LESSON 29: Dos and Don'ts for Arduino Software Interrupts

You guys can help me out over at Patreon, and that will keep this high quality content coming:

This lesson is a follow on to the tutorial in lesson 28. In today's lesson we discuss what to do and what not to do in programming software interrupts on teh Arduino.

Thanks Paul, I'm working my way thru all these earlier tutorials, mainly for the functions, if/else statements and Interrupts and other good lessons you provide....

[paulmeistrell]

Thanks for the quick lesson Paul. Something else to use is the boolean "not !" to cut down on service time.

I am trying to build the distance measurement with ultrasound 1st time for my last year undergraduate project. Thanks for the tutorials

[Aridzonan]

Thanks for the tip. Had a delay in my interrupt loop. Got it fixed in short order. Need to break out of the main() to read a thermostat.

Awesome Work, , really good tutorials. There's only a few lessons I haven't seen ( lesson 21-26) but have you covered functions, libraries, and real time clocks so that we can quickly implement them? I'm kinda being selfish here as I could go search around for someone else's work but often times many video presenters assume to much background knowledge, the camera is moving around, , or there's music to entertain us which all seem to detract from a good learning experience. Your, , this is what it is, , this is how to use it, , method without going into register etc etc details style is excellent for educational purposes! Enjoy the show!

Paul is really amazing, i do believe that like this man can make a great invention.
Carry on great man, you are the best.

Thank you so much for your work. I would suggest you new topics: I2C, arduino communication with integrated circuits, filtering. Thank you again

Thank you Mr. Mcwhorter. Cleared up the questions I had. I was thinking of using an interrupt for a OLED display for feedback on a spwm sketch... now I won't lol

Good day to you sir all the way from Greece.

[charleswindsor]

Thank you I found this lessen and Lesson 28 very helpful

[andrewferg]

Thanks! You answered my questions in this video!

[sarfrazalam]

You're really a good tutor . Why don't you make a tutorial videos on avr microcontroller !! Hoping for positive response .

[pareshmhatre]

Mr. You are real hardworking Robot among us!

[mafiaboy]

Can't wait for the next lessen
this info helps my 10 miles long

[niceday]

The dislike must be envy the talented kind tutor, the lecturer is a true master.

[mcpojack]

Would be interested in a NodeMCU tutorial possibly interfaced with a weather station type application. Love your tutorials, I have learned a bunch!! Please keep up the good work. I follow your Fusion 360 stuff also since I am a 3D printer buff. Too many hobbies!! 3D printing, CNC, Arduino, Drones, etc. etc.

[mohamedalsada]

You are amazing..
Please please continue the Arduino lessons part <3

5:22 It might seem like it's ignoring the delay but it's not. It's filling up the stack with each interrupt call that are overlapping. If the interrupt calls happen so frequently that the servicing routines take longer, the stack will grow and grow until you get a stack overflow.

Verry nice helpfull to me, Thanks a lot

[twainstasiuk]

Really good lessons on interrupts! I've used them from snippets but honestly never really understood what I was doing or how to make my own, , , now I do! All of a sudden the reference pages are easier to read at Ardunio.cc. Hahaha, , awesome and thank you for yet another quality teaching video! :)
