It is my considered opinion that there are no USB projects that are suitable for beginners.
hi sir...

actally i hd already strted blieving the same...after my hour long research on this field...

:)

but still i want to tell that m an electronics engineering student and really want to start with usb projects coz i have really big ideas related to cmputers that i want to fulfill...

what do you suggest sir..
thanks in advance...

It simply makes one LED (connected to port RA1 IIRC) to blink at 2 Hz rate and turns on/off another LED connected to port RA0 IIRC) in response to two commands implemented via to what is called "vendor specific requests".

It all started when Brad Minch, teaching at Olin, posted here http://www.microchip.com/forums/fb.ashx?m=89669 an implementation of four different labs (in C and Assembler) which are basic demonstrations of using USB to link a (very) simple device and a PC.

It is the sole LONG thread I ever read in any forum because I found the subject worth the effort.

Leon Heller posted on his site how to actually reproduce the first of them.

Yes, USB is more complex than complicated. After reading more than 80% of the basic as someone suggested I can say that the mambo jumbo was huge.

As you could read in the USB forum, I managed to get the four of them, up and running but it took time to wade through all the unknowns!

hi sir thanks for the url..

i have gone thru the frst post and it really seems interesting..though i havent understood much:D. its too complex for an undergraduate in electronics engineering...

yet with the help i hv receivd here..i think ill manage it....though its surely gonna take some time..

when m done with the theory part and m comfortable with this ill definitely gonna ask you guys again for 1 nice thing i have in my mind...

thanks again...
