I am trying to build a USB based Infrared Communications Port. I am using the PIC16C745. I do not understand how I will construct the device and program it in a way that I won't need to write any drivers for the USB on my own afterwards. Any suggestions? _________________________________________________________________ Express yourself with cool emoticons - download MSN Messenger today! http://www.msn.co.uk/messenger -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
