Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi,
I have just bought an nRFGo Motherboard (nRF6310) to develop for the nRF24LE1 (nRF2722). I was able to run some example code on the chip like toggling a pin. Next I...
Hello,
I have an application based on SDK 11 and Softdevice v2.0.0. Also there is a legacy bootloader from SDK 11 for performing DFU.
I am wondering whether it is possible...
