I've made something that's basically equivalent to the quadrature encoder input example in the SX/B help file (see attachment), except I'm using an optical encoder that needs 5volt power. Unfortunately I am new to microcontrollers and could use some help.

 

What I would like to do is have a simple momentary pushbutton that I can use to turn on and off this device. I want to use little or no power when off because this will be running on battery power. From both a hardware and software standpoint, how can I have this thing kill power to the LED display and encoder when a pushbutton is pressed? I was thinking about using the SLEEP function somehow and using an output with a transister to power my components.

 

Does anyone have any examples of how this would be done?

 

Thank you for any help.
