MQX USB Device stack

[admin]

I am using MCF52259 microcontroller. I want to implement USB device in my project and I want to use USB device as Virtual COM port. I have following questions.

1. Is it possible to implement Virtual COM port using MQX USB device stack?

2. Is there any sample code to implement Virtual COM port using MQX USB device stack?

3. If I am able to implement Virtual COM Port in my hardware then where will I get virtual COM drivers for PC?

Thanks.

Hey i too am working on MCF52259 and trying to implement USB CDC device. Did you get the answer of how to do it using MQX?

Hi Prajwai,

Did you try the lastest MQX release and run the following demo:

C:\Freescale\Freescale MQX 3.8\usb\device\examples\cdc\virtual_com

Hi

I believe that there is CDC device support in the latest MQX version.

It is probably easiest to use usbser.sys, which is available on every Windows PC. This allows a virtualCOM to be used without any extra work on the PC side.
