Where are the SDK application notes?

scottm — Sat, 06 Apr 2019 02:51:47 GMT

I'm setting up USB suspend/resume on a K22F part using the SDK USB stack, and I searched through all of the documentation that comes with the stack but there's no mention of USB_DEVICE_CONFIG_LOW_POWER_MODE, which seemed to be the relevant option.

Googling USB_DEVICE_CONFIG_LOW_POWER_MODE brings me to AN5385, which is exactly what I needed. The route to discovering it was less than ideal, though - even finding that the config parameter affected suspend/resume required reading through the ISR code.

Are there other app notes related to the SDK? Where would I find them? If I go to the documentation section and filter on app notes for Cortex M MCUs I get a total of 30 documents, and this isn't one of them. In fact Google doesn't find any pages anywhere that link directly to that document.

The MCUXpresso SDK section has a documentation tab that has zero app notes. This app note has been out there 2 1/2 years and I've never encountered it, and it's super frustrating knowing that documents like this exist and there's no obvious way to browse for them, and when you find one there's no way to tell where it lives on the NXP site.

Thanks,

Scott

Hi Scott:

I would suggest you search document from the top right corner of NXP website. Input your key words.

There are two demos about usb suspend/resume in SDK, I hope it helps

boards\frdmk22f\usb_examples\usb_suspend_resume_device_hid_mouse

boards\frdmk22f\usb_examples\usb_suspend_resume_host_hid_mouse

Hi Daniel,

I think I didn't explain my question properly. My question is how would I browse the site to find this and whatever other application notes exist for the SDK? What section of the website does AN5385 exist in?

Thanks,

Scott

Hi Scott:

I search application notes from below link.

Search Results:

If I input key words： usb suspend resume, and select Document type as application note, I can see AN5385 on the search list.

Or you visit below link .

Arm® Cortex®-M4|Kinetis® K22 120 MHz 32-bit USB MCUs | NXP

Hi Daniel,

I think I'm still not making myself clear. How would one find ALL of the application notes for the MCUXpresso SDK, including this one?

To put it another way, using AN5385 as an example, how would you browse the site to locate it? Not searching by keyword, but actually finding the documentation section to which it belongs?

Thanks,

Scott

Hi Scott:

Let's take MCU k22f120 for example, please see below pictures.

Then you will get all application notes involved in K22f120. unfortunately AN5385 is not in result list.

Yes, that is the problem. Under what device would I find that app note?

Just checking in again - have you been able to find an answer on where AN5385 lives, and if there are any other SDK app notes hiding out there?

Thanks,

Scott

Hi Scott:

Just an information that this application note AN5385 is displayed now in the K64_120 documentation tab. Thanks again for your feedback.

Hi Daniel,

Thanks, that's an improvement. Since I'm using the K22_120 series, what would you recommend for finding other relevant documentation like this? Is the K64_120 tab likely to have more app notes that are applicable to the K22_120 that aren't in the K22_120 section? Are there any other families I should be browsing as well?

Thanks,

Scott
