单片机播放音乐 通过控制高低电平让蜂鸣器发出不同的声音 做相应的延时实现节拍 开发环境是keil-SCM music by controlling the high-low so that the buzzer sounds different delay accordingly to achieve the beat

基于AT89C52的单片机4X4键盘原理图，可用于小系统板-Based on AT89C52 microcontroller 4X4 keyboard schematics, can be used for a small system board

PC 通过串口工具在发送节点A 端输入想要发送的数据，点击发送，在接收节点B 端 PC 上的串口工具上，可以看到节点B 收到的内容。如要发送10 个字节内容为11 22 33 44 55 66 77 88 99 AA 的数据/时，在发送节点A 端的串口工具上输入 0A 11 22 33 44 55 66 77 88 99AA，其中0A 代表要发送数据的长度，以16 进制表示。在接收节点B 端的串口工具上就可以收到相应的数据。-PC through the serial port tool sending node A wants to send data from client input, click on send, at the receiving node B-side on a PC serial port tools, you can see the node B received. If you want to send 10 bytes of content 11 22 33 44 55 66 77 88 99 AA of the data/pm at the sending node A on the input side of serial port tools 0A 11 22 33 44 55 66 77 88 99AA, in which you want to send on behalf 0A the data length to 16 hexadecimal said. Node B at the receiving end of the tool on the serial port can receive the corresponding data.

介绍了一种基于MCS251 系列单片机的温度测控电路。可对外界温度进行测 量、误差修正、判定传感器故障与高温报警, 并具有键盘控制和警情通讯显示功能。-VERY GOOD

本程序是用于通用同步和异步串行接收器和转发器（ＵＳＡＲＴ），使用中断方式异步接收和发送数据通信源的程序文件。-this procedure is common for serial synchronous and asynchronous receiver and transponder (USARTs), the use of asynchronous interrupt receive and transmit data communication source program files.
