详细介绍了编码原理的基础知识，是编程的入门级必备教材(Details the basics of coding theory, is an essential textbook entry-level programming)

主要关于STM32F405开发板上的CAN通信源码，可嵌入到开发板运行，结合LCD显示屏进行数据显示。(About STM32F405 main development board CAN communication source, can be embedded into the development board to run, combined with the LCD monitor for data display.)

板子的芯片是STM32F103RCT6 ，使用STM32CUbeMX配置相当简单：1、配置时钟、USB选项及管脚功能，有二个LED和二个按键2、选择USB功能为HID3、配置时钟4、配置IO口功能这样就完成了配置，再生成工程，整个过程不到1分钟。当然还要在工程里面添加必要的应用程序：1、在usbd_custom_hid_if.c文件里面的__ALIGN_BEGIN static uint8_t CUSTOM_HID_ReportDesc_FS2、在usbd_custom_hid_if.c文件里面的int8_t CUSTOM_HID_OutEvent_FS
