current sensing

[Rihab]

Hello everyone,
i'm trying to deal with the ACS714T sensor 
but i can't find any samples or guide through internet 
the communication need to be done through ADC and SAADC HAL
but i don't know from where to begin with this 
i tried the ADC sample on the Zephyr documentation to have a closer look but it didn't help me a lot
is there a guide on how to do with the sensors that are not premade by Nordic 
what do i need to do first to deal with this sensor ?  
i'm a bit lost with it 
can you give me some guidance please 
i would appreciate your help

Hello,
i found this tutorial ADC conf
i tried to make something similar but i don't succeed to run it 
i'm putting it below 
please correct me

Hello everyone,
i created a new version of project based on ADC sample 
on the NRF5340dk 
but i think i'm missing something related to the overlay file 
this is my projectp_adc.zip
i'm keeping getting the error of the device tree it says #error "No suitable devicetree overlay specified"

can you help me with this please

Hello,

The tutorial you linked used NCS v1.4.0, but the board names has since changed, so you will need to rename the overlay file from nrf5340dk_nrf5340_cpuappns to nrf5340dk_nrf5340_cpuapp_ns for this to work with newer versions of the NCS SDK.
Please try this, and let me know if the issue persists.

Best regards,
Karl

Hello,
i did changed the overlay file name but it doesn't work anymore
it's not even opening 

[Rihab]

what can i do please to figure out this issue, i can no longer open my project 
can you help me please 

[Karl Ylvisaker]

Hello again,

I just looked over your overlay file. Please change your adc section to instead be:

&adc{  

        compatible = "nordic,nrf_saadc,nrf_adc";

        status = "okay";

};

I.e remove the compatible line and add a semicolon at the end.

Best regards,
Karl

Hello again,
i even created a new project with the same items within and with the config you recommended in previous comments but unfortunately always the same error 
" create_nordic_project.py failed(1) and i can't open the project 

[Rihab]

here's the output after the error " create_nordic_project.py failed(1)"

[Karl Ylvisaker]

Oh, my mistake, after closer inspection it seems the tutorial you are following does things a little bit differently - could you change your overlay file to contain just the following:

/ {

    zephyr,user {

        /* adjust channel number according to pinmux in board.dts */

        io-channels = <&adc 1>;

    };

};

Let me know if it compiles with this change, or what the error log says if it does not.

Best regards,
Karl
