jlcolemanmbed 0:5fa2b08cb3e0 2 * This program monitors the power on state, kill state and battery voltage on
jlcolemanmbed 0:5fa2b08cb3e0 3 * Woodstream mouse trap using the Multitech mDot and UDK2 development system.
jlcolemanmbed 0:5fa2b08cb3e0 4 * The power on state is monitored on the PA_4(UDK2 Pin D10)and the kill state is
jlcolemanmbed 0:5fa2b08cb3e0 5 * monitored on the PA_5 (UDK2 Pin D13) Digital Input Pins. The battery voltage
jlcolemanmbed 0:5fa2b08cb3e0 6 * is monitored on the PB_1 (UDK2 Pin A0) Analog Input. The status of these pins
jlcolemanmbed 0:5fa2b08cb3e0 7 * are transferred from the mDot LoRa to the Conduit LoRa gateway. The status is
jlcolemanmbed 0:5fa2b08cb3e0 8 * also shown on the USB Debug Terminal Window.
