RE: Turning on TWIM/TWIS without devicetree

Hello,

You need to enable the i2c0 node in your device tree to inform the build system that the hardware is present on your device. However, you should change the 'compatible' field to use the binding for the TWI slave:

&i2c0 {
    status = "okay";
    compatible = "nordic,nrf-twis";
};

After applying the DT overlay, you can enable TWIS instance 0 in your prj.conf file:

CONFIG_NRFX_TWIS0=y

Best regards,

Vidar
