Hello! great presentation. What is dual spi different from what you described?
Oh men you carried me so hard for my computer architecture exam 😂 Thanks! Keep going with your videos!
Thank you so much, Glad you liked it!!
You said that the chip select is an active low signal,which means its duty cycle is 0%. So how is it to the Vcc level?
i want to insert a chip in the SS line. the microcontroller should pulse an address and the chip will multiplex the SS lines. i think this is a much better solution, given the specific application latency requirements do not prohibit it
Doubt in the modes and clk phase .
Keep going, visual representation are very much helpful 🔥 big fan sir
Thank you so much, Glad you liked it!!
Nice and Clear, thank you!
Thank you so much, Glad you liked it!!
I really appreciate your efforts and dedication bro 🔥, for such detailed animations and explanation.
Thank you so much 😀
Amazing work brother. Please do AMBA soon❤.
Superb explanation bro, which software your using to do animations
Thank you so much, Glad you liked it!!
I use After Effects
Communication between 1 SPI master device and 1 single slave SPI device generally always works well. But as soon as there is more than 1 slave, it's a big bazaar !!! Arduino libraries like SPI.h, + SD.h, etc, etc .... are not very well written and there are conflicts on the SPI bus (for example the SCK signal which remains high, CS signals which do not not go up, etc ... Read the forums and the excellent video of Sayanee Basu. Without a logic analyzer and a lot of development hours it is impossible to operate 1 SPI master device and only 2 SPI slaves. Not to mention the other connection mode, "daisy-chain". With I2C, I don't never had a similar problem.
We
why different modes are required? Any advantage is there with the indudial modes can you please answer for this?
I think it's for the engineering department. Most of us are just users even as semi-engineers. Each computer module is a computer, so they come to the door, call first or throw the package which is hidden for the usual code or life where we are, level 6 or something. In most cases we just follow the instructions to get it working. We buy "the best module" and that's all, so to speak. The top engineers are in another world, some future plans or something.
bro hats off to you.
Thank you so much for watching!! Please don't forget to subscribe to our channel
Thanks!
Thank you so much for your super thanks!!
Very good
Thank you so much!
can you explain more about the modes
Okay, I'll work on it!
@@FoolishEngineer thanks ❤️
تشکر وهزاران لایک لطفا ویدیوها. را بزبان فارسی ترجمه نمایید ممنونم❤❤❤❤❤❤🙏🙏🙏
Nice video
Thank you so much, Glad you liked it!!
Big fan❤️
Brooo!!!
Are bhai bhai....
Bete bete
Why this Protocols have master slave configuration
There must be only one who can initiate the data transfer,
Also there must be only one device which can control the clock for the communication, if both starts accessing the clock.
Clock line will get currupted by one-zero transitions.
Thank you so much for watching!!
The Modes Listed In This Video Are Incorrect!!! I was just sent on a 6-hour wild goose chase trying to track down why my microcontroller wasn't transmitting in the correct mode based on the timings I measured on my logic analyzer, only to find out the modes listed in this video are incorrect, so it was working correctly the whole time! The video has the CLK Phase incorrect; therefore, Modes 1 and 2 and Modes 3 and 4 are switched!
Very good video but thoking language in speaking hindi please
Thank you for your feedback, I'll check!
can i contact to you sir
