Combine two or three "I2C" Devices with NRF5340

[Mr.NCK]

HI,

 I have already got output from each of the SHT20 and MLX90614 sensors. Now I want to combine both the code. Regards, I need an help to Setup prj.conf file

Thanks & Regards

Hi Heidi,

5732.nrf5340dk_nrf5340_cpuapp.overlay

while opening the project with the above overlay file I have facing the error called

create_nordic_project.py failed (1)

the log was

I think the above error is because of the Device tree. Already, You know our requirements. Kindly check my overlay file and correct me.

    Kindly respond, We are waiting for a long time. 

Thanks & Regards

Hi

As I mentioned earlier, due to the summer holidays, long wait times on DevZone are to be expected.

In the log, it says

devicetree error: 'interrupts' is marked as required in 'properties:' in F:/v1.5.0/zephyr/dts/bindings\i2c\nordic,nrf-twim.yaml, but does not appear in <Node /soc/peripheral@50000000/i2c@8000/BNO055@28 in 'nrf5340dk_nrf5340_cpuapp.dts.pre.tmp'>

so you need to add the "interrupts" field in all the I2C sub-nodes, because it's specified as required by the binding file.

KIndly, give me some example

[Heidi]

Hi,

After taking a closer look, I see that you're defining all the sub-nodes with the "nordic, nrf-twim" binding, which is incorrect.

For the compatible-property of the sub-nodes, you need to use the vendor specific bindings, not "nordic,nrf-twim". 

For example, in the BME680 Sample, the BME680 device is defined with the BME680 binding:

&i2c0 {
	bme680@76 {
		compatible = "bosch,bme680";
		reg = <0x76>;
		label = "BME680";
	};
};

Source: zephyr/samples/sensor/b,e680/boards/nrf52840dk_nrf52840.overlay-L9

It doesn't look like any of the devices you are using have a binding definition in Zephyr (see the Bindings index for a complete list of available devicetree bindings in Zephyr).
