Problem with UART Communication

[nikola]

Hi,
I am trying to test the uart exemple on nrf52840 using external debugging as shown in figure but it doesn't function !!!!

are there any modifications that need to be added compared to the internal debugging mode or is it the same thing?

Hi,

What board are you're flashing the UART example on? 

 

are there any modifications that need to be added compared to the internal debugging mode or is it the same thing?

 Yes, you need to change the board map file so that the pins on fits the board that you're using.

I am flashing the example on the board nrf52832 and I put the connection of pins as following

Rx==> P08 (Pins of nrf52840)

Tx==>P06

CTS==>P07

RTS==>P05

then I put modification on the file pca10040.h to get the correspendant pin of nrf52840 but it doesn't function .

Strange, I tried downloading the file and was able to open it just fine. Are you sure that you're opening the correct file? You should open the SEGGER Embedded Studio Project File:

yes I just open this file

Hi,

Are you using SDK v17.02? The example has been made with that SDK version

[nikola]

yes I am using this version of SDK

Hi,

I've tried downloading and opening the project and didn't see any issues. 

Could you try copying the contents of the files into the UART example. You also need to include the files to the build as previously mentioned. Does it build successfully now?

I am trying with this example and it dosen't function :

Hi,

It seems like the project is looking for the log folder in the wrong place. Right now it's looking for a component folder that lies in the Desktop folder? Is this correct according to your setup? Normally it would have looked after a component folder inside the SDK.
