自行车的里程表。基于51单片单片机最小系统开发的(The bike' s odometer. Developed based on 51 single-chip microcontroller minimum system)

STM32单片机开发例程，这里是外部中断的开发例程(STM32 MCU development routines, here is the development of the external interrupt routine)

串行da模块的应用，和单片机通信，通过单片机控制da模块(Serial da module application, and single-chip communication, via da MCU control module)

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)

HPA就是host protect area(HPA is the host protect area)

基于STM32的直流无刷电机控制程序，带霍尔传感器(Brushless DC motor control procedures)

STM8 C language programming

F340 LCD1602 模块程序 (F340 LCD1602 module program)

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)

cc2430无线射频模块（基于ZigBee2006）的2004协议栈的演示程序和使用说明，刚开始学习或接触ZigBee的朋友可以借此来学习。(cc2430 RF module (based on ZigBee2006) of the 2004 protocol stack demo program and instructions for use, just learning or exposure to ZigBee' s friends can learn.)
