Understandable, good to know that you got it working!

Best regards,

Hi Michal, sorry I missed this reply. Some of the example code on the DevAcademy had some errors, but I was able to get i2c working fine with my project. I usually use other manufacturers, so this is my first PCB design with Nordic, under a tight schedule (just restarted today after a delay) - so hopefully the design will work first time!

Yes, it has been unfortunately removed (not by us) in the zephyr version used in NCS 2.4.0, but since you were using 2.3.0 in the original post I have assumed that you are only using that version. I think it should work in 2.4.0 if you just copy and paste it though.

This sample should be pretty straightforward, and you may supply it with the higher-lever functions from the aforementioned I2C API.

Also, please tell me what you would like to see in a pure i2c example, since I would like to provide one.

Best regards,

Michal

Edit: Just noticed the example IS in the 2.3.0 directory, but removed from 2.4.0. Not sure why it's building with 2.3.0, but I'll just remove 2.4.0 to ensure there's no conflict.

Thanks, I have the nRF Connect IDE, and that sample is not in there. In fact, there is no pure i2c example at all in any samples (just drivers for specific sensors). This is with version 2.4.0. I don't generally use Nordic, and have just picked up a legacy project that I need to get working well enough for a proof of concept so I can just bit-bang i2C in software to get it working. I'll probably change to a more familiar manufacturer to get it working in hardware after this prototype. Thanks!

The code is in the nRF Connect SDK that I assume you have in C:/ncs/v2.3.0/ as shown on your screenshot.

This sample should be in zephyr/samples/drivers/i2c_fujitsu_fram inside your folder. I have been using it personally for trying out things with I2C.

I am also thinking about writing a basic I2C sample myself, but I am not sure when that will happen.

I would recommend using our nRF Connect for VS Code IDE/extension and for general getting started with NCS we have the Nordic Developer Academy, specifically the nRF Connect SDK Fundamentals course.

You should also look at Zephyr's I2C API for more different functions.

For more low-level support there is the nrfx TWI driver.

I don't recommend using nRF5 IDE for any new project as it is not supported anymore and does not get any updates.

Best regards,

Michal

Thanks, there's no actual code at that link though (the sample is also not in the installed examples). I've been checking and it seems the Zephyr based NRF Connect doesn't really support low level peripherals like i2C, as they're trying to abstract it all into manufacturer-supplied libraries and blobs. That's why there are no examples for the IDE. So the older nRF5 IDE seems better for low level work.

Failing this, I'll probably just bit-bang i2C and ignore the lack of peripheral support.

Hello,

I would recommend checking out the I2C Fujitsu FRAM sample.

Best regards,

Michal
