How to query USB keyboard status LEDs?

laszlomonda — Sat, 28 Oct 2017 16:00:38 GMT

Hi there,

I'd like to query the state of Caps Lock in our open source keyboard firmware.

According to my knowledge, this state is sent in the set report request of endpoint 0, so I assumed that it resides in the report buffer of this code block. I dumped the value of the buffers of both clauses but none contained keyboard LED state.

I'd appreciate any help. Thanks so much in advance!

Hi,

although this project use NXP MCU, but it is not owned and supported by NXP. You can submit your question to related community.

I know that, since this is our project, not an NXP project. :smileygrin:

With all due respect, I hardly think there's any other more relevant community than the KSDK thread.
