利用单片机扩展8155芯片 4*4键盘扫描 (8155 to expand the use of single-chip-chip 4* 4 keyboard scanning)

在个是AVR的PDF介绍，内容很详细，也很好，特别适合初学者入门的学习(Here is the introduction of PDF of AVR, which is very detailed and very good. It is especially suitable for beginners to learn.)

lexical analysis of text detail program...

说明：  基于WiFi的温湿度监测与显示，(1)主控芯片采用STM32系列单片机、数字温湿度度传感器DHT11、WiFi模块ATK-ESP8266； (2)通过数字温湿度度传感器DHT11采集数据； (3)将数据通过WiFi模块在电脑上进行显示。(Temperature and humidity acquisition)

单片机基于C8051实现LED模拟交通灯(Microcontroller based C8051 LED simulated traffic lights)

这是一个项目的节点程序，单片机使用avr,无线通信模块使用CC2420(支持Zigbee协议）,此源码包括发送端和接收端(This is a project node procedure, single-chip using avr, of wireless communication module using the CC2420 (support for Zigbee Protocol), the source, including the sending end and receiving end)

液晶例程， 包括画点画线画缓冲条，在液晶上printf的算法(LCD program world，you can study LCD draw points )

应用于污水处理工艺的水泵驱动程序，该程序使用ucos-III操作系统，运行于STM32F407芯片中，具有LCD12864液晶显示程序，菜单程序，USART通讯，SPI通讯，485通讯等功能。(The pump driver used in the sewage treatment process is running on the STM32F407 chip with the ucos-III operation system. It has the functions of LCD12864 LCD display program, menu program, USART communication, SPI communication, 485 communication and so on)

说明：  注:protel电路图 1.INPUT12为高压气压和低压压传感器输入端. 2.OUTPUT为充气输出控制端. 3.当高低压有接地信号时,电机正转,气阀打开. 4.INPUT2低气压时有信号时,充气OUTPUT输出,充气电机转. 5.RS1与RS2是调节阀门距离用地 6.RS3是与气阀电机同步时,是气阀电机的转动圈数传感器. 7.RS4是调节延时时间用地(Note: protel circuit 1.INPUT12 and low-voltage high-pressure pneumatic pressure sensor input. 2.OUTPUT output control for the inflated side. 3. When the high and low pressure have a grounding signal when the motor is transferred, the valve opens. 4.INPUT2 low pressure when there is signal output OUTPUT inflatable, inflatable motor switch. 5.RS1 and RS2 is the regulator valve from the land 6.RS3 synchronous motor with the valve, the valve motor is rotating circle the number of sensors. 7.RS4 delay time to regulate land)
