🔥Another class for the Arduino 101 series. These videos will have some more difficult Arduino programming. In this video I show you how use the pin change interruptions and make the code a lot faster.

@FredDeckerNC 2 года назад

Another thank you for a great video. Including the cool graphics where the pin diagram floats with the chip you are holding! One thing though, in English, at least in the United States, they are called an "interrupt" or "interrupts" not "interruption" or "interruptions". I suppose you could say that an interrupt can cause an interruption to the flow of your code, but an interruption would be an action, where an interrupt describes a "thing" or noun, just like a pin or a timer. We wouldn't call a pin a "pinning". :)

@andremuensti4730 3 года назад

Very good ! But all variables should be declared with “volatile” that are changed in an ISR. For example (at 9:47 ) code: volatile bool D4_state = LOW

@retrohd1_ 2 года назад

9:49 Found an error! It was confusing me for quite a while why you had set "D4_state" variable to LOW at first and then to HIGH in the very next line. It's actually "D5_state" in line 11.

@MonidethPen 3 года назад

Thank you! A fantastic tutorial with excellent visual examples. I have a question - does the PCINT interruption only occurs when you are in the main void loop() function? Or can it occur in a while loop in the void setup() function too?

Awesome, this will help me in my menu selection function of my reflow oven project. Are you going to explore software interrupts like timer1? I want to update the temperature on my display graph every 2-seconds, no matter what function it is performing. I think using millis to trigger the interrupt is the best approach.

@1yyymmmddd 2 года назад

Great tutorial! Thank you. Is it really bad idea to make some processing in the ISR? Many times you'd like to ignore other interrupts before current interrupt is processed.

@nilsbruhner1983 3 года назад

Thx for excellent tuts. If wanting to return the clock cykle value instead of the micros() for better accuracy. Say one want to use the PCI for triggering two mics to get the angle of arrival, whats the maximum resoultion on an UNO? Lots of my students namely want to do "robots" that can get the angle of arrival of sound to stear them... :) im stuck there..

@rickmorris3580 2 года назад

Hi, I don't know if you reply to comments on old videos but here goes. Could you use interrupts to run both InfraRed Transmit -> InfraRed Receiver on a single Arduino nano (IRremote.hpp)? Normally you would be stuck in IrSender until you have sent a complete code (e.g. IrSender.sendNEC(sAddress, sCommand, sRepeats);) and if you are receiving you would be stuck in IrReceiver until you receive the IR code. You couldn't transmit and receive at the same time. I was easily able to do this with two arduino's (one Tx and one Rx) but could it be done with one? So just to be clear...I'm trying to transmit an IR code and simultaneously receive the same code. Maybe what I'm asking for is true multi-tasking which much more than an ISR.

@himanshujangra2599 3 года назад

Actually i have a question if 2 pins of port d are used for pcint then is we can use other pins of port d as output pins?

@ELECTRONOOBS 3 года назад

Yes you can. You can define PCINT for some pins and use the rest of the port as OUTPUT and set them LOW/HIGH.

@nicobugs 3 года назад

2:34 these are not instructions but statements. A statement can result in multiple instructions in the compiled output.

@poptartmcjelly7054 3 года назад

Normally interrupts have priority levels and lower priority interrupts are left pending until the higher priority interrupts are completed. Also higher priority interrupts can interrupt lower priority interrupts. Is this also true on the Atmega or are all other interrupts really blocked when an interrupt is called?

@ELECTRONOOBS 3 года назад

With PCINT on the ARduino UNO only has one level of interrupt. Also, as I say in the video, interrupts are turned off during an ISR. If the ISR for interrupt 0 is executing and interrupt 1 occurs, it will be held until interrupts are turned on again after I0 has finished.

The numbers stay on the screen, then the device is reset with whatchdog. This is starting to get annoying. can you help me with this

@incxxxx 3 года назад

You said that PCINT works not only for RISING OR FALLING but also for LOW or HIGH. I was looking for such case with LOW or HIGH, but I did not found. Are you sure you are correct?

@ELECTRONOOBS 3 года назад

Hi. No, what I've said is that PCINT only works with low or high. It could not detect edges. So you have to detect the edges by storing the previous state and compare with the new stare and by that you know if it went from low to high or from high to low.
