| Abstract: | The basic structure and the communication protocol of Universal Serial Bus (USB) were introduced in this paper.An RS485-USB converter was designed by using TUSB3410 as the core.The principle of this convert's circuit and a method of programming firmware were analysed.The principle of USB's WDM drivers based on windows was discussed and a method of programing converter's drivers was presented.At last an example of realizing temperature measurement system for a great grain depot was given. |
