ROHMUSDC / Mbed 2 deprecated Nordic_UART_TEMPLATE_ROHM_SHLD1Update

This is sample code for interfacing ROHM's SENSORSHLD1-EVK-101 with Nordic Semiconductor's nRF51-DK Development Kit Host BTLE Board

Dependencies:   BLE_API mbed nRF51822

Fork of Nordic_UART_TEMPLATE_ROHM by ROHMUSDC

Code Example for ROHM Mutli-Sensor Shield on the Nordic Semiconductor nRF51-DK

This code was written to be used with the Nordic Semiconductor nRF51-DK.

This is the basic example code for interfacing ROHM's Multi-sensor Shield Board onto this board.

Additional information about the ROHM MultiSensor Shield Board can be found at the following link: https://github.com/ROHMUSDC/ROHM_SensorPlatform_Multi-Sensor-Shield

For code example for the ROHM SENSORSHLD0-EVK-101, please see the following link: https://developer.mbed.org/teams/ROHMUSDC/code/Nordic_UART_TEMPLATE_ROHM/

Operation

Ultimately, this code will initialize all the sensors on the Multi-sensor shield board and then poll the sensors. The sensor data will then be returned to the BTLE COM port link and will be view-able on any BTLE enabled phone that can connect to the Nordic UART Application.

Supported ROHM Sensor Devices

  • BDE0600G Temperature Sensor
  • BM1383GLV Pressure Sensor
  • BU52014 Hall Sensor

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)

Sensor Applicable Code Sections

  • Added a Section in "Main" to act as initialization
  • Added to the "Periodic Callback" to read sensor data and return to Phone/Host
