For Shimmer2/2r, the user button is pulled down on the Shimmer board. Pressing the button will result in a high signal that can be used as a polled or interruptible signal on Shimmer applications. For Shimmer3, the user button on the External Expansion board is tied to P1.5 of the MSP430 (GPIO External). - Page 12 Copyright © Shimmer 2016 Realtime Technologies Ltd External Expansion Board User Guide All rights reserved Rev 1.6...
