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...

It is possible to load a new firmware in a NRF51822 PCBA using the Nordic Development Kit NRF51DK?
Do I need a special connector?
This is the beacon Module I pretend...
Hello,
I have a board with an RFDuino on it which uses a Nordic nRF51822 internally. We are seeing a few of them auto-brick when the input voltage dips too low.
My first...
I have a question about the usage of Flash Data Storage, chunks and parsing of the data retrieved from FDS.
How, when and why are you supposed to use "chunks" when setting...
Hello,
I would like to implement an interface with an external SPI ADC using the nRF52832.
