Reading X, Y & Z Values From Accelerometer connected to nRF52840 DK

[Jaz]

Hi, 

I was wondering what example to use if I have an accelerometer on a breadboard connected to the nRF52840 DK via TWI/SPI and the DK connected via USB to my Mac? I want to obtain the X, Y and Z values from the accelerometer but the SPI slave and master examples don't mention how to do this. 

Thanks.

Hi Jørgen, 

Thanks for your reply. I'm wanting to use the MC3672 accelerometer who's data sheet I've attached: https://mcubemems.com/wp-content/uploads/2016/12/MC3672-Preliminary-Datasheet-APS-045-0018v1.0.pdf

I'm using the EV3672 board which the accelerometer is mounted on so maybe this data sheet will be of more use: https://media.digikey.com/pdf/Data%20Sheets/MEMSIC%20PDFs/EV3672A+B%20QSG_Demo.pdf

I'd be extremely grateful if you could point me to where I can find out about how two configure the sensor for the accelerometer, I need to figure out how to obtain these values by the end of today and I don't know if I'll be able to so I'd really appreciate your help!

Hi Jørgen, 

Thanks for your quick reply. If I run the .c and .h files you linked in Segger Embedded Studios with the DK connected, will I be able to read the sensor values or do I need to implement some other code as well? Thanks.

You need to implement the functions to initialize + read/write registers over SPI/TWI on the nRF52 platform. There is a user-guide in the repository.

Thanks so much Jørgen, you helped a lot! I hadn't come across this user-guide before.
