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...

Hello,
I am trying to read multiple registers from a slave of i2c.
The values that I capture are the first value repeated in all the buffer.
The number of readed reg...
Hi,
I would like to use ping pong mechanism to prevent faulty application update on nRF52840. Is there a way to build a single image to run at 2 different addresses? How...
I have OSX Sierra, VMWare Fusion and Windows 7 available.
I do Arduino (Teensy) dev, staying on the OSX side.
I want to use the nrf52 chip as a MIDI over BLE conduit ...
Hello,
I have a PCB with a NRF52 powered by batteries. We need to be able to plug the batteries, then program the device and never remove the batteries.
We noticed, that...
I have a need for an interrupt to go off at a 4khz rate. For this, I am using a repeated App Timer (running off the 32k crystal).
Prior to adding this extra timer, we used...
I'd like to run the DK in at the lowest power in SYSTEM_ON mode.
It's my understanding that the ble_app_gzll example places the system in the "low power" SYSTEM_ON mode...
Hello Folks
I would highly apprciate if anyone can point me in the right direction here
After lot of consultation we imported a smal size shipment (of about 1000 nRF51822...
