我老师为上课开发的单片机测试源程序，怎么可能“文件已存在”？...

GZ60的can通信源程序 用c语言编写-can GZ60 of communication with the source language c

串口双工通讯，单片机上用LCD显示主机发送的数据，同时可以通过单片机的按键向主机发送多种数据-Duplex serial communication, single-chip LCD display with a host to send data at the same time can be key to the host MCU to send multiple data

基于80c51的半双工红外发射程序，带键盘可修改发射内容

使用LED显示接收到的数据，使用LCD显示发送的字符 * 程序使用波特率为9600，程序运行时需要在pc机上使用一个串口 * 接收发送程序，发送字符应为asc码，接收的字符为十六进制-The use of LED display received data sent using the LCD display uses characters* for 9600 baud rate, the program needs to run-time machine pc using a serial port* send procedure to receive, send characters should asc yards receiving for the characters Hexadecimal

PC数字电压表的设计,原理图以及代码,设计文档.此数字电压表的优势在于可以通过串口将测量所得到的电压值传给PC机,这样的话有利用整个数据的采集与分析.上位机采取的是串口通信软件.-PC digital voltage meter design, diagram and code, Design Documentation. This figure voltage meter advantage is through the serial port will be measured by the voltage transmission PC, so is the use of the entire data collection and analysis. PC"s serial port communication software.
