Hi,
I'd just start developping with the nRF52832 and I would like to communicate with a sensor using the I2C protocol. Has I am a stranger with the nordic uC, I would like...
Hi guys, me again.
I was very confused with my current process on developing with nrf chip now... so I would like to post my develop step and some problems I had so maybe...
I am using ATT MTU throughput example and I noticed that using CLI (calling cli_start) causes the main while(1) loop forever. In other words, wait_for_event does not block...
I just received the Nordic nRF52-DK, and am unable to do anything with it as my laptop does not recognize when it is connected. I do not have the original cable as I did not...

Hey guys,
how can we use DSP math functions on the nRF52832 little monster?
Is there somewhere some documentation?
What about power consumption and performance?
