PROTOCOLS: UART - I2C - SPI - Serial communications

[@avishjain4226]

That was a nice explanation! However, I want to mention few things 1. I2C is Half-Duplex (not Simplex) 2. SPI is Full Duplex 3. In I2C, we can configure the peripheral to both the modes - Acknowledge and No Acknowledge

[@elhoward7440]

SMBus and I2C are slightly different protocols using the same hardware. Isn't No Acknowledge actually SMBus?

[@AMG-gc4io]

what is I2C Protocol in Arduino Nano ?

[@knuckleduster05]

@@elhoward7440 no, ACK and NAK are both part of the I2C addressing protocol. When you write to a slave, the slave needs to pull down the SDA line to ACKnowledge that it is ready to receive communications.

[@thekitsunedev_hun]

@@AMG-gc4io Its the Wire.h library and the same pinout as the uno (A4,A5)

[@ksawery6568]

Also, I don't think you say Bauds/second, as 1 Baud = 1 bit/second

[@savage8336]

This is honestly one of the most helpful videos I've ever watched. I wish I saw this in school a few years ago.

[@mugglepower]

fuck schools man schools never teach you shit. of the 100% of content I learnt from college(in which my major MATSE is top 10 in US) probably 15% of the shit is actually useful. rest they just make you jump through hoops and run in circles and chase your own tail. I talked to professors and very smart people(well, smarter than me for sure) and they all tell me they purposefully make this shit difficult. I picked up more programming stuff in a month with my flipper zero than an entire semester worth of programming courses in college/. by the end I finished my college programming class i still have trouble fucking printing hello world but with interest and a bit of self learning I'm writing sql now.

[@robdoggitydog255]

[@dontstop_fun6]

Since long time, I was searching for such an explanation and today by your video my concept got clear about bauds transmission. I'm really thankful to you for that.

[@dikshitadesai]

I so appreciate you elaborating these concepts on the circuit boards. That literally saved me hours of hustle. Very well explained! Thank you

[@cmfanz]

@electronoobs, just a little correction needed in the table at 10:27. I2C does have an acknowledge system. The slave will pull the SDA line low when it has successfully received the transmission from the master. This will show up as the last pulse that appears after all the data bits are transmitted. This last pulse will be a high if the master does not receive an acknowledge from the slave. This way, you can clearly get a confirmation of the handshake.

[@fldr4362]

what a tutorial! wow thank you my friend!

[@lincolnkarim1]

Very clear explanation. If I may suggest--It may be worthwhile to draw the vertical sides of the pulses slightly slanted to remind us that the pulses are not ever square, but it takes time to climb from low to high and likewise to fall from high to low. I believe that the counting actually takes place at the middle of the slope (zero crossing) of the leading and trailing edges. Thanks for taking the time to produce this video.

Great, this video is more helpful for everyone. your way to teach is totally awesome.

[@AntoineAshraf]

Very nice video, just a few things to note - UART can work in both half/full duplex modes - There can be more than 1 stop bit in UART in some cases - I2C is a half-duplex protocol - SPI is a full-duplex protocol - The concept of acknowledgement in I2C is based on whether the slave is ready to receive data or not, so it's not applicable to generalize the term over I2C.

[@sanderd17]

Serial is slower in theory, but in practice, it's very hard to match the different bits up when using parallel communication. The faster your clock, the harder parallel communication becomes. With the clock speeds we have today, serial communication is without a doubt the most stable and fastest way. You can also double a serial link by doubling the wires. But unlike in parallel communicating, you don't have to synchronize the bits, you only have to synchronize after large portions of data have arrived. The fastest serial links (like gigabit ethernet, and USB C) , now use multiple wire pairs for serial communication.

[@benhetland576]

Speaking of "bauds per second" is actually not very useful in this context, because the term "baud" itself actually means "state changes per second"! (Thus bauds/sec would technically be the _change_ in the rate of communication.) A change in state of a communication line may also - and often does - represent more than one bit, although for I2C and RS-232 it does indeed represent only 1 bit per (potential) state change, so its baudrate equals the bitrate or bps (bits per second).

[@kuukatti]

And also, I2C does not need to know the baud-rate beforehand, that's why we have a wire for a clock.

[@alteriaautomation6867]

yeeep

[@remus-alexandrusimion3439]

In most digital communications baudrate is bitrate. The difference applies to analog communication, where phase shift and multiple amplitudes can encode bits. And yes, all sync communication can lack the bit rate information since the clock establishes the bitrate. It is however usual to establish some margins for each device, and if master is outside those margins errors can occur (usually due to hardware timing restrictions of some other kind).

[@hansdegroot652]

So i2c could do adaptive baud rate? In theory at least

[@yasirrakhurrafat1142]

​@@hansdegroot652 i think you could develop a program on the sending and receiving device. That'd send a signal to the receiving device to change its baud rate (on the receiving device). On the uart communication system as well, although it'd take its sweet time for the changes to take effect. As for the i2c, itd be just about instantaneous. Soo, yes.. theoretically you could have adaptive baud rate on the i2c, although I think a predetermined, static rate should probably be more efficient and stable.

[@pritamnath7098]

Thank You Sir. My concept cleared about UART, I2C and SPI communication through this video

[@jonasduell9953]

Well, this sums it up greatly. I work a lot with digital signaling via I2C which usually come in a 4 pin layout, GND, VCC, SDA and SCL since active devices need an additional power source. Anyway, great content, subbed

Thanks, this is really the best explanation online.

[@UFO_researcher]

Very nice video, thank you very much. It is possible to have two-way communication using simple RX and TX also known as UART. You could use mosfets as a gate and activate them using a digital pin on an Arduino to initiate send or receive. This would also allow you to have several devices connected using the digital pin and mosfets as a selection mechanism. You could pass the signal directly through the mosfet as if it were a switch. A 2n7000 would be a good choice for this. The Arduino would activate the mosfet gate capacitor, then the signal would pass through the drain and source of the mosfet.
