如何使用USB总线接口在单片机系统中实现一个虚拟串口的原理和实现过程。在设计中,软件部分采用USB的CDC类标准来实现虚拟串口,这样可以使用操作系统(Windows,Linux)自带的驱动程序;在硬件设计中,使用自带USB从设备接口的AT89C5131单片机,提高了系统的集成度和可靠性-How to use the USB bus interface in single-chip realization of a virtual serial port system, the principle and implementation process. In the design, the software part of the adoption of USB-CDC class standards to achieve a virtual serial port, so you can use the operating system (Windows, Linux) comes with the driver in hardware design, the use of own USB interface from the device chip AT89C5131 machine, to improve the system integration and reliability of

通讯规则:
1:时钟7.3728 MHz/波特率9600/9个数据位/奇校验/1个停止位/硬件多机通讯功能/
2:通讯连接采用硬件MAX485,双向单工
3:每个上行/下行的数据包的字节个数都是一样的(通讯数据量)
4:每个上行/下行的数据包都采用CRC8校验
5:数据接收采用中断+查询的方式
6:总是由主机向从机发送一个数据包,从机收到数据包后向主机回复一个数据包
7:不管是主机还是从机,如果收到的数据包有任何错误,都将丢弃该数据包,等效于没有接收
8:从机之间不能相互通讯,必须通过主机才能交换数据
9:无效地址是0,主机地址是1,从机地址是2.3.4......广播地址是255 -err

美国TI公司的protel 元器件库,在应用中需要更新,本人收集了最新的版本共30M,为提高上传速度分六次上传。文件名依次为TI_1到TI_6。希望大家设计电路板时少走弯路。由于在上传时找不到分类,所以归结为书籍一类-TI" s U.S. Treasury protel components, need to be updated in the application, I collected a total of up-to-date version of 30M, to improve the upload speed upload six hours. File name followed by TI_1 to TI_6. Hope that the design of circuit board less detours. From when can not find in the classification, it comes down to a class of books
