Hello,
I know that the NRF_TEMP peripheral is a restricted peripheral and should be accessed with the sd_temp_get function when the soft device is running. Heck I even...
Does the NFC library globally disable interrupts at any point? We're trying to track down an issue where our code occasionally misses an I2C event during NFC read/write.
Hi all,
when I try to send 6 bytes of 0xFF, the last bytes change. I use SPI in mode 3. I use the NRF52832 on a custom board using SDK13 with sd v4. See the following screengrab...
