Btn.addButton() with interrupt

[KGBEl]

Hi out there.

I have copied the example from https://z-uno.z-wave.me/Reference/ZUNO_ ... addButton/
and it works well.
In the text there is a hint of BtnButtonModeExtInt wich you can use instead of BtnButtonModeTimer
in the example.

My question is, how do I set up an ISR and let the interrupt find its way to that ISR.

I found out that attachInterrupt() is not working in this case.

Very thankful in advance.

Hello.
Replace

Code: Select all

init.mode = BtnButtonModeTimer;

on

Code: Select all

init.mode = BtnButtonModeExtInt;

Thank you for answering, I did that but I haven't found out how to catch the button press.

How do I set up an isr so I can catch the interrupt?

If you check button presses, then as in the example:

Code: Select all

void process_buttons() {
	if(Btn.isSingleClick(BUTTON)) {
		Serial0.println("isSingleClick");
		if (dimmerValue == 5)
			dimmerValue = 100;
		else
			dimmerValue = 5;
	}
	if(Btn.isTripleClick(BUTTON)) {
		Serial0.println("isTripleClick");
		if (dimmerValue == 5)
			dimmerValue = 100;
		else
			dimmerValue = 5;
	}
	if(Btn.isLongClick(BUTTON)) {
		Serial0.println("isLongClick");
		if (dimmerValue == 5)
			dimmerValue = 100;
		else
			dimmerValue = 5;
	}
	if(Btn.isDoubleClick(BUTTON)) {
		Serial0.println("isDoubleClick");
		if (dimmerValue == 5)
			dimmerValue = 100;
		else
			dimmerValue = 5;
	}
}

If you need an interrupt callback, this class does not currently provide this.
You need to use attachInterrupt https://z-uno.z-wave.me/Reference/Inter ... Interrupt/ instead of this class.

Thank you for answering.

If I understand you right, there is no way to use BtnButtonModeExtInt and get an
answer to pushed button without polling the Btn.xxxx for events.

Best is to use attachInterrupt() an work around?

One more question, is there a plan for getting an callback on BtnButtonModeExtInt?

Yes that's right.

At the moment there are no plans for this.
