Issue with Configuring MAX30101 with nRF Connect SDK

Hi Jack,
I would suggest to use prj.conf directly. It's the easiest way.
Otherwise if you want to use GUI, you can use the nRF Kconfig GUI

Then you can click save minimal and save it as a .conf overlay file. Make sure to use this overlay file in your project.

Yes, I do see the .config change by changing the prj.conf file in my project.

Is there any way that I can use the GUI to configure it?

Hi Jack,

Could you confirm that you now can build and don't have to change .config manually ?

Sometimes VSCode couldn't get all the configurations correctly and will show some warning. But if you can build with no problem then it's fine. You may want to try remove the build configuration and build again with VSCode.

Hi, Hung,

Thanks for the reply. Here is the device tree overlay.

// To get started, press Ctrl+Space to bring up the completion menu and view the available nodes.

// You can also use the buttons in the sidebar to perform actions on nodes.
// Actions currently available include:

// * Enabling / disabling the node
// * Adding the bus to a bus
// * Removing the node
// * Connecting ADC channels

// For more help, browse the DeviceTree documentation at https://docs.zephyrproject.org/latest/guides/dts/index.html
// You can also visit the nRF DeviceTree extension documentation at https://docs.nordicsemi.com/bundle/nrf-connect-vscode/page/guides/ncs_configure_app.html#devicetree-support-in-the-extension
&i2c0 {  
    max30101: max30101@57{
        status = "okay";
        compatible = "maxim,max30101";
        reg = < 0x57 >;
    };
};

&gpio0 {
	status = "okay";
};

When I attempt to set any MAX30101-related configuration, I receive a warning message. Interestingly, despite the warning, I still see the configuration changes from prj.conf reflected in the .config file.

Hi Jack,
Could you show your device tree board configuration ?

If you set a node with compatible = "maxim,max30101" then DT_HAS_MAXIM_MAX30101_ENABLED will be set.

Have you tried to set CONFIG_MAX30101_LED2_PA=0x33 in your prj.conf ?
Editing the .config file directly is not the best way to do configuration.
