I'm trying to use the scroll lock to enable or disable debugging. Hitting the scroll lock key on the pc keyboard lights the scroll lock led. It should therefore light the led on all attached keyboards through the appropriate hid messages. I'm basing my code on a merge of the 1-key keyboard and c64 keys projects and using the c64 led handling to trigger a key press being sent back to the host. In this case the L key. The concept will be that I open a text editor, hit scroll lock and will stream messages out (in this case all my nunchuck I2C debugging) as if a keyboard is disconnected. Releasing the scroll lock ends debug mode and gives me control back
First problem was my laptop remaps the scroll lock on my external keyboard so I've shifted to caps lock. Second is it doesn't work - I press the key but get no output
I've attached the main.c and header if anyone is willing to take a look
