Very nice Video, Understood many things. Thank you very much

[lousaileong]

Thank you . I was searching several videos and your video explain definitely much clear!

[hemanth_loky]

People get enough information in a short span of time, after watching your videos. Really useful. Thanx a lot. You're really great! Love from chennai. :)

♥

[StreuB]

This was so well explained!!! Thank you!

[mrmilan]

No any word.. Only Fantastic.. Fantastic.. 👍👍👍🙏

[RafyoMusic]

great video!
So easy explained, thx a lot!

[Shiden]

I understood one chapter of Computer architecture in 10 min thanks bro!

[mforrest]

Wow you are really good at explaining stuff like this.

[shakthianistonshakthi]

Yes really nice video thankyou for ur effort

[rakeshgiri]

You are best than college professor easy and understandable, ❤🙏🙏

Really a nice video about the basics of UART protocol, i would like to highlight few points regarding this:
1. Communication b/w two devices can happen with just 1 wire/line also. So no mandatory need of two lines always i.e. Rx/Tx.
2. UART data/char/word bits can range from 2 to 11 also 12 sometimes, this is configurable entity in modern uPs and uCs.
3. There are several encoding schemes supported by UART peripherals like NRZ, NRZ I, RZ and meny more, again configurable in HW, so not always 0/5V logic pairs(at UART level).
4. Handshaking mechanisms are also supported by UART peripherals in built sometimes like HW Flow Control and if not can be taken care in driver SW using software flow control mechanisms(using XON/XOFF chars).
Thnaks :) Happy Learning :)

"I hope you got something from this." Barely got what I needed. UART = Serial at TTL voltage levels and without extra pins. All I needed to know.

Really a nice video. One point is that in the computer and printer example...yes it is low to high voltage at computer side and high to low voltage at the printer side during data transmission from computer.
But when the printer sends any response/ acknowledgement/handshake data to the computer, it is vice versa, which is not explained in this video.

Do you have one about the X and Y capacitor in switch modesz?

[SanjayjiTingilikar]

Good explanation ... Keep up the good work.

I am looking to purchase a universal UART hardware to reverse engineer firmware used in an array of main boards used to control ASIC Crypto Mining Hashboards... What hardware do you recommend?

[teaguehall]

Overall good video. Maybe some areas to expand on: What does asynchronous mean in UART? (i.e. no dedicated clock signal is used, thus each client needs to agree on the baud rate ahead of time). How does the parity bit get used in practice? If a corrupt data frame is received, is it just up to the receiving client to ignore the data?

[andrewsotnikov]

Good video.
Actually I could not umagine rs232 transmit data at high voltage range

[surenbono]

.. remember if tx can send 9600 bits/sec...the rx side can only store 640(64bytes) bit per receive...so it need ~ 15 tx msg / second to receive 9600 bits..for Arduino..not sure about other hardwares..

how to interfae uart with microcontroller and also tell the hardware connection 0f uart
