Hello,
I'm using an NHS3152 evaluation board (with LPC-Link2 board).
I'm trying to use the NFC communication. I used parts of codes I found on the community forums.
I have it seems a set up problem as there is no link to the ndeft2t/ndeft2.h. When I build or debug my short project, I have this error :

Here is an imùage of my MCUXpresso
I fail to see why it does not find that file
thanks for your help
Dear Daniel,
ok I have the paths listed in your picture (see image below)
One of the already included the ndeft2t files ("${workspace_loc:/modes})
nevertheless, I explicitly gave the the full path the files.
I also included the files in the Inlude File section.
The error is not the same, in this sense it corrected the initila error).
Here ar ethe errors I now have
Any suggestion?
regards
Cyril
Hello Daniel,
I'm not yet familiar with the tool MCUXpresso.
I'm certainly missing a link, a path to the ndeft2t.h file. But looking at my project explorer you can see that I have the ndeft2t folder listed in "mods".
Maybe I need it elswhere. but don't see where / how to add it. If you can enlight me...
best regards
Cyril
ok,
I added that line:
to provide a path where the ndeft2t.h file was.
it seems to have done the work, I don't have the error anymore.
Thanks
Cyril
