This video will demonstrate the use of interrupts and use the timer/counter as an example.
Equipment that I use to make videos:
Canon EOS Rebel: amzn.to/2rJSeh0
Macro Lens: amzn.to/2qaSKmK
Microphone: amzn.to/2qO2RB4
3D Mouse to rotate/zoom/move the object (Must have for CAD!!!): amzn.to/2ruFnSn
The drafting pencil I use on these videos: amzn.to/2qioYg2

These video lectures are absolutely beautiful. I have no idea how I could ever learn about microcontrollers without your videos. For my exam and project I am only relying on your videos. You are indeed a great Teacher!

@therewbb 7 лет назад

Very clean and understandable explanation so far, it is way more easier to understand interrupts and other things when you explain them. Thank you!

@strogg117 13 лет назад

same here. Keep it coming. very good info for students like me.

@Kratasish 9 лет назад

Crazy background sounds as usually :-D I like it ;)

@oguzhansisman3591 4 года назад

i couldn't understand nothing before timer/counters and interrupts by myself but this video is awesome great job from BuildYourCNC god bless you:))

@Kadlukadloesen 11 лет назад

Ok it was the TIMSK1. Im using the ATmega32U4. Thank you very much for the answer! Greetings from Zurich!

This series are even more eductional than following a 500EUR course. Superb ! Doebi

Love your tuts!!!!!!! keep Them Comming!!!!!!!!!

@89rafa Hey, thanks for the feedback. I certainly will. It's good to know that it is important to mention those. I will be getting into timers and counters in more detail. The waveform generator modes (which are really terms of obfuscation) and others will be greatly detailed, mainly by example. Many thanks!

Your primary clock is set to a different frequency. Generally, at default, there is a prescaler applied to the internal clock and the chip will run at 1MHz. If you changed this default prescaler, then the clock will be running at a different clock speed than what is used in the video.

Thanks for taking the time and effort for making these videos. Really appreciate it. Keep them coming.

Thanks for these - currently studying AVR microcontroller principles as part of my Robotic Engineering Degree, and it's good to get some alternative tutorials on the subject. Also funny hearing your family life in the background there - i've currently got mine running amuck while i get on with my course work, so can relate! Good Work!

@PatrickHoodDaniel 11 лет назад

You need to find the correct usage of that register. Do a look up for timer mask in the datasheet. If should provide you with the correct number to use. By the way, what microcontroller are you using?

@PatrickHoodDaniel 11 лет назад

Thank you!!

U dint tell anything about wgm,timsk ........

@brianblasius 5 лет назад

I suggest you start teaching about using FreeRTOS on the STM32

@luigivestrolli3959 12 лет назад

Thanks for the explanatory of the source code. Exuse me for my english. By of Luigi.

I played around with pin change interupts, got everything set up and all worked ok. Then I added cli(); _delay_ms(x); sei(); _delay_ms(y); into my while(1) loop. My thinking was sometimes interupt would go off, other times it wouldn't, but interupts went off on every pin change with a delay. What is the best way to disable interupts so nothing happens after I turn them back on?

@Hainamcoi 9 лет назад

Better than my lecturer lol

@PatrickHoodDaniel 12 лет назад

@teradaci Thanks Giorgio!

@suvarupsengupta3853 11 лет назад

The tutorials are awesome ... I am just starting in the field of robotics ... and i am using ATmega8 ... Your tutorials helped me very much ... but the interupt conception is not clear for me ........ I just want to read a pin high and do a certain job on another port ........ HOW CAN I DO THIS ... PLEASE CAN U HELP ??? regards suva.

@Doebi Dady Thanks!

@midoitalia2010 12 лет назад

it's very good jop.. thanks man

@Catbangin 12 лет назад

Hi anajonesr, I love your microcontroller teaching..it is nice. it is very easy to understand. do you have cover video on how to code circular buffer?. i want to work it to generate echo. but i dont understand how it works. :)

@maulanawahyudi7127 3 года назад

Thank you :)) , By The Way When I put or add some extra code in while loop i can't imagine the plot or direction of code :( . Please help me give example for that, maybe dynamic change the value or something whatever :(( . Is it make parallel for ISR and main program ? When we try to run it together

@ACreativeWorks 6 лет назад

Hello if you could do an exclusive video with SPI communication, as comprehensive as the i2c, i don't mind paying again. Thanks.

@m4rt100 6 лет назад

hi brother! could you make tutorial about atmega multitasking without delay() or using timer as delay manager. thank you

@mikesterling3949 3 года назад

I tried to put this code in a .h (header) file, in order to be able to use one of it's variables elsewhere. But that does not work. Can you please help on this ? Example, I want to use > elsewhere.

@sirchikoz 11 лет назад

I am currently using the interrupt for RX in USART with ISR. How can I handle more than one interrupt type using ISR?Do I need to define multiple ISR routines with different interrupt vectors?

@sidmaurya3919 5 лет назад

Is there any software enabled Dead time insertion?

@Kadlukadloesen 11 лет назад

Hi patrick. Thanks for your very nice examples. My atmelstudio shows me an error. He say TIMSK is not a standart funktion and undeclared... He givs me a option from TiIMSK 0 to 5. but my led don't run ;( some idea? Thanks for evrything!

@akbaralam8683 10 лет назад

why u took 3 or operation with TCCR1B?

@xiaoyanli8572 7 лет назад

Hi I don't understand where about in the datasheet defines the internal clock frequency to be 1Mhz? Thanks

@PatrickHoodDaniel 7 лет назад

There are a couple datasheets for microcontrollers. One serves as a programmers reference and covers several microcontrollers with the same feature set. Another that is more specific to the microcontroller and is generally only a few pages long. That datasheet will have electrical characteristics and timing data.
