or display it on a screen.)

RS485主机从机通信，程序分模块变成，注释详细(RS485 master slave communication, procedures, sub-modules into a, more notes)

说明：  可以通过stm32控制ad8370的增益(Control the gain of AD8370 with stm32)
