说明：  基于stm32单片机做的无刷直流电机的矢量控制(Vector Control of Brushless DC Motor Based on Stm32 Single Chip Microcomputer)

zigbee CC2530 SPI通信范例(zigbee CC2530 SPI communition examples)

基于STC89C51RC的水平倾角XYZ检测仪(Horizontal dip XYZ detector STC89C51RC)

说明：  基于STM32的Hart程序,,4_20电流的HART通讯协议程序。(Hart program based on STM32, 4_ HART communication protocol program for 20 current.)

单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)

说明：  51单片机的PWM 的汇编语言程式与protues电路图仿真(51 PWM MCU assembly language programs and protues circuit simulation)

使用8脚单片机STC15F104E DS1307 DS18B20 以及LCD1602 红外接收头制作的迷你时钟，其中驱动1602只使用了两个IO口。遥控器芯片兼容HT6122，采用状态机方式完成解码。(Use 8-pin microcontroller STC15F104E DS1307 DS18B20 and LCD1602 produced mini infrared receiver clock, which drives 1602 using two IO ports. Remote control chip is compatible with HT6122, accomplished using the state machine decoder.)

stm8l151寄存器例程,UART发送字符串,简单用于学习STM8L寄存器(stm8l151 register routines, UART transmit string, simply register for learning STM8L)

msp430和18b20的程序，是51改过来的(MSP430 and 18b20 procedure is changed over from the 51)

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)
