MCF52210 USB Question

[junkers13]

Hi I just have a quick question.  Is it possible to communicate through USB from a PC to the microprocessor.  Say I wanted to send text through hyper terminal using USB, is it possible?


Thanks,

I have a driver that does just that -- it emulates a USB FTDI serial port, and the PC drivers automatically load from microsoft.com so you can talk to the MCU.  It also has terminal line editing and a small history buffer.  You can see the source code here:

You'll need the low level usb driver and the upper level ftdi driver.  I'm eventually going to post a full project with dual-mode (host/device) USB functionality, but for now the individual files are there.  I'm happy to help you get the sources running if you want to e-mail rich@testardi.com.

And just to follow up, I posted an example skeleton project (skeleton.zip) on the webpage above which runs an FTDI serial port and simple command line interface on the M52221DEMO board, along with built-in administrative commands to perform flash cloning over ezport to a target board as well as S19 file firmware upgrading over the USB.  If you run it and connect with HyperTerminal and press <Enter>, you'll see:
