adding lvgl to thing53 breaks building

[ctyerman]

im trying to develop a prototype that uses a thingy53 and lvgl to draw a screen on a solomon ssd1306 attached via i2c (kwiic) but am having issues with getting it to build

im using v2.91 SDK and toolchain  installed via nRF Connect Extension


after various failed attempts

i created a blank new application

with a board target thingy53/nrf5340/cpuapp which builds with only warnings


if i add proj.conf with  CONFIG_LVGL=y  the build breaks

Hi

From the logs we need to look at your overlay to be able to debug further. Can you upload it here? 

As you have written you started with a blank application, have you created an overlay? in general I would suggest to not start with a blank application, but rather a sample that is close to what you want to achieve and build on it. 

Regards

Runar

i think i get the problem now the is looking for specific Device tree node values based of chosen node, and the chosen node requirement was not obvious.

I was trying to get something to build successfully by eliminating extraneous code.


I now have tried using the lvgl sample (samples/subsys/display/lvgl)

and the following overlay(based on the ssd1306 shield (boards/shields/ssd1306) which says is compatible)

&i2c1 {
	ssd1306_64_48: ssd1306fb@3d {
		compatible = "solomon,ssd1306fb";
		reg = <0x3d>;
        segment-offset = < 31 >;
        page-offset = < 0 >;
        display-offset = < 0 >;
        multiplex-ratio = < 0 >;
        prechargep = < 0x22 >;
        height = < 64 >;
        width = < 48 >;
        inversion-on;
        
	};
};


/ {
    chosen {
        zephyr,display = &ssd1306_64_48;
    };
};

which builds successfully but has the same error if chosen node removed


the requirement for a default display being defined in the device tree to build the lvgl module is interesting

thanks for the assistance

[runsiv]

Good that you have it working. Displays are one of those where you need to use chosen property, you can read more about it here
