Hello again,

[quote user="Rihab"] it compiled [/quote]

Great, I am happy to hear that!

[quote user="Rihab"]i need to get the current and average values from the acs714 sensor
do you know how to proceed to collect those values through ADC please
can help me with that please
do i need to add things to the prj.conf about the sensor ?[/quote]

I have never worked with the acs714 personally, but from your description I assume that you are supposed to measure a voltage, and the process the measured value to get the current?
If so, you could use the same setup as Simon describes in the tutorial you looked at earlier where you make sure that the pin you would like to measure on the acs714 is connected to the NRF_SAADC_INPUT_AIN0 pin on the NRF, or change the pin to match your connection.
How do you need sampling to be triggered in your application? In the tutorial it just samples every 200 ms, but what are the requirements for your application?

Best regards,
Karl

yeah, it compiled
i need to get the current and average values from the acs714 sensor
do you know how to proceed to collect those values through ADC please
can help me with that please
do i need to add things to the prj.conf about the sensor ?
how can i proceed to get them displayed please
i appreciate your help very much

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

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

RE: current sensing

Karl Ylvisaker — Thu, 09 Dec 2021 14:31:40 GMT

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

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

RE: current sensing

Rihab — Thu, 09 Dec 2021 13:59:25 GMT

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

RE: current sensing

Karl Ylvisaker — Thu, 09 Dec 2021 13:42:55 GMT

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 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 projectdevzone.nordicsemi.com/.../p_5F00_adc.zip
i'm keeping getting the error of the device tree it says #error "No suitable devicetree overlay specified"
