456 Hassle-Free ESP32 USB (ESP32-C3, ESP32-S2, ESP32-S3)

The USB feature of the new ESP32 chips is handy. Unfortunately, it is not easy to use because the information is hidden. This video shows how everything works and how you must set up the Arduino IDE to exploit the USB functionality. I promise it will save you a lot of frustration and time. And it is the basis for a future video about simple debugging with the new Arduino IDE 2.0

I have not said it before Andreas, but I look forward to : the Swiss accent, The little hand pointer, The hat and the knowledge You share. ThankYou Sir.

[emiljagnic]

Man, I love your existence Andreas. You have no idea how much you can help an undergrad mechatronics student understanding these electronic specifics for embedded development. One day I wish to be like you. Have so much knowledge in all the electronics areas of expertise.

[chipko]

What a fantastic video! I've had some frustration with the basics on the S3 boards and whilst I don't have as many now, you have just answered many questions I had!

[daveb]

Your measured and clear descriptions make learning this much easier. Thank you for another useful lesson, it's appreciated!👍

[cheaterman]

Can't wait to see your JTAG video :-) I've always been intrigued by it, I always thought it was some sort of standard programming port (as it seemed to me that's what it's mostly used for), but can't wait to hear you go into the details :-)

It not only can act as a storage device, but it is possible to programatically service block reads and writes. In theory, one can proxy it over the network into a file on some server for infinite space.

Thank you for confirming USB Host mode is not currently present. That was a real head-scratcher when I bought a couple of these a month ago and had to abandon a project.

Would have been great to have had this functionality from day 1, but glad I didn't waste my money, cheers!

I knew about half of these -- thanks for the comprehensive examination. One of the things I learned was that the C3 had the CDC Mode -- I was, for some reason, thinking that it did not have any integrated USB functionality at all.

Looking foreward to your hopefully next video on the JTAG aspect. Would be nice if real HW debugging would finally be possible!🎉

Thanks! This was the final step in my prototype mini ffb wheel. I've got the device recognized as a 1 axis 0 button joystick and the rotary encoder drives the axis input.

GPIO0 the most important GPIO there is, hours of frustration can be solved by this pin! Thank you as always nice clear and to the point.

[ikkentim]

I couldn't find any concise info on ESP32-S3 and this helped me a lot, thanks!

[Zhaymoor]

Just a notation for everyone trying, for the first time the CDC On boot mode isn't enabled by default; so it must be enabled and any sketch should be uploaded over Serial then after that you will be able to upload over USB.

Thank you for the amazing video Andreas

[mindshelfpro]

Awesome video. Nice explanations. If I had known a few months ago I would have skipped WROOM-32 and got -S3 modules

[simolx]

It's amazing how your videos have solved so many of my problems, Thank you Andreas

[TYGAMatt]

As mentioned in the comments, MCPWM using the Arduino IDE would be a cool video.
Another idea is the pulse counter, as that isn't simply available in the Arduino IDE but would be very useful.
Something to work on during your summer break! 😊

[imoverclocked]

Thank you for this video! I have been banging my head against the wall with an S2-mini board just to get serial print statements. The newer Arduino IDE and the "USB CDC on boot" parameter was the final hint that I needed.

[arp_catchall]

Thanks for the video. Please make more about esp32 features and such, especially the esp32-s3. What I love about your videos is the originality. Seems most utubers just copy one another... Waiting on your debug video mentioned here.

[drstefankrank]

I used the S3 chip in a window sensor design using a USB-C port for programming. So much more convenient than hooking up RS232, especially when they are already glued to the window frame.

[ikaruseml]

Thank you man with Swiss accent, what you explained solved many problems in my mind.
