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 run a laptop which previously ran this fine on Windows 7 x64. I now run Windows 10 x64.
I cleaned out j-link, nrfgo studio, libusb etc and reinstalled nRFgo Studio again...
I know that it is possible to make 4 PWM outputs, but I need to generate 5. I will be using SoftDevice 110 and BLE. Is there any possible way to generate a 5th PWM output...
Hi,
I need to interface a LED driver (PCA9632) using TWI.
In the TWI APIs I can't see any way to pass the slave address to the TWI instance. Speaking about the nrf_drv_twi_init...
Hi Guys,
Thanks for your precious time and insight. Let me try to explain what we did,
We have developed a custom board
After assembling the board, we do a bare board...
Hi, I have an nRF8001 on a Red Bear Lab BLE shield mounted on an Arduino Uno. I'm using BLE to trigger the execution of potentially long running (well, a few seconds anyway...
Hi,
I've done a fair amount with the NRF51822 and Keil on Windows but decided it was time to switch to my native Mac instead of the VM!
Reading all the guides around...
Hello everyone,
I'm a beginner and i'm trying to debug a nRF51422 BLE project.
