Can not configure NFC pins as GPIO to TOGGLE pin with TIMER1 using the freeRTOS demohttps://devzone.nordicsemi.com/f/nordic-q-a/53321/can-not-configure-nfc-pins-as-gpio-to-toggle-pin-with-timer1-using-the-freertos-demoHi, I&#39;m working on a project that is using the the freeRTOS and I want to use the NFC pins P0.9 P0.10 to drive SOFTWARE SERIAL UART with a timer like TIMER1, when I try to toggle the signal the pin does no change at all to HIGH or LOW but if I runen-USTelligent Community 13Tue, 22 Oct 2019 07:37:51 GMTRE: Can not configure NFC pins as GPIO to TOGGLE pin with TIMER1 using the freeRTOS demohttps://devzone.nordicsemi.com/thread/216065?ContentTypeID=1Tue, 22 Oct 2019 07:37:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b2ce2a86-2f7f-4c36-87c4-300c246efb83Susheel Nuguru<p>Hi Francisco,</p> [quote user=""]when I try to toggle the signal the pin does no change at all to HIGH or LOW but if I run the same timer without the freeRTOS demo the pin can toggle just fine[/quote] <p>This seems to me that there are some priority issues with the contexts you are running.
