USB HID Interrupt OUT for Kinetis K21.

Hi all,

Is there a reason why processor expert (HID CLASS module) does not allow adding a second interrupt endpoint for host to MCU transfers?

I made a non PE project from the generated stack and implemented the interrupt OUT endpoint but running into problems. Has anyone successfully implemented it for the K21?

Thanks,

ajohn

Hello,

There is released a new solution of USB components (fsl_usb_device_hid_class, fsl_usb_device_msd_class, fsl_usb_framework, fsl_usb_descriptors) that is available in KDS 2.0.0 (with installed Kinetis SDK 1.1.0 Eclipse Update).

If you want to start a development of an application based on fsl_usb_.... components, you can use the Processor Expert Kinetis SDK USB Stack Integration User Guide that is available as a part of the help.

You can open the guide by the following way in KDS 2.0.0 (you must have KSDK 1.1.0 Eclipse Update installed):

- Open Component Library window and find fsl_usb_descriptors component.

- Open the context menu of this component (click by right button of the mouse) and select Help on Component item.

- In the Help window, open the fsl_usb_descriptions page

- The fsl_usb_descriptors help page (General Info tab) contains link to the user guide "USB stack Processor Expert integration documentation" at the bottom of the page.

 

Best Regards,

Marek Neuzil
