https://devzone.nordicsemi.com/f/nordic-q-a/85521/ir-receiver-configurationHi, I want to use a TSOP IR receiver on a custom board for sending different commands to my device through a remote controller. for example, if I use a Samsung TV controller, I can do the different tasks by pushing every key on the controller if I canen-USTelligent Community 13Tue, 08 Mar 2022 11:56:38 GMThttps://devzone.nordicsemi.com/thread/356860?ContentTypeID=1Tue, 08 Mar 2022 11:56:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:038f9245-9562-4a02-a096-ab36af4ea423Kenneth<p>There are different ways this can be solved, so I suggest you continue to look for what others have done, and follow the one you are most comfortable with. Personally I would connect a IR receiver diode to a GPIO of the nRF52. Then typically the receiver diode will output logic high when there is PWM signal present and logic low when there is no PWM present. Then you only need to measure the timing between high and low transnition to know when the PWM is active and not. You can then measure the input using an&nbsp;internal timer to receive and decode the signal. The reason I suggest this way is because you avoid measuring the ~38kHz PWM signal, you only measure when the PWM is off and on.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
