Hi,
UART and UARTE are specified in data sheet. these are separate UART or one UART and configured bt software. Please explain.
Thanks and Regards,

So literally, I cannot trust what IAR is doing. Running version 8.22.1, it crashes every time I attempt to debug an nRF52832 device (SparkFun board).
I've already programmed...
i'm using uart for debugging, works fine and dandy except when in app_error_handler.
There only the first character is being printed before we go into an infinite loop. Inside...
Hello,
My custom board is based on an accelerometer which sends interrupts to nrf52832 to Sleep and Wake-up (pins GPIOTE).
