Information on Datalogger and USB Devices

The reason I like using Parallax products is that they come with code examples.· Most of the devices I have connected to my Stamps came with code examples, and that's a large part of the reason I chose those devices.

I have successfully executed the code·provided with·the·Datalogger to access·a USB drive,·but I doubt that I would ever have got this working without the example.·

I have seen·posts on several occasions talking about connecting to USB devices using a Datalogger.· I have read the FTDI details, and I think I should·move the Datalogger jumper to·SPI mode, and use different pinouts. But after that I'm lost as to what to do.

Does anyone have first hand information on connecting to USB devices?

Thanks, John

    Some of that will depend on what device to are connecting. I don't think the datalogger can be used as a host device.

    Search the BASIC stamp forum for the Vdrive, there was some sample code there, but maybe be a year or more ago.

    In general its easier to debug the interface in serial mode, and in most cases that throughput is adequate. Once your code is solid you can move to SPI.
