Capture GPIO change

[1096184876]

I monitor the change of GPIO1. If it from low level to high level, I will set GPIO0 high
I do it

for ; ; {

	if gpio.Watch(0) {
		gpio.High(1)
	}
     }

But build error.Could you provide sample code? thanks

func Watch(pin int) (high bool, err error)

Watch returns whether output voltage is high(true) or low(false) on pin within range 0-3, it’ll be blocked until the voltage of specified pin changed after being called.

You can’t use if gpio.Watch(0) because Watch returns two values.
