STM32F103共享电平车无线终端源代码(STM32F103 source code for shared motor,electric bike.)

基于51单片机的 超声波测距 用于智能小车的循迹 蔽障(Ultrasonic distance measurement based on 51 single-chip microcomputer used for tracking of intelligent car escapes)

用c语言写的时钟代码，每隔一秒秒钟增加一(The clock with the c language to write code to add a second every second)

一个用430单片机设计的温控仪表电路图方案。采用protelse99设计的，里面只有电路图、没有pcb图。(A single chip with a 430 temperature controller circuit design program. Designed by protelse99, only the circuit, no pcb diagram.)

说明：  基于51单片机的按键例程，常见问题： 1. 按键无反应 请您确认程序是否下载成功，连线正确无误，确认无误后还是无效果的话，将排线重新插拔下，单片机拿下来重新安装，重启开发板试试！(Key routines based on 51 single chip microcomputer,common problems: 1. Press the key and no response. Please confirm whether the program was downloaded successfully and the connection is correct. If it is still ineffective after confirmation, plug and unplug the cable again, take down the MCU and reinstall it. Restart the development board to try!)

说明：  在stm32f407的平台下，进行TCP的服务器端数据收发(Under the platform of stm32f407, the server-side data of TCP is sent and received)

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)

SQL Server 2005 Service Broker (SSB) is an asynchronous messaging technology built into SQL Server. With SSB, you essentially get the power of messaging technologies like Microsoft Message Queue (MSMQ) combined with the relational database capabilities of SQL Server, all controlled with Transact SQL statements(SQL Server 2005 Service Broker (SSB) is an a synchronous messaging technology built into S QL Server. With SSB. you essentially get the power of messaging tech nologies like Microsoft Message Queue (MSMQ) c ombined with the relational database capabili ties of SQL Server, all controlled with Transact SQL statements)

此程序是带回路断电报警功能的防盗器，当电门锁被强制打开和电瓶主电源线被剪断时会发出连续的报警。(This program is back to the way of power outage alarm alarm, when the main electric door lock was forced open and battery power cord was cut off when the continuous alarm.)

说明：  stm32f103通过spi接口扩展NRF24L01进行通信的例程(stm32f103 communicate with NRF24L01 by spi interface)
