Fundamentals08 I2C Protocol Tutorial or How I2C Protocol works
Friends welcome to this video series on Embedded System. In this lecture we are going to understand everything what we need to know about I2C protocol. We will start with the highlights of I2C Protocol and then we will try to understand open drain or open collector concepts, I2C frame structure, Arbitration and clock starching and finally Advantages and Disadvantages of I2C communication.

Hello Malcolm Hodgson, Thanks for appreciating the work..:)

[@Mrkn528]

Very good presentation. Few things missing in the video.
1) Start bit/condition: SDA high to low when SCL is high.
2) Stop bit/condition: SDA low to high when SCL is high.
3) Data change on SDA is only allowed when SCL is low except start/stop conditions.
Agree?
Thank you..

In general, I2C communication is the mutual communication between ICs and ICs on the board. If there is IC and IC communication between boards, what are the advantages and disadvantages? How stable is the communication?

Nice video...thanks

[@TechVedas]

Thanks 👍

[@ajaynikkam1801]

Sir theoretically it's good but can you make one video on i2c in that video i want to learn coding about i2c (Master and slave)

[@TechVedas]

I will definitely cover coding videos for UART, I2C and SPI

[@ajaynikkam1801]

@@TechVedas ok i will wait for that

[@SureshKumar-nk2ok]

very simple explanation to understand better especially transistor concept,sir how can i practically implement this

[@monimonish302]

Can u ans me for this question ⁉️
Question is how to choose the mode in i2c I meant "fast mode ultra fast mode" these modes.
All people said depends on application,that I knw but I want CLR explanation for what kinda of application I have to choose respective modes?????

[@georgevengal]

very helpful

[@TechVedas]

Hi georgevengal, Good to know.. Thanks..:)

[@jancenj2218]

In basic serial communication, does it send the start bit first then the MSB then LSB then the stop bit. ?

[@shubhampatil4666]

Thanks a lot Sir and please make a video on RS232

[@TechVedas]

RS232 is the line driver used for UART communication for the devices operating at different voltage levels. I will try to cover UART hardware and software in the next video.

[@ajitgawade5648]

Thanks for this informative video. Can you explain with an example such as MCP 3426.

[@TechVedas]

Hi Ajit, I have already made videos on UART, I2C, SPI and their configuration on STM32F4 microcontroller. You can check this series which consist of all videos: th-cam.com/video/GjMW1zqyTOk/w-d-xo.html

[@kranthikumarreddy245]

Hi,please let me know how to decide whether to use pull up or pull down resistors?
How to find the resistance values for different communication protocols?

[@sanvimanikommukuri268]

pull up

[@aejazbasha5397]

Can you explain what is the repaired start concept and what is the use of that

[@saisrikargollamudi7892]

7:09 Sir, Master 2 should lose arbitration after LSB itself as it sent a 1. Am I right?

[@rahulshettinaik8854]

😍😍😍

[@rahulsutar9042]

Please make video on ddr,ddr2,ddr3

[@axramar7743]

Can you help me with i2C coding with MS51FB9AE and MLX90614 ???
MLX90614'S Default Slave address is 0x5A
Address to read Ambient temperature is 0X06
Tried to code on it using KEIL but it's not working, but I am keep on getting 255, what might be the solution for this problem ??
If I use 0x00 instead of 0x5A for same Ta = 0x6A, I am getting some values like
173,29
174,30 etc, (I'm reading two byte data)
Please Help here !

[@rezaashrafip.5650]

7:35 master ...? Didnt get the word! Overally it was a good tutorial for beginners like me

[@somashekarswamy8509]

11. Write a Verilog code to implement the I2C protocol.

[@thezombieguy426]

What if all the Masters are sending at the same time to a single slave which obviously had the same address? Which master wins in this case?

[@ArchanaSingh-pu8ch]

Can you explain how second master win..even though it send 1 at the start.

[@paragsangtani3544]

I think winning master will be master-1 because the information that is provided in NXP i2c manual(UM10204) it is clearly written that if master will try to send one and detects zero then it losses bus control so at 5th bit master-3 losses bus and though master-2 losses control in starting bit only. If in whole they transmit same bit then transmission happens without an error.

[@rajeshkumarvanteru4958]

what is test case of i2c protocol

[@Legendsgoku123]

can you please share a code for interfacing mcp23018 to pic 16f877a which is i2c communication

[@govindkrishnag2477]

7:03 Master two should lose arbitration in 1st bit? Am I Right or Wrong

[@architjoshi2199]

I think he is considering the signals from right to left. That is why master 3 loses the access followed by master 1.

[@sahibalam401]

data framing is incomplete. internal registers address is missing in the frame

[@KeithMakank3]

DAT intro music

[@kongyuebanshan6400]

Can you add subtitles?

[@karuppasamym9616]

Bro there is small correction....for 7 bit addressing....it supports 2⁷ - 1 = 127 slaves. Similarly for 10 bit 2¹⁰ - 1 = 1023 slaves....becoz 128 represent the 8th bit, similarly 1024 represent 11th bit

[@mdmustaq6960]

In the video he meant devices with address 0 to 127 implies, total 128 devices. You might wanna rethink your logic !

[@ninjaassasin6388]

2^7 = 128,
We take 127 when we include '0' too, but here we are not considering 0.
We are counting from 1.
Therefore, it's 128 devices that can be connected.
However, out of these , 8 are already reserved, so we can actually connect 120 devices.

[@jackevans2386]

Description is in English, but he narration is done by Apu from the Simpsons.

[@theflamecoreguy7929]

😂

[@kavanpuranik98]

So ... It's an isekai?

[@aravindpalat7673]

what will happen if we dont use pull up resistors ?

[@RwP223]

Voltage signal will float low causing headaches, there needs to be a small amount of V potential via the pull up resistors to hold the signal high.

[@BBRR442]

uh feel like there is a lot of missing information

[@kenawykenawy]

it was invented in 1982!! check your facts man

[@kongyuebanshan6400]

In general, I2C communication is the mutual communication between ICs and ICs on the board. If there is IC and IC communication between boards, what are the advantages and disadvantages? How stable is the communication?

[@wayland7150]

It's usually communication in the same enclosure. It's only 3.3v so not for long distance. A typical 2nd board would be a small display like LCD or OLED.
