The PIC 16C745 has it - but bear in mind USB is a GREAT deal more complicated than serial. MicroChip have application notes showing how to use it, plus full details (hardware and source code) for their new USB FLASH programmer, the PICKit1.charliez said:In the past an easy to use interface to a microcontroller is the serial port (RS-232) interface.
Nowadays, many devices have USB interfaces. How would I integrate the two? I haven't seen microcontrollers with built in USB ports.
