Several people on this list have conducted reviews etc. of the available US= B tools for PICs, and referred to the bugs in the vendor supplied USB softwar= e stack(s). Internet searches seem to indicate that there was no recent (post 2008?) activity in this domain. I am aware of Xiaofan's blog, James Newton'= s piclist.com resources, and Microchip's own resources for USB development. Are there any more such recent resources out there? This is in the context of the need for a simple boilerplate code set which allows a simple hardware validation application to be built (and later deve= loped further). A HID device would be ok but it does not have to be that, any oth= er reasonably simple device would be a candidate. My intended target for this project is PIC18F14K50 or similar. thanks, -- Peter --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
