Add USB To Your Electronics Projects! - The USB Protocol Explained

Yo yo yo, for my uni project I need to implement an android app that will communicate to a gamma radiation spectrometer through otg usb. Gonna be hard

Hey! This chip only went up .03 since you posted this video! :)

That was the most detailed and useful USB tutorial I've ever seen.

micro controller with build in usb block inside is not a good variant. especially this one you show in this video. all you need is converter usb <> rs232 like CH340, FT232,
MCP2200 /microchip/ or some other from this days electronic company's. have a much in market. CH340 is in my work from 7-8 years. work any time on all my boards. also in new one in developing now PICKERPRO with pic18F47K42. believe me, even microchip pic micro device like 18F2550 that is used in PICKIT2 programmer is not good. usb inside in micro controller is bad idea.

Could USB (at least hardware layer) be used for a custom low power bus system with one master and many slaves?

How do you make devices that do not require a specific driver on Windows/Mac?

Everything is better with Bluetooth.

This video happens every 50 milliseconds while you have your USB plugged in. Whoa!

Very good. Thank's

"isynchronous"

This a solution for "hobby" things. However, if your board is going to be offered for sale, then you need to get it approved by the USB regulators. The FTDI chips are an option, but then when you plug it into USB it registers as a FTDI chip and not whatever your USB device is. This is a major limitation on USB over Ethernet or bluetooth.

Hi friend, please help me with a simple doubt (for you)!? How many VOLTS do we have in DATA LINE just plug-in a USB connector in the USB port of a computer???
I need just make 2 LEDs blink after plug-in the USB to show me the data lines (D+ and D-) are OK, please help me with this little project. 😞

Thanks

Im curious about that solderless adapter. Can you give some more information on where to buy something like that? Ive never seen one before.

is anyone need usb/hdmi/dp/hub cable? Thuder 4 cable also

Can I just add for the future, the breathing is very distracting. Not sure how to fix it either post recording or by breathing through your nose more, which might be hard if you have allergies, but I struggled a bit following since it's so prevalent. Great video besides that though.

EDIT: tbh just putting the mic further away from you (or getting a better one and doing that) might fix that since you sound like you are quite close to it.

Actually there are lot to learn in this tutorial than the topic. TFS!!

👍👍👍

I'd rather Wifify it.

i have a old led battery powered closet light that i never used cuz i don't buy batteries so i got a old usb cable cut one end off and soldered the black and red wire to the two main battery terminals and mounted it by my keyboard and plugged it in usb port on pc. now i have a night light for keyboard and it shuts off when i turn pc off ...

The absolute easiest USB chip to use is the Microchip PIC18F4550, DIP40! Plenty of examples, great datasheet, and applications notes. Been using these for years! No surface mount nonsense, either! An excellent book is Jan Axleson USB Complete, for those that want to learn and experiment.

Any idiot can use USB if the controller supports it natively in hardware and there are libraries for it. If you really want to show something interesting, then why not V-USB which runs on almost every Atmel AVR, because otherwise you can also directly use an STM32 with hardware USB...

Nice explanation with pictures! However, I don't think this is a way to add USB to your project, especially for a beginner. The fastest, easiest and cheapest way is to slap a USB-UART chip and not worry about code, protocols, libraries and anything.

USB is the bane of society. 'Invented' by an Indian guy, you can't figure out which way is 'up' without adding your own markings. But then, the receptacles can be just as dubious. And blind plugging is more often miss than hit.
Where was IEEE on this? Even the 'inventor' is caught plugging it in the wrong way and having to flip it... on camera while demoing it!
Piece of garbage, completely.

This was an awesome video!

Awesome video

What's the name of that smd adapter you're using? I can't seem to find it online

Great tutorial! You should probably mention that you mean "USB 2.0" whenever you say "USB."

I've used the 16u2, and it's a great chip. That said, the programming of the firmware is a colossal pain in the ass. I detest USD HID programming.

Ew micro usb

❤

Nice USB stick. Did you get it for free from a promo wink wink

Nice info, thanks for sharing it :)

Thank you! * subs *

I would rather use the blue pill for USB

What?

Great! Now how would one change those pesky WiFi devices to use Ethernet? For example the Sonoff TH16.
I need a remote smart thermostat on the building roof, and there is no WiFi AP there, so I would like to run a cable or use Ethernet over powerline.

I didn't know I needed this. Thank you.

Great explanation. Many thanks 🙏

I'm no electronics wiz, but since this would "supposedly" USBify everything, how easy would it be to add a USB port to an Amiga computer using your implementation? Would it mean utilizing the Amigas' serial port to do that? Thanks for the video!

If it's not a keyboard or serial endpoint, then you still don't have to write drivers for your PC. You can make a regular application that interfaces with USB hardware, like I did with a LabSphere spectrometer with proprietary communications (reverse engineered with Wireshark). I even did it in Java.

Ben Eater has an excellent video on how the USB protocol works.

It’s complicated. I didn’t understand a word.

Great video learnt a lot thanks
