RE: [NRF54L15DK] How to use the LVGL to control ssd1306 OLED?

Hello,

I have seen that you have commented out the SSD1306 device node from your overlay file, that is because you have used arduino shield. You have to add the shield in the device tree overlay file under the i2c1 node like following way (pointing this arduino_i2c: &i2c21 {};)

&i2c21 {
    compatible = "nordic,nrf-twim";
    status = "okay";
    clock-frequency = <I2C_BITRATE_STANDARD>;
    zephyr,concat-buf-size = <4096>;
    pinctrl-0 = <&i2c21_default>;
    pinctrl-1 = <&i2c21_sleep>;
    pinctrl-names = "default", "sleep";
};

arduino_i2c: &i2c21 {};

&pinctrl {
    i2c21_default: i2c21_default {
        group1 {
            psels = <NRF_PSEL(TWIM_SDA, 1, 11)>,
                    <NRF_PSEL(TWIM_SCL, 1, 12)>;
            bias-pull-up;
        };
    };

    i2c21_sleep: i2c21_sleep {
        group1 {
            psels = <NRF_PSEL(TWIM_SDA, 1, 11)>,
                    <NRF_PSEL(TWIM_SCL, 1, 12)>;
            low-power-enable;
        };
    };
};

In the prj.conf file, you should not coment out

CONFIG_SSD1306=y and CONFIG_I2C=y.
