Hello, Mr, NCK!

Could you have a look at hmolesworth answer in this case for a suggestion on how you can interface with the device? For suggestions on how to use GPIO with Zephyr I suggest that you check out one of the basic samples.

Best regards,

Hi Carl,

 Thank you, for your response. I need to configure the GPIO as input and I  need to read the digital signal via GPIO

. In the given samples GPIo as config as Output but I didn't see any Input Configuration. For this, Kindly tell me the procedure

Thanks & Regards

Hello again!

In order to configure GPIO as input you should only have to do something like this:

ret = gpio_pin_configure(gpio, pin, GPIO_INPUT | flags);
if (ret < 0) {
	LOG_ERR("Failed to configure pin %u, error: %d",
		pin, ret);
	return ret;
}

Other available flags and other relevant information can be found in the GPIO API reference.
