https://devzone.nordicsemi.com/f/nordic-q-a/25398/intersection-of-pdm-module-with-twi-moduleDear Nordic team, I have a running NRF52 with a firmware based on the freeRTOS demo. To this demo I added the PDM Support Module and the TWI Module. As soon as both sensors are available, I get very random intersections and the TWI Module stops workingen-USTelligent Community 13Wed, 27 Nov 2019 14:57:41 GMThttps://devzone.nordicsemi.com/thread/222408?ContentTypeID=1Wed, 27 Nov 2019 14:57:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f0fa6275-0708-4088-9046-76d4d99d4f7bOr<p>Have you found a solution ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/100110?ContentTypeID=1Thu, 05 Oct 2017 08:42:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2f9e6217-6522-4826-8b20-51ffcd6248a3J&#248;rgen Holmefjord<p>You can upload a zipped version of the project by clicking the edit button on your original question.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/100109?ContentTypeID=1Mon, 02 Oct 2017 11:03:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cae0b9a1-5d23-436a-ad80-28fb8e62e8b4StefanNoll<p>I added the information of the pins, the complete project is quite big to post it here, I could send the code directly.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/100107?ContentTypeID=1Thu, 28 Sep 2017 09:09:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ef729b09-c445-47e4-aefc-6edc7f1a4faaJ&#248;rgen Holmefjord<p>What pins are you using for TWI and PDM? Could you upload some code showing the setup of both TWI and PDM?

On the PCM two microphones are directly connected to the PDM pins, the TWI bus also contains several devices.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/100106?ContentTypeID=1Mon, 25 Sep 2017 09:28:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a3f8da7f-156d-4a33-a08c-9d9b4f05f1f7J&#248;rgen Holmefjord<p>Are you using the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.0.0/hardware_driver_pdm.html?cp=4_0_0_2_6">PDM driver</a> and <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.0.0/hardware_driver_twi.html?cp=4_0_0_2_16">TWI master driver</a>?
