| Abstract: | The slave USB interface in vehicle travelling data recorder is a deficient way to exchange data between recorder and PC.A host USB design compatible to the vehicle travelling data recorder(GB/T19056-2003) is demonstrated,and how to configured the SL811 as a host USB controller and the realization of accessing the USB disk through FAT file system are introduced.A good means for exchanging data between PC and the vehicle travelling data recorder is given. |
