using multiple SPI slaves sensors

[yogeshiggalore]

Hi all, 

I am working on interfacing 2 SPI sensors ADXL362 and ADXL372 for learning purposes. Following is the overlay created for the same.

&spi1 {
	compatible = "nordic,nrf-spim";
	label = "SPI_1";
	status = "okay";
	sck-pin = <41>;
	mosi-pin = <40>;
	miso-pin = <4>;
	
	cs-gpios = 	< &gpio0  26 GPIO_ACTIVE_LOW>,
				< &gpio0  27 GPIO_ACTIVE_LOW>;
				
	adxl362@0 {
		compatible = "adi,adxl362";
		label = "ADXL362";
		spi-max-frequency = <1000000>;
		reg = <0>;
		int1-gpios = <&gpio0 9 0>;
	};

	adxl372@1 {
		compatible = "adi,adxl372";
		label = "ADXL372";
		spi-max-frequency = <1000000>;
		reg = <1>;
		int1-gpios = <&gpio0 6 0>;
	};
};

if anyone has multiple device examples or samples will be helpful.

Hi,

You might want to look first at DeviceTree introduction.

More information about DeviceTree and overlay files can be found in DeviceTree, setting DeviceTree overlays and using DeviceTree overlays.
Board files are also explained in this tutorial.

We don't have ready made samples with multiple sensors, but you can find single sensor examples under zephyr\samples\sensor\sensor_name\boards\overlay_name.overlay.

Best regards,
Dejan

hi dejans,

Thanks, for the answer. I am able to configure multiple cs control pins. It is working as expected.

Hi,

Thank you for your update.
I am glad that it worked for you.

Best regards,
