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 All,
I am using nRF52840 in one of our design. As the P0.18 is the RESET pin, it is tough to route the trace without a pad on via. Hence as I have modified my design...
Hi Friend,
My platform is SDK 16 with S140 softdevice.
I set a gpio for edge trigger interrupt. But I cannot get the correct gpio state if the data pulse is too short...
Hello,
I want to test bluetooth on nRF9160DK. How to do that? I programmed nRF52 on nRF9160DK with hci uart sample and board selected is nrf52840_pca10090.
But how to...
