A little correction/notice: The debugger shown here is not a "true" hardware debugger, but an instance of GDB in combination with a little mediation program on your Arduino called a "stub". This means that a small portion of your uploaded firmware is only there to establish a connection between your internal program states and the serial terminal. This explains why starting the debugger is part of your code (see debug_init()) whereas a "true" debugger would manage all attachments to your chip from its own peripherals. You could say, the firmware is "aware" of the debugging when using a stub. This also means that a bit of memory will be inaccessible to you, because the stub needs it. If you were to upload a program that uses every byte of memory, you wouldn't be able to debug your program anymore, so keep that in mind. And even more so, since the stub uses serial, any printing won't be available. Happy debugging!

I've been programing microcontrollers with arduino and platformIO for YEARS, but I wasn't even aware this could be posible to do. Also, great video, keep up!

This video deserves a lot more views. Alone his presentation skills are pure gold and very entertaining.

As much as I hate UKposts algorithms as well as this platform, this time I was absolutely blessed with coming across this video. Thank you my dude! For quite some time I was thinking about using some normal IDE for Arduino projects, but was too lazy to actually look it up.

Such a great channel providing simple and useful knowledge... Feeling good to be your 23rd subscriber. You have my support ❤️, Please keep making videos like this. 🔥

A minute into your first video and I hit the subscribe button. Love your comunication skills, just the right amount of humor and explaination speed. Some of these you-who-tube creators talk sooooo slow... I guess they don't think I can hear very fast. You're awesome and thanks for posting!!

Just got recommended this video, wish you luck in your youtube journey!!

You made my day!!! Was just about to spend some more money for a EDBG device. Now I can afford to buy more tea... GREAT

I like your presentations a lot!

Like your style. Hope this channel becomes big.

Excellent!, thanks for asking the hard questions, why isn't anybody talking more about this?

Excellent mate. You have talent please make it your daily job !!!!

short and to the point, that's the way I like it

Bless Jdolinay, and Bless you. It's amazing!!! I need it that! Thank you

Stepping through your program and adding breakpoints is a great start. But where do I view register contents, flags, timers etc etc ?

Personality plus Mr. J's. Interesting programming direction using Visual Studio Code and Platform IO. You have my attention J. I might just try it. Thanks.

Thanks for sharing this

damn who would have thought I'd be genuinely laughing while watching an arduino debug tutorial 🤣subscribed

Best arduino tutorial ever 😂😂😂😂😂😂😂 You nailed it mate. 🎉

I wasn't aware of this, I'm not using the nano much lately because for a similar price there are far more capable alternatives but it is definitely a nice tool to have.

The most useful video I've ever seen, thanks 🤩🤩🤩🤩🤩🤩

I'm glad it wasn't just me. I recreated exactly the start of this video just scrolling through google results trying to find some sane guide on how to debug and getting nowhere...

Gracias !!! Realmente lo adoré !!! Gran Vídeo !!!

While I do own an hardware debugger aka the atmel-ice with J-Link on backorder for a year now. This an easy way to debug for smaller projects. For a very complicated I wouldn't chose avr stub.

Great! I've developed a whole project without knowing this was possible. As I got my UART port busy -which was my board main communication channel with other HW modules- I had to use a separate arduino as SPI-UART gateway, and sending those kind of "enter function 1!!!" "enter if" "enter else" texts over the console. Having known this, probably i'd have chosen another way of communication, freeing the UART for debugging. I also wonder why this is not ~basic primitive~ stuff along Arduino community! How can a novice learn without debugging? Thanks again for sharing this information.

i hve tried using platform iio before ill try it again thanks for video

Just getting started , I don't know what he was doing but sounds cool

Thank you, is a big help to me!

Great thing. The debugger is especially important for beginners who are struggling with trying to understand the internal intricacies of how Aduino works.

good presentation. sure, it works great with simple projects, standard libraries and standard cores but using it with complex projects fails more often than not and the configuration settings are a mesh.

amazing thanks for the help

I spent 20 years learning C++ so I could debug it in my head, when I could have just done this.

36 subscriber, what a wonderful video :D

I think you just saved my life.

There's one hidden problem with this approach: is that it uses serial. Yes, the same serial many use to print out stuff or for communication with PC. So in case you need to debug and print to serial you will need a second arduino in passthrough mode (reset shorted to ground) and a bit of config definitions in platformiotxt.

What a great video ..... but never once have I managed to make this work! I'm on a Mac, I might try on a PC in case that's the problem!

Very nice but a couple HUGE catches - serial port conflict mentioned previously AND breaks in SETUP are INGNORED. Inching closer to Atmel Studio every day

Amazing. Can I do c# too, or is that too much to ask?

It's an ant, not an alien. Originating with the author, Ivan Kravets and his work with SmartAntHill.

hwy ? May be due to the footprint in the memory for debuginf stack .. But it's is very interesting tool set

That is remarkably simple. I thought you'd need to get one of those extra serial debugger modules to do this. I had no idea it would work out of the box. I wonder how many other devices you can do something similar with?

How many resources (flash & ram) does it use & can you look at vars, registers and the ASM?

pretty cool bruv 👌

thank you! I need to use this debugging naw 😊

The 'So install this super useful library by *struggle to pronounce name*, anyways bless him' pretty much describes the entire open-source communinty

Very cool ... thank you

Hi, a breakpoint is usually used to read out the content of some variables, to understand where a mismatch in our coding is coming from. Can we monitor the value of variables with this "debugger-like" tool? I guess not..

Toller Tipp, klasse Video. Vom Erzählstil her ein wenig wie Marti Fischer. Gefällt mir :-)

Will this debug work with ESP32 based chips & dev modules? I'd like to hear more about using it with these ESP devices ( if it's even possible) .

You're actually really funny. Love it. 3:59 😂

Hi! So.. i have a question. In the first step you said to take arduino ide and throw it out of the window. How can i do that? i mean, i guess i can take apart my ssd and find where arduino files are, but i dont think that is the best idea.

How to setup the DUE for debugging?

how can we debug stm32 microcontrollers

you remind me of one of the hackers from the film skyscraper on netflix

Just boards with the 328 chip? Is there a way to use platform IO with other boards and get debugging? That's pretty freaking limiting...

Thanks for the amazingly simple tutorial and the bits of comedy =P. If anyone is looking at this tutorial trying to use the same process to debug a Seeduino Nano device, you have to change the "env:" and "board =" fields to "nanoatmega328new" Also, if you are getting some issues with entering debug mode concerning "libncurses.so.5", just run this on your terminal: "sudo apt-get install libncurses5"

Have started with esp32 and do not know much about arduino but how common is that ATmega328?

would this work with expressif nano esp32?

Do you know if there's a tool to debug Arduino Nano 33 BLE? Cuz the microcontrolller it uses is not an AVR so I can't use this tutorial :(

thx, looks like cool. But does default debugger so bad? *find answer* it is strange, but it is not default feature of MC, you need or external debugger device, or MC with built in. Really strange, because there are all capabilities for communication. Anyway, that arduinos that has ESP32 has this ability in WIP, so I hope it will be able soon.

Quite cool, but it is still some kind of BS but not that big as Arduino IDE. Solution to this is to buy Pickit4 or Snap or ICD4 and import arduino project to MPLABX. Works very well on ANY atmega. Of course compiled program doesn't have bootloader anymore, unless you specify proper memory offset for compiled binary, to preserve that bootloader area and load bootloader binary during flashing as well. That way you can go back to Arduino IDE if needed. Or you can wipe bootloader and then restore it with programmer.

How do we install libraries?

There's a new arduino ide that comes with a debugger. I was hoping that the video was about that. Good video btw i leave at thmubs up

"Don´t be scared if you see this. Run.." (6:12)

anyway, this is f** amazing, thx bro👍

Hello , very interresting and simple. But it's Ok for your UNO or NANO. Do you have an example idem For ESP32-S3 witch include Board JTAG ? Thank You Very Much

Can you inspect variable values, if not, it's kind of useless?

could it be made to work with uno_r4_minima ? or do you know any software-only alternatives for this board?

Hello , i'm getting the following error: vs code could not find the specified task please help.

Wow thats amazing. I actually came across people saying there is no debugging available for arduino uno or nano. How come is this thing even possible?

Is there a miracle chance that it works with esp32?

Such an excellent explanation. Maybe you could guide me on this problem: Error: Could not find the package with 'jdolinay/avr-debbuger @ ~1.4' requirements for your system 'windows_amd64' .... and so #include's #include #include fail . Thanks anyway ! Greetings from Buenos Aires.

This looks great. but I haven't been able to make it work. It compiles well. Uloads well and the it says .pioinit:13: Error in sourced command file: COM9: No such file or directory. Can you help me? Thank you

Excellent presentation! How can you NOT subscribe?

The only time that i have needed debugging like this was on an arduino mega (about 3 years ago). I have adopted putting serial prints into #ifdef debug with a #define debug to make it easy to disbale and enable anything used for development by commenting out the #define. the other nice thing about this, is it allows you to have multiple types of things sent if you have mulitple #define for various things. So you need data for calibration #define calibrate - then put the serial prints inside of an #ifdef...#endif. Need debuging type stuff, uncomment #define debug. Neeed calibration, uncoment that. need both - you know what to do.

Nice

Can use the same debugging tools for ESP32 (Arduino framework)?

What about ESP32 or ESP8266 ?

Haha nice video.

An error occurred like "COM11, No such file or directory" I solved the problem by changing "COM11" to "\\.\COM11". Thanks for helpful video.

What about variable values?

Crazy

...."Nobody is talking about it"... Because adults in the room use J-link (J-tag) instead which affords a boundary scanner as well. Once you use it you will never want to go back.

Waaa Thanks

This is simpler than debugging the ESP32 with the ESP-Prog. Why doesn't Arduino advertise this?!?!

Using micropython seems debbugable as well

How about in micropython, pls 🙏 I used to print("blah blah blah... ") to find out - how far the code worked .. hhahaha

Such a shame, this does not work, gives error "Could not find the specified task." Are you really doing nothing else behind the scenes as have checked your vid slowly through to make sure all the syntax I have taken from your info is correct and still the same error, and yet your demo works, how can this be ????????.

You complain that other solutions hide the debugging behind another tools. But then continue to represent a tool that does the same.

Sorry, but not working :( Could you help me please in private?

muhahaha,great

Oh, my god! I think he said "microsoft" . I think, i will delete the internet.

this is not debugging !!!!

First of all, never code in arduino terms, only use anscci C, because in time critical applications you will have a large issue, Second, you will never have accesses to registers view, whitch is fundemental for debugging professional, so dont use this method, bye an Atmel Ice, get rid of the arduione bootloader, and code in Ansci C, the only way to do this right

Don't over act and you may grow.

OK!! Tru To program a Hybrid..And Understand Librarys...??!

i really wanted this to work. debug not available for the arduino uno on the arduino ide. followed your instructions:- Configuring upload protocol... AVAILABLE: arduino CURRENT: upload_protocol = arduino Looking for upload port... Auto-detected: COM5 Uploading .pio\build\uno\firmware.hex avrdude: ser_open(): can't open device "\\.\COM5": Access is denied. it works fine from the arduino ide.
