利用Keil C51 和LabVIEW编写程序实现PC与单片机串口通信。
设计任务
PC通过串行口将数字（00 ，01 ，02，03... ，FF，十六进制）发送给单片机，单片机收到
后回传这个数字，PC接收到回传数据后显示出来，若发送的数据和接收到的数据相等，则串
行通信正确，否则有错误。启始符是数字00，结束符是数字 FF。(Use Keil C51 and LabVIEW programming to achieve PC serial communication with microcontroller. Displayed after the PC via the serial port design task digital (00, 01, 02,03 ..., FF, hex) is sent to the microcontroller, the microcontroller receives return this figure, PC receives the return data , if the data sent and received data are equal, the serial communication is correct, otherwise an error. Startup character is a number 00, the end of the character is a number FF.)
