Digikeyboard needs implementation of NumLock/CapsLock/ScrollLock status #33

Open Akasurde opened 8 years ago

Akasurde commented 8 years ago

As title suggest, in one of my project I need to detect status of Caps Lock button on host machine in digispark.

Currently, DigiKeyboard library doesn't implement such functionality. I am newbie in USB stuff so not aware how to implement such functionality.

I think it is something related to "USBRQ_HID_SET_REPORT"

Hey. To enable/disable caps lock, just type into your code : DigiKeyboard.sendKeyStroke(57);

Hope it helps !

I need to get status of NumLock/CapsLock/ScrollLock keys from USB HOST to digispark. My use case is I want to perform some operation on DigiSpark (like blink LED) on USB host presses any of above keys.

Oh, okay, I dunno that. Sorry for misunderstanding. But I think an HID device can't get some info on the computer...

Via usbHidReportDescriptor Digikeyboard.h tells the host to not send reports for status LED updates.

This is probably done due to the limitations of the currently used USB driver usbdrv.h.

More info on the usbdrv.h
