Thingy:91 I2C access - Where do I find the information required to create a 'NEW' I2C device?

Where do I find the information required to create a 'NEW' I2C device and assign it to nRF5280 P0.26/27/28 as SCL/SDA/INT Thanks

Hi Kevin,

There is some limitations to what is available in terms of IO on the Thingy 91, P6 connector interfaces with the nrf52 on the Thingy91 product. Is the plan to use an external sensors or interface?

Using NCS you can add something like this in the .dts or .overlay file

&i2c {
	compatible = "nordic,nrf-twim";
	status = "okay";
	sda-pin = <26>;
	scl-pin = <27>;
};

And here is a list of what can be used at the same time:Nordic Semiconductor Infocenter

Here is a different Devzone case that might be of interest: Nordic DevZone (nordicsemi.com)
