i2c node in the dts file

Embedded-world — Wed, 28 Feb 2024 06:03:15 GMT

Dear Experts,

I'm working imx6ull dts files so here,

&i2c1 {
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c1>;
status = "okay";

pcf8563@51 {
status = "okay";
compatible = "nxp,pcf8563";
reg = <0x51>;
};
};

In the above dts i2c structure i didn't understand the @51 and reg = <0x51> values, How to assign these value from the datasheet ? someone could give me clarity about this.

Thanks and Regards,

Ravikumar

Hi @Embedded-world

The 0x51 is your i2c slave device address. You should check datasheet or user guide.

Best Regards
