USB to SERIAL Converter using PIC

usb to serial +pic

Is it possible to have a USB to SERIAL Converter using PIC micros? like 16F628?

Yes. But why bother? Generic convertor chips are cheap. Besides, writing the virtual serial port driver for your own convertor is no trivial task.

Added : On 2nd thought, the 16F628 may not even have enough IO pins to interface any USB device controller IC.

Try USB-RS232 converter from FTDI company.

Or, try to use this ucontroller frm microchip: PIC18F4550
"... the availability of three serial ports: FS-USB(12Mbit/s), I²C™ and SPI™ (up to 10 Mbit/s) and an asynchronous (LIN capable) serial port (EUSART)"

Ow..I never thought it's complicated as that..
I was considering PL2303 since FTDI is not available in my place..
but the PL chip has a bad impression in me..I bought a USB data cable for my Nokia phone and it was not working the chip inside is PL2303, so I think PL chips are not that good..

the less difficult thing is to buy a dedicated chip and use virtual port driver...
