We're quite interested in producing an nRF52 design based on the solar beacon (great design, and clean software). I appreciate the relative simplicity and manageable BOM cost...
Hello,
I am developing a system that samples 3 independent data using SSADC. since the timing was important in my system, I decided to use PPI to trigger the SSADC.
However...
When using app_timer through scheduler, a break and go will overflow the event queue if a timer is a repeat timer. The effect is that it's not possible to debug.
To work...
Hello all
I am trying to implement hardware flow control for UART.

Hello,
I was wondering why I am not getting a theoretical sampling rate as I set them to with a timer.
I am using PPI to trigger a SAADC sampling with the timer to set...
Hello!
Nordic UART Service (NUS) is a pretty handy way of implementing a serial data transfer service over BLE. The nRF Toolbox on Android makes it very easy to test it...
Hi,
While this is not related to Nordic Semiconductor products, I think we should incorporate Captcha system during user registration. We had some spam in the morning and...
I need to be able to actively set the value being incremented in the Timer2 register on the nrf52 (what I believe would be it's main register). It seems that this might be...
Hi,
is there any example how to reset the hole device? Are there any example codes for using something like system_off or system_on ?
Best regards Nils
