I need to control a mouse pointer with two potentiometers. No buttons needed. I have tried to adapt the USB firmware from Microsoft using the 16c745 but my experience and understanding of this is limited. If I use two of the ADC channels for the pots, can I control the pointer this way? How about substituting a 16F818 or 916 (or anything I can reprogram ) for the 16c? I would like to use a usb connection for this. Any suggestions? Assembly language would be best for me Thanks BobL -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
