MBLPinChangeTypeRising and MBLPinChangeTypeFalling

kalle

Hi i have a problem,hope you can help

i'm trying to make a project like the metaKeg, but having problems to convert from objc to swift. and i like to make it in swift.

my problem if to get the flow meter to count the puls.

this i what i got in objc c, and it work.

- (IBAction)gpioStartPinChangePressed:(id)sender {   

    MBLGPIOPin *pin = _device.gpio.pins[1];

    if (pin == 0) {pin.changeType = MBLPinChangeTypeRising;}

else if (pin == 1) {pin.changeType = MBLPinChangeTypeFalling;}

else {pin.changeType = MBLPinChangeTypeAny;}

    [self.streamingEvents addObject:pin.changeEvent];

    [pin.changeEvent startNotificationsWithHandlerAsync:^(MBLNumericData * _Nullable obj, NSError * _Nullable error) {

        if (obj) {self.ozPouredLabel.text = [NSString stringWithFormat:@%.1f, (float)(++self.gpioPinChangeCount) * ML_PER_FLOWMETER_TICK * OZ_PER_ML];

}

}

}];

}

Can you attach your swift code as well? Something might of went askew in the translation.

her it's  

func gpioStartPinChangePressed(sender: AnyObject) {
var pin: MBLGPIOPin = self.device.gpio!.pins[1] as! MBLGPIOPin if pin == 0 {
pin.changeType = MBLPinChangeTypeRising
}
else if pin == 1 {
pin.changeType = MBLPinChangeTypeFalling
}
else {
pin.changeType = MBLPinChangeTypeAny
}

self.streamingEvents.append(pin.changeEvent)
pin.changeEvent
{(obj: MBLNumericData, error: NSError) -> Void in
if obj != nil {
self.ozPouredLabel.text = String(format: "%.1f", Float(++self.gpioPinChangeCount) * ML_PER_FLOWMETER_TICK * OZ_PER_ML)
}
}
}
}
}

and it's the MBLPinChangeTypeFalling and the other

Check out this function, it might provide some clues:   

    func gpioStartPinChangePressed(sender: AnyObject) {

        let pin = self.device.gpio!.pins[1] as! MBLGPIOPin

        

        // Here pin is an object, it isn't valid to compare it to an int

        // For kegbot, Any is the type you want

        pin.changeType = .Any

        //if pin == 0 {

        //    pin.changeType = MBLPinChangeTypeRising

        //}

        //else if pin == 1 {

        //    pin.changeType = MBLPinChangeTypeFalling

        //}

        //else {

        //    pin.changeType = MBLPinChangeTypeAny

        //}

        

        self.streamingEvents.append(pin.changeEvent)

        pin.changeEvent.startNotificationsWithHandlerAsync { obj, error in

            if obj != nil {

                self.gpioPinChangeCount += 1

                self.ozPouredLabel.text = String(format: "%.1f", self.gpioPinChangeCount * ML_PER_FLOWMETER_TICK * OZ_PER_ML)

            }

        }

    }
