The same question has already been asked around a year ago by Carsten Groen in USB Custom class for RT106x and Custom USB class example/Idea for new sample for SDK ?
Since these questions are about a year ago I would like to know if there is any more information on that topic. I have to implement simple bulk transfers with two endpoints (IN and OUT) on RT1020. The SDK and SDK documentation still does not provide enough information on how to implement your own class or how to correctly use the provided API and it does not look like an example was added to the SDK as Carsten Groen suggested in his post.
Is there any new information/example regarding this topic which NXP could provide or could you give me guidance on which parts of the SDK examples I have to change / implement?
