Calculator C / Keypad switching
« on: December 15, 2010, 05:15:06 pm »
Hi everyone,

I'm working on a project for the Nspire with Ndless 1.7, and I'd like to use the 84+ keypad. What I'd like to know is how the Nspire detects keypad removal (Keypad interrupt? GPIO interrupt? Hackspire doesn't really make this clear) so I can stop it from doing anything. I also don't get how the OS detects which keypad is currently installed.

Thanks!
