心率采样电路，包括原理图，PCB单路及相关说明(Heart rate sampling circuit, including schematic, PCB single)

基于C51单片机的4*4矩阵键盘扫描。有仿真和程序，数码管显示，可以用于学习矩阵键盘扫描的基础知识。并可以进行扩展。(Based on the C51 microcontroller 4* 4 matrix keyboard scanning. There simulation and procedures, digital display, can be used to learn the basics of the keyboard scan matrix. And can be extended.)

只做了时间显示，和温度显示，使用一个按键切换(Only time display, and temperature display, using a button to switch)

使用stm8s系列MCU开发串口通信的范例(Use STM8S series MCU to develope UART)

基于周立功CAN的上位机软件，可以实现对CAN的打开，波特率设置，滤波设置，消息发送，消息接受等等。亲测可用。完全可以作为二次开发的资料。(Based ZLG CAN PC software can be achieved on the open CAN baud rate settings, filter settings, the message is sent, the message to accept more. Pro-test available. Can be used as secondary development information.)
