说明：  基于stm32，实现4*4按键。文件中.c和.h文件可直接添加到自己的项目中(Based on STM32 development, 4*4 matrix key is realized. The. C and. h keys can be added directly to the kile framework.)

mq2,mq7的例程,基于stm32的例程(Mq2, mq7 routines, STM32 - based routines)

说明：  stm32f103c8t6、ds1302的电子时钟电路+程序设计(Electronic clock circuit + program design of stm32f103c8t6 and DS1302)

C8051F340实现的USB键盘源代码，包括物理按键键值的获取，USB底层协议的实现、USB数据传输的实现。(C8051F340 USB keyboard source code, including the acquisition of physical keys keys, USB underlying protocol implementation, USB data transfer is achieved.)

说明：  ADC0809的接口测试程序。写得很好，大家学习一下。(ADC0809 interface test procedure. Was very well written, we learn about.)

该程序实现了利用滑动变阻器的改变，在LCD上跟随显示当前A/D转换器件的转换值、转换后的电压值，电压值要求精确到小数点后两位。转换值要求用16进制数显示出来。(The program implements the use of sliding rheostat changes follow on the LCD displays the current A/D conversion device of the conversion value, the converted voltage value, voltage value required precision to two decimal places. Conversion value required is displayed with a hexadecimal number.)

基于K60的PID调速，飞思卡尔都要用到，很重要的(K60 is based PID control, Freescale must be used, it is important)
