Hello again everyone!
I've been doing a bit of reading and I've tried a couple of things but can't seem to get properly started.
My end goal is to be able to press capslock (or emulate a capslock press) on the host device and have that sent directly to the Espruino Pico which I've got in USB HID mode. I'd like for the Espruino to then be able to be recognise that command and then I'd activate a function to turn on one of its LEDs. Then behave as one would expect and adjust all characters sent to the host as if the Caps Lock were pressed on an actual keyboard.
My understanding is that commands like setleds can be used to manipulate the LEDs on Keyboards and I this would be a cool way to do it but I'm unsure how to get the Espruino to receive/understand this.
I'm very keen to avoid writing a script that would simply sends one of the echo commands to the espruino upon a capslock press. Though I would not mind writing a script that realises a caps Lock has been pressed and sends a setleds command.
TLDR: How do I get the Espruino Pico to understand a setleds/Caps Lock command from the host as if it were a real Keyboard?
