MCF5329 USB CDC UART

Reibax — Thu, 11 Sep 2008 17:13:22 GMT

I am working on a MCF5329 based board, an I really need it to work as a Virtual UART when connecting it to a PC through the USB cable.

¿Is there any free stack/driver that I could use to this end for the MCF5329? I've downloaded CMX's stack for the 5222x family, but I am finding it really hard to port it to this microcontroller.

If none of the above is possible ¿Where can I find a tutorial that will teach me how to write a simple implementation that will help me?

Thank you very much for your time and help.

Hi,

I've written virtual serial ports for the 52221 but never the 5329 -- they look very different.

The website I found the most useful for USB protocol information was:

http://www.usbmadesimple.co.uk/ums_1.htm

For information on the 5329, have you seen this:

Thank you very much for the info.

I've alredy had a glimpse at the sites and they look very interesting. I will be reading them in detail on the following days.

Anyway, if anybody has code that would help me save some time in manually writing everything, I would be very very grateful.

If you have the memory for it you might consider ucLinux. I am using the gserial module for virtual com port communications with a custom board based on the 5329evb.
