https://devzone.nordicsemi.com/f/nordic-q-a/74141/configuration-of-pins-at-runtimeHello, I am writing the device tree for our custom board, which uses an nRF9160 SiP. This approach to configuring the hardware is new to me, since my experience is with micro-controllers where the hardware is configured at runtime.

Does Zephyr now allow for configuring GPIO&#39;s in runtime?<br />We have a pin that should be used as an ADC signal during most of the time, but before going into sleep mode we would need this pin to become a GPIO Input with enabled interrupt, so as to waking up the MCU (and then back again to ADC during &quot;normal mode&quot;).<br /><br />If this is not available and we use direct configuration of the MCU&#39;s registers, what are the &quot;special concerns&quot; in the device tree that we have to take in order not to mess up Zephyr usage of the pin?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/306833?ContentTypeID=1Mon, 26 Apr 2021 13:53:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c6293410-1805-4f5a-aa39-820ef51ea681Heidi<p>Hi!</p> <p></p> <div>Unfortunately, Zephyr does not have a runtime pin control subsystem yet. So if you want to change the device tree during run time, you&#39;ll need to use the HAL directly.</div> <div></div> <div>Best regards,</div> <div>Heidi</div><div style="clear:both;"></div>
