Hello everyone,
I am trying to implement a bootloader to my application to be able to enter in DFU mode.
I am using nrf51822 (32KB ram 256 flash) and s130.
I have taken...
My understanding is that the nRF51 is known to need a fairly stiff external pull-down resistor on SWCLK to avoid noise putting the chip into debug mode. I note that the nRF52...
I'd like to know how to implement a bootloader for the Nordic SoC nRF51822-QFAA-R in order to boot the softdevice and some firwmare. If will be great getting an application...
Does nRF52832 have battery monitor?
I can't find in the datasheet if there is an externarl circuit to monitor the battery. I'm using a CR2032 coin cell battery.

Hi,
I'm developing some firmware that will hopefully run on a few different kinds of nRF52 device.
Is there a way of detecting if the DC-DC converter's inductor/capacitor...
