Keyboard: Unable to get mod keys w/o tapping a regular key #29

Open richjamrosz opened 3 years ago

richjamrosz commented 3 years ago

I'm using 2 Seeed Xiao's communicating via Serial1, one of them programmed with the 'GetModifiers" example from arduino.cc, the other doing simple serial passthrough to Serial Monitor. The mod value only changes when a regular key is tapped ex. 'a'.

WIth the windows key being a mod key, it makes it impossible to tap that key to open the start menu. Also, in general, I would like to pass through modifiers as they are pressed and released, just like if the keyboard was hooked directly into a computer. Is there some method that does this already that I'm missing? Is it possible to get mod keys to fire the same as basic keys?

Have you had any luck with this issue? I am having the exact same problem where GetModifiers only updates when a regular key is pressed. I need it to be able to detect just modifier changes in the cases where a modifier is combined with a mouse press.
