Hi
My view is it is Interrupt on Change, any change, therefore it is up to you how you handle the response.
Does the datasheet specifically state that you can mask IOC to suit your specific needs? I'm not an expert on that chip but I do remember Int0/1 can be masked.
Hope this helps.
Regards

Re: arduino INTERRUPTS - IOC PORTD... do not select..
Hi I'm not an expert on UNO. Int0 and Int1 can be selected to trigger on various "edges" as documented in the interrupt properties. IOC on the remaining ports do set a flag (green) which indicates a trigger on both edges (Interrupt On Change). If you set pins, close and reopen the window you will se...

Re: Matrix Keypad Issues Disturbance
Hi
I'd confirm your connections to start with.
Regards
That sounds like the inputs are floating (unconnected, no weak pull-up / down) and when your hand goes near, the capacitive effect is causing the inputs to change.when I put my hand near my Arduino it starts reading random inputs
I'd confirm your connections to start with.

Hi
Impressive stuff indeed.
I hope that's a screenshot from your Sinclair

Re: Worked examples HTTP via serial port
Hi
You need to be a bit more specific in your requirement.
Android, Linux and Windows already have serial programs that can do such.
What is it you actually want it to do?

Re: SR04 Ultrasonic Sensor
Hi Lab is in a bit of a state just now, in the process of a good clean out, getting rid of the "might come in handy" pile amongst a LOT of acquired useless junk. That's my "Ivory Tower" up in the clouds, i.e. the mezzanine floor I built to elevate my status :) Scopes / analysers / soldering / test e...

Re: DSP made easy
Hi Whenever I could squeeze in the time I've been working my way through the tutorials and decided I needed a "white noise" generator so that I can experiment with filters a bit better. Six weeks later I'm in possession of a Chinese generator. Now I knew it was a kit but must admit to being surprise...
