说明：  在SMT32F7平台上的基于FreeRtos系统的Lwip1.4的移植(Transplantation of Lwip1.4 Based on FreeRtos System on SMT 32F7 Platform)

Abstract—This paper describes a new approach for a course and laboratory designed to allow students to develop low-cost prototypes of robotic and other embedded devices that feature Internet connectivity, I/O, networking, a real-time operating system (RTOS), and object-oriented C/C++.

按键控制PWM占空比，利用按键控制PWM的占空比调节直流电机转速，LED显示(Key control PWM duty ratio)

STM32F407 开发EC20代码，EC20建立一路SOCKT发数据_TCP(字符和十六进制)(STM32F407 develops EC20 code, EC20 establishes SOCKT sending data _TCP (character and hexadecimal))

PowerPCB/PADS封装库，原版安装后没有的，有常见的SO、SOIC、TSSOP等格式，省去自己画封装的麻烦(PowerPCB/PADS package library, after the original installation, and have common SO, SOIC, TSSOP and other formats, saved themselves the trouble of packaging draw)

STM8单片机实现0.96OLED驱动，方便初学者(iic OLED driver for STM8)

使用AD7147作为电容式的触摸按键设计(Using the AD7147 as a capacitive touch button design)

个人制作的电磁智能平衡直立小车的源程序，希望对有心人有用！(Individuals produced by electromagnetic intelligent balance upright trolley source, I hope to be useful off!)
