基于51单片机的超声波测距模块使用，使用HC-SR04模块，定时器测量回波长度(Ultrasound Ranging Module Based on 51 Single Chip Microcomputer)

STC单片机检测IO电平变化，并计数，接收到串口指令时，发送计数或者控制继电器输出(STC microcontroller detects the change of IO level, counts and receives the serial port instruction, sends the count or controls the relay output.)

说明：  基于STM32F4 和 ESP8266 通过WIFI和ThinkSpeaker进行通信，传输数据(Communication based on STM32F4 and ESP8266 through WIFI and ThinkSpeaker, transmission of data)

能够贴着左边的墙走，直到走出迷宫，亲测有效。望采纳！！！(Able to stick to the left wall.)

energy emwin驱动程序，可驱动彩屏及相关LCD控制器(energy emwin)

本源码程序为射频通信驱动代码，采用IAR system软件开发，以MSP430单片机为主控芯片，程序集成了CC1120，CC1200，CC1101等多种射频芯片，在使用时可通过用户自己屏蔽不需要的芯片，程序中均已文件分好，各种芯片的代码互不干扰。我已经通过测试，改程序可以直接运行，但用户在使用时需进行IAR软件的路径配置(The source program for RF communication driver code, using the IAR system software development, MSP430 single chip as the main control chip, the program integrates CC1120, CC1200, CC1101 and other radio frequency chip, by the users themselves do not shield chip when in use, the program have the good, various chip code do not interfere with each other. I have passed the test, reform program can be run directly, but the path to configure user required when using IAR software )
