说明：  cordic算法的C语言实现，包含了相应C语言程序，十分珍贵(cordic algorithm C language, contains the corresponding C language procedure is very valuable)

51的4乘4键盘锁液晶时钟程序 带键值锁定(51 4 x 4 keypad lock with a key lock LCD clock program)

VOLTMER IN AVR SERIES ATMEGA 0-5V

说明：  基于STC12C5A60S2的流星灯程序(meteor lights program based STC12C5A60S2 microcontroller )

使用485向外发送0-255的数字。 若开发板的485接收到256个字节数据，会把数据以16进制形式打印出来。(Use 485 to send out 0-255 digits. If 485 of the development board receives 256 byte data, the data will be printed in 16 form.)

说明：  ATK-ESP8266 WIFI模块资料，含说明、手册、源码、原理图(ATK-ESP8266 WIFI Module Data)

四悬翼 源码，mpu6050 超声波测距(Four hanging wing source, mpu6050 Ultrasonic Ranging)

利用stm32的adc1，实现规则转换，检测通道pa6和pa7的电压值，并把他们的值放在数组中。串口显示数据方便调试。(Use stm32 the adc1, implement rules conversion, detection channel pa6 and pa7 voltage value, and put their values ​ ​ in an array. Serial display data to facilitate debugging.)

说明：  STM32F103C8T6的LCD1602驱动程序，实测可用！！(STM32F103C8T6's LCD1602 driver, the actual measurement is available!!)
