Max7219驱动四位数码管LED，用于AVR mega64单片机，已经调试通过。

单片机C51串口中断接收和发送测试例程（含通信协议的实现）-C51 single-chip serial port receive and transmit interrupt routine test (including the realization of communication protocols)

用8051单片机控制的8个LED等的跑马功能，具有花样变化，暂停和变速功能-By 8051 the control of eight LED functions such as horse racing, with pattern changes, suspension and transmission functions

实现DS18b20数字温度传感器的测温！-Digital temperature sensor DS18B20 realize the temperature measurement!

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.
