MPU6050 sensor for nrf5340pdk board?

[zephyros_user]

Hi,

I wanted to use my nrf5340pdk board with a MPU6050 sensor.

I am using the zephyr os and they provide an example project for this sensor. The example project provides:

• main.c
• CMakeList.txt
• prj.conf
• sample.yaml
• and also a folder called boards with nrf52dk_nrf52832.overlay.

Does this mean, that I can only use the MPU6050 sensor with the nrf52dk board, or can I create a new .overlay file for my nrf5340pdk board?

If yes, how does this file has to look like?

Thanks for your help!

Hello! 

You should be able to use this sample with your nRF5340. Make sure to connect the MPU6050 sensor to the correct I2C pins, and rename the nrf52dk_nrf52832.overlay to  nrf5340dk_nrf5340_cpuapp.overlay


Also, make sure to read the nRF5340PDK User Guide to ensure correct pinout, and we also recommend going through the nRF Connect SDK tutorial if you are new to NCS and "Working with nRF5350" from our NCS documentation

Kind regards,
Øyvind

Hi,

thank you for your quick response!

I renamed the nrf52dk_nrf52832.overlay to  nrf5340dk_nrf5340_cpuapp.overlay but unfortunatelly it is still not working.

I read different information about the connection of the sensor with the I2C pins... Here in the forum, it was said to connect SCL and SDA with P1.02 and P1.03, but in the user guide here (https://infocenter.nordicsemi.com/pdf/nRF5340_PDK_User_Guide_v1.0.pdf) I can not find these pins. Can you tell me which pins are the correct ones for connection with I2C?

Thank you!

Hi,

okay thank you. Unfortunaltelly, it is still not working... I did not do any changes to the code so far.

How does your prj.conf and the sample.yaml file look like?

And did you do the adjusting settings to the board to enable I2C? In the User Guide of the nrf5340pdk board it says that you need to shorten SB32 in order to permanentely enable I2C, do I need to do that?

Best Regards!

Is it possible that you provide me your sample? So that I can test, if this configuration is working for me?

And does it make a difference in nrf5340pdk and nrf5340dk?

Thank you!

Did the sample you received in #262880 work? 

I did no other changes other than nrf5340dk_nrf5340_cpuapp.overlay I pasted in my last response.

Can you please share the working project files?
