NuttX driver libraries for Rohm Sensors & Bluetooth LE

(NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. http://nuttx.org/doku.php?id=nuttx)

• Accelerometer KX122, I2C, SAD=0x1F
• Accelerometer KX224, I2C, SAD=0x1F
• Magnetosensor BM1422AGMV, I2C, SAD=0x0F
• Pressure sensor BM1383AGLV, I2C, SAD=0x5D
• ALS/Proximity sensor RPR-0521RS, I2C, SAD=0x38
• Hall Effect sensor BD7411G, GPIO
• Color sensor BH1749NUC, I2C, SAD=0x38/0x39

This repository contains the drivers for:

• Accelerometer KX224
• Hall Effect sensor BD7411G
• Color sensor BH1749NUC

This repository contains the makefile, kconfig and cxd56-sensors.c modifications to allow you to easily test these devices. However these files could be outdated compared to the Sony-provided files, and as such may cause you to lose other functionality.

Should you wish to use these drivers on a newer base, you need to modify:

• sdk/drivers/Kconfig and Make.defs
• sdk/bsp/board/Makefile
• sdk/bsp/board/common/src/cxd56-sensors.c

The actual driver files are located in:

• sdk/drivers
• sdk/bsp/board/common
• sdk/bsp/include/nuttx/sensors

The rest of the drivers are available on the Sony GitHub , and should come with the SDK.

For help regarding the installation of the Spresense SDK please refer to Setting up the Spresense SDK

1. Run the config and select the drivers and examples you wish to upload

• In the sdk folder, type tools/config.py --menuconfig

2. Save the configuration and run make
3. Upload the nuttx.spk to the board according to the instructions in the Flashing tutorial
4. When the system has booted, type help. This will show you the built-in applications, which should include the driver example you chose in the config
5. Type the name of the application in the NuttX shell, and the application should begin running
