8个单片机小程序，对串口、中断的学习很好理解。(8 SCM applet, the serial interrupt learning well understood.)

说明：  基于STM32F1x的ADC电压检测代码(ADC Voltage Detection Code Based on STM32F1x)

4X4点阵键盘+1602液晶显示做的计算器（AVR单片机）(4X4 matrix keyboard 1602 LCD calculator to do (AVR microcontroller))

mavlink协议的CRC校验程序，输入对应的MAVLINK消息帧，输出该消息帧的CRC校验位。(Mavlink protocol of the CRC validation process, enter the corresponding MAVLINK message frame, the output of the message frame of the CRC check bit.)

基于STM32多功能虚拟信号分析仪 示波器频谱仪(Based on STM32 Multifunction virtual signal analyzer oscilloscope spectrum analyzer)

同时使用STM32三个串口的接收与发送，串口1使用printf(),串口2使用u2_printf(),串口3使用u3_printf().接受采用定时器中断超时，5ms未接收到数据认为本次接收结束，置位相应的标志位，主程序检测并处理接收数据。(STM32 simultaneously receive and send three serial, serial port 1 to use printf (), 2 serial ports use u2_printf (), 3 serial ports use u3_printf (). Accepting timer interruption timeout, 5ms does not receive data that the receiving end of this, set the appropriate flag, the main program to detect and process the received data.)

说明：  对STM32单片机内部的温度进行测量，主要靠的是内部传感器(Temperature measurement in STM32 single chip computer mainly depends on internal sensors.)
