I2C communication with nrf5340 custom board

[Vivek]

We are using nrf5340-dk to communicate with nrf5340 custom board and trying to search for the other sensors' addresses. There is secure mode and unsecure mode CPU. Which mode to try on? We could not detect the sensors I2C addresses.

Hello Vivek,

the Blinky sample acutally is quite a good one to demonstrate the usage of the LEDs.

If you want to modify the LED properties, you can do it in the overlay file as shown below for LED0:

&led0 {
	gpios = < &gpio0 0x1c 0x1 >;
	label = "Green LED 0";
};

I hope this will help you!

Regards,

Markus

Hi Markus,

from this:

&led0 {
gpios = < &gpio0 0x1c 0x1 >;
label = "Green LED 0";
};

from gpios  &gpio0  is gpio name,  0x1C is pin number  and 0x1 is pin status high/low

 

1 for high and 0 for low.

Is my understanding correct?
