https://devzone.nordicsemi.com/f/nordic-q-a/66335/where-is-the-saadc-documentation-what-driver-should-be-usedHi All, the sdk17 documentation has the sad adc included (sad because a 12-bit adc turns out to have 9 effective bits and then with +-3% error on top of all that effectively being a 5-bit converter!?!). But which functions are to be used?

I believe it intended to link to this file, or something similar:&nbsp;<a href="https://github.com/NordicSemiconductor/nrfx/blob/v1.8.4/drivers/include/nrfx_saadc_v2.h">https://github.com/NordicSemiconductor/nrfx/blob/v1.8.4/drivers/include/nrfx_saadc_v2.h</a></p> <p>Any of the driver APIs are fine to use in nRF5 SDK. The legacy layer (nrf_drv_saadc_*) is the using nrfx_saadc_v1 implementation between the legacy layer. This is the API used in the SAADC example in the SDK. You can post this example to nrfx_saadc_v1 driver by following the instructions in&nbsp;<a title="Migration guide for nrfx drivers" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/nrfx_migration_user_guide.html?cp=7_1_2_7">Migration guide for nrfx drivers</a>, but this will not give you any new features or increased performance.</p> <p>The nrfx_saadc_v2 driver API is a complete rewrite of the SAADC driver, to fix some known issues, and provide even more flexibility than the old driver. You can find a link to a few examples in the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/migration.html#migration_drv">SDK 17.0.2 migration guide</a>, and I also added a couple of similar examples to <a href="https://github.com/NordicPlayground/nRF52-ADC-examples">this GitHub repository</a>.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
