PIC16F877 and USB

Hi,
Is it possible to interface PIC16F877 to a computer using USB instade of RS232? How "hard" is it? Any examples i can take a look at?

Cheers
Tom.

See the 16F87x Datasheet

That helped a lot, thank you.

i Want to do this if you have some information please send me.
Thanks.

Hi,

I'm quite new to PIC / PICBASIC and USB.

I've been using the PIC16F877 and the DLP-USB245M unit to achieve PIC to PC communications via the USB port. The DLP-USB245M is really easy to use and all the 'nasty USB' code is done in a virtual comm port software which they supply as a download from their website. You just treat it as if it was another MSCOMM port in your code (I'm using VB6 by the way).

I hope this helps - GOOD LUCK!! :-)

OR buy a USB-to-Serial converter. If you don't want to mess with the SMD soldering and if it's for a single ended product, that's a fast solution.

On another hand you can still use a USB PIC like the PIC18F4550. Using Mecanique EasyHIDMaker save you many developpement, reading hours and so on.

FTDI are great so far. I know it exist some other.. that i don't remind.. OOps! For sure there's some user here who remind.

Good luck!
