- The complexity of a USB interface makes the old school asynchronous serial UART interface attractive to embedded system development. In this video, we show how the USB to UART bridge works, how to install a Windows driver for one of these bridges, and demonstrate a connection to an ESP32 evaluation board using the CP2102 bridge. We also demonstrate the operation of a watchdog timer trying to recover from a non-functioning operating system.

I have no clue what any of this is but im glad you managed to upload this for someone who has the slightest clue what any of this is. I dont even know where to start to get the knowledge to understand even a quarter of what is going on.
I think you should start with arduino online course for beginners.
This was an awesome video .
Waiting for next episode.
Thank you very much professor. I was waiting for your new video! Super useful content!
Excellent!
Thanks for sharing.
Wooow great my favorite esp32 gonna be your machine i am so interested to know something new about it .. i really thank you professor about you great videos which spreading knowledge to the whole world for free .. i am from egypt and i really thank you about all the great knowledgeable information .. fr my deep heart thank you
Thank you for sharing this content!
Maybe my thoughts are really a non sense topic, but I wonder what would happen if you try to plug a USB keyboard DIRECTLY to a USB-TTL converter. Why nothing happens and if there's a way to create a hardware (a bridge that doesn't need a PC to interface) that initializes the keyboard (you said the host need to start the USB peripheral) and then starts converting the input.
Thank you for realy high quality video and very clear explanation. Do you know maybe if it is possible to convert USB keyboard to uart with this bridge? I have small keyboard that has only 4 buttons (arrow keys) and I want to detect which one is pressed on my esp32
Hello! I was wondering if you tutor ? Is there any way to contact you ? Love ur videos !
