Unable to find samples in NCS/NRF SDK v1.5.1 and missing things like nrf_drv_twi.h

[jansens]

As described in the title I'm unable to find the examples such as twi_scanner that the documentation says is found in /NCS/examples/peripherals. Here is a screenshot of my SDK directory. I have searched high and low for these files in here, installed previous versions of the SDK, etc. No idea what's going on with this or what I'm missing, I did everything according to the tutorials, documentation, and instructions. I really need to find the provided stuff in the SDK like nrf_drv_twi.h, etc but tons of stuff is missing it seems. What am I doing wrong or missing???

Hi,

I think part of the problem here is that you are mixing two different software development platforms.

There is the legacy nRF5 SDK and there is the new nRF Connest SDK:
https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk.html

The two platforms are architectural different, and can't be mixed (even though they do share some common lower layer nrfx hal, the drivers are not the same).

If you are interested in nRF5340, then you need to look at the nRF Connect SDK, and the application samples you can find there:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf5340.html#application-samples

In terms of TWI (I2C) scanner example you may find this useful:
