Well there's a simple answer to that :) http://www.ftdichip.com/FTProduct.htm Or the datasheet if you like: http://www.ftdichip.com/Documents/ft245r09.pdf If you look at the homepage there are samples for drivers and customisations etc. But is actually is an 'serial' device not parallel, but as it is using USB I don't see that that should hinder the troughtput to anything considered 'to slow' for an PIC. /Tony -- http://www.piclist.com hint: The PICList is archived three different ways.
