Any examples of KwikStik bare metal USB (CDC) using processor expert?

Spikey_Mikey — Tue, 24 Apr 2012 03:57:56 GMT

I have CW 10.2 and am trying to get a USB (CDC) project up and running on my KwikStik. I want to stick to a bare metal project and be able to use Processor Expert for several other peripherals that I am using. I tried to pull in the CDC .project from the USB stack V3.2 as a starting point, but was unable to get the project to import. Lots of files were missing. Does anyone have an example project I could use?

Thanks,

Mike

Hello,

I was informed that there is being finished a new release of the FSL USB stack (v4.0). It will

include a CDC Processor Expert example. It should be available at the end of May timeframe at http://freescale.com/usb .

I have what you want.

I am also working on a version that is the entire stack in one file!

Oops. I missed the processor expert requirement. I do have a project where you can simply dump in a folder and get what you want.

Hello,

I managed to get build Processor Expert versions of the Freescale USB CDC stack.

http://mcuoneclipse.wordpress.com/2012/05/04/usb-cdc-goes-medical/ has added MCF51MM256 support, and the attached version supports Kinetis K40 and K60.

The TWR-Kinetis K60 adn TWR-Kinetis K40 projects work as expected (there is still the fundamental issue (in the stack?) about sending/receiving a lot of data).

However, for the KwikStik one I only can send data to the Kwikstik, but not back to the host? I'm not sure if this is a problem of my board, as there seems to be many revisions of that board, and I have Ver 5 one.

Hope this helps,

Hello,

the problem with the KwikStik (was only able to receive data, but not to send) has been fixed with attached .inf file.

Thanks for the responses. I will be busy this week... I noticed that 4.0 is out!

Hi Eli

I have been looking for a USB CDC example without processor expert with mqx if possible. You mentioned that you had worked this out. Do you have anything you can share or even a link to an example? I haven't found much of help so far.

Thanks

Robert

Fix in my case is:

follow errata and increase C34 capacitor to 4,7uF. :smileyhappy:
