Code used for Sensor Expo 2016 - Balloon Game. More details can be found here: https://github.com/ROHMUSDC/ROHM-SensorExpo2016-Pressure-Sensor-Demo/
Dependencies: BLE_API mbed nRF51822
Fork of Nordic_UART_TEMPLATE_ROHM_SHLD1Update by
ROHM Balloon Game Demo Code featured at Sensors Expo 2016
This code was written to be used with the Nordic Semiconductor nRF51-DK.
This Code allows the user to configure two known pressure distances and save pressure readings onto the application. Then it will automatically extrapolate these values and allow the user to see the height of the board. When connected to a balloon, greater heights can be achieved and the board will return the current height of the board.
