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.
Additional information about the ROHM MultiSensor Shield Board can be found at the following link: https://github.com/ROHMUSDC/ROHM-SensorExpo2016-Pressure-Sensor-Demo/
For code example for the ROHM SENSORSHLD0-EVK-101, please see the following link: https://developer.mbed.org/teams/ROHMUSDC/code/ROHMSensorShield_BALOONGAME/
Operation
See Github Repositoy for additional information on how to operate this demo application.

- * Description: This Applications interfaces ROHM's Multi-Sensor Shield Board with the Nordic nRF51-DK
- * This Code supports the following sensor devices on the shield:
- * > BDE0600G Temperature Sensor
+ * Description: This Application interfaces ROHM's BM1383AGLV with Nordic's nRF51-DK
+ * This Code supports the following sensor devices:
* > BM1383AGLV Pressure Sensor
- * > BU52014 Hall Sensor
- * > ML8511 UV Sensor
- * > RPR-0521 ALS/PROX Sensor
- * > BH1745NUC Color Sensor
- * > KMX62 Accel/Mag Sensor
- * > KX122 Accel Sensor
- * > BM1422GMV MI Magnetometer
- * > KXG03 Gyro (Currently Unavailable as IC hasn't docked yet)
*
- * New Code:
- * Added Variable Initialization for utilizing ROHM Sensors
- * Added a Section in "Main" to act as initialization
- * Added to the "Periodic Callback" to read sensor data and return to Phone/Host
- *
- * Updates from SHLD0 to SHLD1:
- * > Pressure Sensor Changes: Fixed Register Map Changes for BM1383AGLV
- * (See Pressure Sensor Datasheet for more details - TEMP and PRES output switched)
- * > Added new #ifdef section for Magnetometer
- * > Changed Gyro Device Address (7bit addr now 0x4F, not 0x4E)
