Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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 been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

Hi,
We are using Jlink and nrfjprog to program the nRF52832 flash via SWD interface. We have a combined hex file which is about 512k and takes about 12 seconds to flash...
I am debugging my applications transitions to SYSTEM_OFF and back again. I am connected to the debugger so I am presumably testing with "emulated system off" which is just...
Hi all,
I wrote a nice library for using an offboard SPI flash chip and am now trying to port it to our master code which runs on freertos.. I wrote the library starting...

Hi all,
In my current project I have 7 sensors, each hooked up to an own nrf52. I am polling between 8 and 28 byte(depending on operation mode) of data in 10ms intervals...
I created a copy of bluetooth/peripheral example and copied the nRF5340DK board files to make my custom board definitions. The guideby Øyvind A. Sandberg is really good here...
Hello All,
I'm interfacing a temperature sensor ds18b20 with nFR52840, which uses one wire protocol.
I'm using this repo https://github.com/DSysoletin/nrf52_ds18b20_example...
Hello! I wrote my own version of the bootloader for nFR52832. If I go into the loader, check the application and switch to its execution via nrf_bootloader_app_start (), then...
