Revision:
43:55e7bb4d9b60
Parent:
41:208af6be1869 
Simplified orientation change detection

Implement button press events

EVB Button1(left) for backend enabled state status (2 sblink = disabled, 3 = enabled)

EVB Button2(right) toggle bacend enabled status



LED Behavior

- LED solid when backend out of sync

- LED blinks on downlink
