A program to consicle very mad and good !! yes :

上位机发送数据包，下位机实现简单数据接，然后可以存储到其他位置(PC to send data packets, lower machine simple data connection, which can then be stored in a different location)

cd4052用stm32来写的程序，，实现电子开关电路 (CD4052 uses STM32 to write the program, the electronic switch circuit)

学习使用contex-m3的stm32f103c6的程序库，LCD1602驱动程序。(Learn to use contex-m3 of stm32f103c6 the library, LCD1602 driver.)

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.

MCU图片解码，使用STM32对JPEG图片解码，(STM32 JPEG decoder code,)

超声波测距（5 28线性处理）,测量线性度很高(Ultrasonic Ranging (528 linear processing), high linearity measurements)

说明：  本程序基于单片机实现RTC实时时钟，简单易懂(The program is based MCU RTC real time clock, easy to understand)

ME850单片机开发实验仪演示程序 - LCD1602显示 基于 c51系列的单片机程序，用AT89S52延时通过(ME850 SCM experimental instrument demo- LCD1602 display based on c51 series SCM process, using AT89S52 delay through)

数码管的显示程序，数码管循环显示900-999~(Digital loop display 900-999 ~)
