Just curious if anyone has used one of the pics with usb to create a usb to serial bridge? I know the usb-232 are fairly cheap but I really need a much more compact design. I googled and found lots of these but all seemed to use a FT usb converter chip. I was looking at the 18F's with USB 2 and pondering if it could be done with just a pic. so has anyone done it seen it? Has schematics to share? ;-] Dave. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
