Acc 05: Intertial wake up interrupt
This example shows how to manage the inertial wake up interruption.

Required Materials

1 x Waspmote 1 x MiniUSB wire

Notes

- When the inertial wake up interrupt is activated, a light movement of Waspmote will generate an interruption and wake up Waspmote. - This example can be executed in Waspmote v12 and Waspmote v15
