I2C Frame structure Understanding | I2C data transmission

[@RajuBhaai-ue1ku]

haven't seen such a good animated video explanation. Good work!

[@FoolishEngineer]

Glad you liked it! Thank you so much for watching the video!

[@pcbworks]

Sure that it will be watched by millions in 2 years!

[@FoolishEngineer]

Thank you so much!!

[@jonathanfairchild]

Both of these videos are absolutely fantastic! Been trying to setup i2c on some microcontrollers and this has helped me understand. Thanks!

[@FoolishEngineer]

Thank you so much! Please show support to my video with Super thanks.

[@KevinJohnMulligan]

Your explanation was very clear and I really liked the toy car analogy.

[@FoolishEngineer]

Thank you so much, Glad you liked it!!

[@CienciaOpenSource]

Clear explanation, straight to the point and correct. Thank you very much for the video, I'm sure it helped a lot of people!

[@lone1derer311]

Great explanation and visualization! 😀 👍

[@mehmetdemir5655]

This is the only correct video of i2c, it is a masterpiece sir

[@NfcRfid]

Great explanation. I have rfid access control. It has one port vcc, gnd, sda and scl. What would be its function at that port?

[@PreludeSon]

The illustration is amazing, keep up the good work. Do you have DDR example?

[@simisongwenya2442]

This is great work!

[@FoolishEngineer]

Thanks a lot!

[@yametekudasaisensei539]

i didnt understand properly the example with the registers part, the byte of the registers means an adress for store the data inside the rtc?, because when sending more bytes in series how do know each byte to which register be ?

[@moinshaikh6684]

superb video I've ever watched in my lofe on communications, tons of thaks for makers efforts.

[@FoolishEngineer]

Thank you, please subscribe to my channel for more such videos!

[@ryderman5329]

aren't pin signatures wrong on this rtc

[@ShivamKumar-ky6vm]

hello one question , in order to read is it neccessary to send something first ?? like in your case parag gives guddu a car , can there be a case in which he just wants to talk to guddu and no gift given initaially ??? suppose in real world i want to read accelerometers data , do i have to send something to accelerometers and then read , bit confusing ??

[@sabilibili2271]

cause there are "more than one" data that we can read from RTC like day, time, months, etc so we have to tell the slave which data we wanna get from him. that's why we need to send "something" first to RTC.

[@ShivamKumar-ky6vm]

@@sabilibili2271 awesome thanx for replying

[@moinshaikh6684]

And please make More videos on embedded system, were here to watch

[@FoolishEngineer]

Working on it!! Soon I'll.

[@dhruvchoksi826]

I believe there has to be a repeat start in read operation which is missing in the explanation. Do correct me if I am wrong.

[@chetananam9141]

Dear genius "foolish engineer", you animate & explain very nicely! Great effort & great video! Please make videos on microcontrollers & arduino, raspi etc. Good luck to your channel with a million wishes for a million (& more) sibscribers!

@Foolish_Engineer can you post video for AMBA AXI protocol

[@mrunalahirao9256]

Very nicely explained 👍

[@ideamania9798]

I am using an IC for BMS, can you tell me how can we know whether our IC is communicating or not

[@kavithaseepana3855]

If two masters want to send the data at same time then how?

[@kishor_VU2MZT]

hello dear nice video ,,, i m not from engg background but made one project with Arduino Uno qmc588l and 16x2 LCD for azimuth sensing , its all work perfect with short length jumpper wire ,, once i connected qmc588l with 15 meter long 1 sq mm thick wire lcd display not showing qmc599l readings , how to fix it ? ,, my project requirement is to sens azimuth from antenna position from long distance ,, thank you

[@bonafontciel]

In minute 3:25 you say an interrupt is generated. Where is the interrupt generated ? Master or Slave?

[@FoolishEngineer]

Master creates the interrupt

[@SathishKumar-rh5it]

But how the initial slave address defined for the RDC IC ?

[@seifelkhouly9090]

it is a part of the ic data sheet,

[@paragsangtani3544]

Why in i2c data frame is always MSB why not LSB?

[@FoolishEngineer]

It is the standard rule Just like, we write address as 221B, Baker street, London, UK & not as UK, London, Baker Street, 221B

[@paragsangtani3544]

@@FoolishEngineer Really? generally we use LSB as operation why they take MSB isn't it weird....

[@FoolishEngineer]

@Parag Sangtani Hi Parag, Thanks for your question and following our channel. Your question seems valid but I couldn’t find an exact answer for that. What I am referring to is, this spec sheet www.nxp.com/docs/en/user-guide/UM10204.pdf . In the byte order, they just mention that MSb first. I feel, maybe internal shift register of I2C devices is configured to send MSB first. I hope you know that in UART it is configured as LSB first. If you feel our answer is incorrect and you get some reference to that, please feel free to share that with us. It will surely help us!

[@FoolishEngineer]

For an example of shift register placement, Please refer section - Data transmission of this wiki page en.m.wikipedia.org/wiki/Serial_Peripheral_Interface And please check the first diagram and it’s shift register placement which makes MSB out first. I wish I could draw here and explain to you in detail. Still, it may give you an idea of how to shift register are placed in any slave device.

Can we connect 50+ relays at a time to I2C Can we control all of these relays ?

[@FoolishEngineer]

Yes We can,

Master put address to I2C bus. Then corrosponding slave identify and match with his own address . Then slave say Hi to master ( send ACK to master) How slave match address which is send by master . Which register compare received address and its own address . Thanks.

[@jonathangra-v6l]

Super

[@timse699]

well done!

[@FoolishEngineer]

Thank you so much, Glad you liked it!!

[@mathewm3419]

When the address Matches with a slave in multiple slave scenario,will the other slaves remain shutoff until stop command? How is this achieved?

[@FoolishEngineer]

have you faced this in your design?
