I'm an newbee with USB communication (at least with microcontrollers). I want to created a device which can be connected to the PC through USB. The Microchip 18F2550 seems to be able to do this. However I cannot find any good documentation on the (external) hardware requirements for this. Do I just need the external pull-ups (maybe not with the internal activated) and then connect the D+ and D- to the USB port (some resistor as descriped in the datasheets for power and detection added if needed)???
Does anyone have a code example for the microcontroller and/or the PC???
ThanX in Advance
Alexander
