Hi, I am playing with the SDK13 examples, UART (w/o softdevice). I use gnu gcc. The example runs and when I type q or Q the code goes to the printf(" \r\nExit!\r\n") as designed...
Hi
I read somewhere that when using internel ref for analog measurements the Vin changing does not influences the analog reading. Is that true?
Please, consider the circuit...
Hello,
I am looking through the data sheet for the NRF52 and do not see anything for writing to NVMC.
I see you can erase and configure the NVMC using:
