I want to set up my Teensy 3.1 to run a function when it receives a caps lock led signal from the PC. The driver software I'm using (controller mate on the mac) sees the 3 leds on the teensy keyboard and can send a signal to activate one, but I haven't been able to figure out how to listen for it in my arduino sketch. Does anyone know how to do this?
