…nfiguration On nrf54h20 there are additional analog pins (AIN8+). When differential mode is used they must not be mixed with AIN0-AIN7. Add build time validation which detects if configuration is invalid. Upstream PR #: 87405 Signed-off-by: Krzysztof Chruściński <[email protected]>
…vref_mv Sample is reading vref-mv property to get reference voltage and then if reference source is set to ADC_REF_INTERNAL this value is overwritten. If vref-mv property is provided then it should not be overwritten. Upstream PR #: 87405 Signed-off-by: Krzysztof Chruściński <[email protected]>
…nfiguration AIN9 source needs special handling (all from AIN8-AIN14). Conversion result needs to be scaled up by 3.6 additionally to gain and reference voltage. In order to achieve correct value in the sample vref-mv is used as reference voltage instead of predefined internal reference source.
