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...

I was wondering what determines the logic level of the nRF52840 interfaces? Is it whatever you supply VDD with?
For example, if I supply VDD with 2.8V, will the logic...
I need to port a system from a STM32F407 MCU to the nrf52832.
The old system would continuously poll a SPI slave for 244 bytes of information and after receiving 60 valid...

Use Keil to program application firmware
Does not work:
Use nRF Go studio to detect...
I need to implement a simple uart protocol. most messages are fixed length (8bytes) with some exceptions.
here what I do in pseudo code, I send 8bytes and expect 8bytes...
Hi
I am trying to port an SPI driver from a project for the NRF51822 to an NRF52832 and running into a problem reading more than two bytes. We are using SPI0 (not SPIM0...
Hello,
I'm using an NRF52 DK board.
I noticed that when I change P0.27 from the default (input / not connected to input buffer) to being an input pin connected to the...
