Measuring Resistance (NHS3152)

HafizUsman — Fri, 07 Mar 2025 11:32:30 GMT

Hi everyone,

I am a new learner and user to NXP community. I am tying to flash a new code to the IC through MCUXpresso IDE to measure the resistance across the resisitor (connnected across ANa-01 to Ana-04) on NHS 3152 demo board. I open the tadherence project file in MCUXpresso and replace the code in (maintadherence.c) with my new code and go for build and debug. There is error not to proceed.

Please anyone guide how we can flash a new code to the IC on NHS3152 demo board?

Is this an assignment to replace the main code with our newone? or we have to change or modify other code files or some settings?

Thanks in advance.

Regards, HAFIZ

Hello, Good Day!

Thank you very much for your interest in our products.

Could you please provide more details on what is the error that you are getting?

A guide for flashing the NHS31XX chip with provided demo applications is available at Getting Started with the NHS3152THADADK | NXP Semiconductors.

For developing your own application on the MCUXpresso IDE and flashing it, please make sure you are following the steps described in the UM11153 document available in the ''SDK Folder/docs/UM11153''.

I would recommend having a look at the ''\sw\nss\example_snippets'' folder in which you can find code examples on various peripherals for analog measurements. You may also find useful information on resistance measurement with the NHS3152 referring to this community thread: Solved: Re: Measure resistance: (NHS3152) - NXP Community.

My best regards,
Daniel.

Hi Daniele,

Thank you very much for your response.

I am interested to measure a resistance (connected across AN01 to AN04 in NHS3152 board) as shown in attached picture-1. I already have followed the steps (mentioned in UM11153) to develop a new project (Named "NEW") as shown in attached picture-2.

I also already have the resistance measuring code following https://community.nxp.com/t5/NFC/Measure-resistance-NHS3152/m-p/831045.

This newly made project "NEW" has its own built-in code file (main.c) which easily go for build and debug options as shown in picture-2.

At this stage, when I replace this main.c code with the resistance measuring code or any other code and go for build options, it does not work as shown in picture-3. There are many errors displayed.

My question: How to write or convey any new code to this newly made project that can go for build and debug option. Please guide regarding current scenario. Thank you

Regards,

Hello @HafizUsman, Good Day!

It appears that some errors related to language syntaxis exist in the code you are trying to build; to address them you may take a look at the terminal to find out the reason of each error and try and handle them individually.

Please consider that the SDK for the NHS3152 is based on a determined architecture which is described in the ''SoftwareOverview'' document available in ''SDK folder/docs'', so it has a specific flow that has to be maintained when working with the library. I would recommend using the examples provided as a starting point, modifying the code little by little to get a hold of what each line does within the execution, and only add the specific functional parts you need to meet your requirements.

This approach should prevent getting errors caused by interfering with the flow of the library.

My best regards,
Daniel.
