Temperature Sensor implementation

[hiteshk014]

Hi,

We are working on Nrf Connect SDK1.8.0, we want to interface temperature sensor Ti - LM75B, which interfaces I2C protocol

We need to know more about sensor implementation using i2c, 

can you please share any reference implementation of peripheral using I2C.

Thank you,

Regards,

Hitesh

Hi,

You can find lots of Sensor Samples in the Zephyr repository of nRF Conenct SDK. There is already a driver for LM75, but I can't see any ready-made samples for this sensor.

I would recommend you to start out with one of the existing I2C sensor samples, and modify it to work with your LM75B sensor.

Best regards,
Jørgen

You can look at the ADT7420 sensor sample. This has overlays for nRF52832 DK.

Hi,

Did you manage to resolve this issue, or do you still need assistance from our end?

I tried running your application, and I can confirm that it does not seem to work correctly on my end either.

Best regards,
Jørgen
