Although I've been in electronics about 25 years I really don't have any expertise in UBS or computer interfaces (I have an analog/RF background). I do have some experience with PIC devices however...
What I need is to have a PIC to directly interface with a PC so as to gather data and plot/print/calculate using the PC. I'd think this was a rather typical application. Yet I haven't a clue how to deal with the PC interface. It has to be a USB port (not an RS232). So I guess I need to know:
1) Do I need another IC in between the PIC and the USB connector? And, no, I haven't chosen a specific PIC device yet
2) Any "special" programming needed for the PIC?
3) Will I need a special "driver" put on my PC?
I think I have a handle on the PC software (going to use MS Visual Basic) which allows the USB to be set up as a "COM" port. I have done this before but I'm still baffled how it actually worked. lol In my case the PIC had already been programmed and I just used some VBA code to bring the data in but like I said I'm clueless as to HOW it actually worked...at least electronically.
Anyways, any help on how to get started would be greatly appreciated!
