Understanding SPI

[@selvakumarr6672]

Crisp and clear. Covered basics very clearly. Thanks.

[@pauldenisowski]

Thanks! I have another video on serial protocols that should come out in the next week or so :)

[@akshaynk130]

perfect explaination, especially about CPOL, CPHA, and sampling etc

[@pauldenisowski]

Thank you!

[@JaymzBond]

Thank you for this short and concise tutorial

[@shahdmahmoud4214]

This exceptionally simple and very detailed

[@pauldenisowski]

Thank you!

[@sushanttodkar8294]

Thanks for very clear and easy explanation for SPI.

[@pauldenisowski]

Thanks!

[@amrrasslan4329]

crystal clear .would love to see CAN and LIN protocol .

[@pauldenisowski]

Thanks! I actually am already working on LIN and CAN (plus CAN-FD and CAN-XL presentations) but they probably won't come out until sometime next year.

[@JeremyCook]

Nicely explained. Thanks for using clear terminology (MISO, MOSI).

[@pauldenisowski]

Thanks. It's the same terminology that we use in our oscilloscopes :)

[@deepakchikne6751]

Simple and Clear.

[@pauldenisowski]

Thanks!

[@santoshsco]

Crisp and excellent !!

[@pauldenisowski]

Thanks!

[@beliveinjesusglory1326]

Very good presentation 👌👏👍

[@pauldenisowski]

Thanks!

@Rohe Schwarz, In case of Daisy Chain, How Slave1 knows that data has to be transferred to Slave2?
Is it based on Clock from Master with no-data(SDA is neither 0 or 1 level voltage)?

[@sp-wk7do]

Make a video extended for this,for XSPI protocol, thanks

[@tuphanxuananh]

Great explanation of SPI!

[@pauldenisowski]

Cám ơn rất nhiều!

[@tanmaygote7330]

will you please make video on CAN Protocol

[@jeffreyzhuang4395]

You explain it so WELL!

[@omerfarukkara4138]

Amazing clarity.

[@philippelhaus]

Great content❤

[@ВалерийМандругин]

At last! Nice and simple explanation of SPI)

[@pauldenisowski]

Thanks! I've also done videos on UART and I2C, and I have a few other serial protocol videos under development right now :)

[@EMAGK]

​@@pauldenisowskican you explain I3C

[@pauldenisowski]

@@EMAGK It's on my list :)

[@AAAAAA-ny4ib]

Hello! I send a data packet "slave func data srs16", but the result is this signal "00 slave func data srs16". Why do two zeros appear? ModbusRTU

[@pauldenisowski]

Sorry, but I'd have to know a lot more about the implementation to try to answer that question. Are you observing the packets using an oscilloscope or logic anaylzer?

[@bramlemmens6984]

thank you so much for this!!

[@pauldenisowski]

Thanks for the feedback!

[@mahadesharya6975]

Excellent!! Thanks very much

[@pauldenisowski]

Thanks!

[@bendibhafed1687]

Amazing video,

[@pauldenisowski]

Thank you!

[@technical5880]

you made it eazy.

[@rd-tk6js]

excellent, thanks !

[@mortezapanah8762]

Great help

[@Adrian-nq2bp]

Awesome, thanks

[@ថាន្នីសុគុណ]

that great vdo.

[@krishnap9116]

Thank you so much..

[@pauldenisowski]

Really appreciate the support!

[@sahanpweragoda]

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.

[@architjoshi2199]

At 8:34 should it be CPHA = 0?

[@pauldenisowski]

CPHA = 1 means "read on the second (trailing) edge of the clock pulse". Since CPOL = 1 (idle high), the clock pulse is negative or inverted, so to speak, and thus in this example we're reading on the trailing edge of the pulse. The "CPOL/CPHA" terminology is very confusing -- even device manufacturers sometimes get things mixed up in their literature.

[@architjoshi2199]

@@pauldenisowski Thanks for responding. I found contrary on the Analog Devices page (I wanted to put link here but UA-cam is ridiculously removing my comment with URL)

[@pauldenisowski]

@@architjoshi2199 Yeah, I saw the Analog page too. In fairness (and as someone who makes about a thousand slides of content a year), it's impossible to avoid making mistakes every now and then :)
