How to use Adafruit sensors with nrf52 through TWI/I2C?

[ndarkness]

Hello,

I would like to make use of an Adafruit sensor Adafruit_TSL2591 connected to my nrf52 through the TWI interface. I have seen the example TWI master device, in that example the sensor is addressed directly, however this adafruit sensor has already implemented a library in arduino ( but is in C++).

Would it be possible make use of such as an example (TWI master) and combine it with the adafruit library?

On the other hand, how can I compile a C++ project in the nrf52 sdk, I see that all the examples are in C so I expect some issues while compiling. Is there a makefile for compiling in C++ ?

Thanks in advance EDIT attached library MPU9250.cpp MPU9250.h

It should be possible to use the library written in C++, but you will have to integrate the TWI driver into all functions using TWI. The Makefiles in SDK 12.2 should support C++ file. Just try it out, and I will help you if you are encountering any problems.

Hi Jorgen, I will try to do it and come back to this post. Thanks

Hi Jorgen, I have tried it but I could make it work, I just took the TWI master example and I added this library(attached in the main post) for a mpu9250. I couldn't make it compile with SEGGER Embedded studio :(

I did not try with Segger Embedded Studio, but I have tried this with the Makefiles in our SDK. Which errors are you getting when trying to compile? The library you uploaded is for Arduino boards, you need to edit it to use the TWI driver to work with nRF devices.
