Hi all, I am thinking of implementing an USB host on a data logging device and are looking at various method of doing it. My final intention is to attach a pen drive ( which are cheaply and readily available ) to the data logging device and remove it after a month and copy whatever data stored in the pen drive to a pc. >From information gathered on the net, it seems that most USB host are implemented on higher end micro processor. I intend to build the USB 1.1 host that will only access pen drive. I understand that i also have to write the interface for the FAT32. Any suggestions or ideas or valuable links? Thanks.
