Kinetis USB detailed hardware manual

[izmile]

Hello folks,

I am a new kinetis user. I was wondering if there is a detailed hardware description of the USB peripheral used in Kinetis processors. I got the USB OTG/Host/Device stack user manual and the reference manual of the processor (K60) that I am using. However, I believe it does not cover all the details. There are lot more things done in USB_LDD code, than what is given in the reference manual. Any pointers would be of great help.

Thanks,

Hi, Ismail

What class you want to use? There are some example projects in Freescale USB stack 4.1.1. It can help you to get a start. After you install, you can find in folder path C:\Freescale\Freescale USB Stack v4.1.1\ProcessorExpert\Examples.

Best Regards

Paul

Hi Paul,

I would like to implement a composite device that has 5 ccid smartcard readers and 1 hid interface. I believe I need to write my own class drivers, although I could use the hid drivers from the example projects. However, I would like to know the internal working of the USB peripheral and the things done in USB_LLD code from a USB device perspective. The reference manual just touches up on these details but it is not giving a full description of the how the USB peripheral works.

I am sure there would be some resource available but it may be internal to FSL. Anyway, I thought it is worth asking.

Thanks,
