I have the smaller slower version of the MK22F chip set on my custom board the MK22F12810 chip. I'd like to get a USB stack running on this chip, but there isn't a usb platform build for this chip. I've successfully used the FRDM-K22F board and ran a simple keyboard hid usb application. Is there a way I can modify the MK22F51212 platform, so I can build and run the same keyboard demo on the MK22F12810 chip? Or is there another approach I should be doing to get this kind of application running?
Hi
Take a look at

- composite devices http://www.utasker.com/kinetis/USB_Device.html
- User's guide http://www.utasker.com/docs/uTasker/USB_User_Guide.PDF
which includes USB stack which is compatible with all K22 parts (just needs SIZE_OF_FLASH and SIZE_OF_RAM set accordingly and adapts itself to the part in question).
Also the USB operation can be simulated in Visual Studio (including interrupt and DMA operation) for learning and operation reviews in critical applications.
