-============================================
-EFM32-TG-STK3300 Examples lightswitch README
-============================================
-
-This is a small example program for GPIO input and output, and how the device
-can be configured to use minimal power (although the example is merely
-scratching the surface of what is possible powersaving-wise).
-
-It's intended for the EFM32-TG-STK3300 eval board. It turn the User LED on when
-PB0 is pressed, and off when PB1 is pressed.
-
-Various implementations are offered (-busywait, -interrupt), and can configured
-in lightswitch.c.
