Re: Using shell with RTT console on nRF52840 DK

Michael Rosen



Unfortunately, as RTT is just buffers in memory, there is no good way I can think of except to have a low priority background thread which polls the input channel using GetKey() and yields if negative (basically what WaitKey() does but with a yield). It might be a good idea to create an issue on github to track this request if you haven’t already.

Hi Rodrgo,


Krzysztof (on copy) is working on RTT and logging as well.


There’s this PR from him under review at the moment:

I was taking a look at the uart_console and I couldn't any straight solution for RTT.

Uart has a device driver that enables us to use an ISR approach which is cool. There is no device driver for the SEGGER (at least, I could not find it), so the only thing I have in mind right now is to make a polling on the SEGGER_RTT_HasData function to see if there is data to be read from the host, if so write it to the input hook. For me, it seems to be a not so good solution. What do you think? Any other idea?
