SPI protocol features and how to integrate multiple sensors // Arduino Zero, LoRa and E-Ink modules

[@davidbristoll195]

This video is really top quality. Very clear and helpful. I love how you dug deep with the theory and showed us the signals. It'd be very helpful if you could talk a little about the reset and DC pins as it seems assumed that each device needs its own pair of those as well as the chip select pin.

[@Alkatross]

Incredible video!!! This is the first time i heard the controller/peripheral language used instead of the deprecated version when describing the spi data lanes. I feel so much better not remembering human suffering every time i destibe my computer program.

[@michaelbishton9439]

Your explanations were clear, but content was not for a beginner, like me. You used terms that sounded to me for the more experienced ear. THANK YOU for your effort.

[@chorty58]

Congratulations for your video: clear explanations, solid knowledge, good "script" as well as modesty in recognizing you had some bugs. Fortunately, this has never happened to me, so that I don't really need such instructive and valuable videos.

[@KinleyPenjor-xt2sh]

Beautifully explained.

[@davinderc]

Came here from Arduino's FB page, great explanation! I'll have to have a closer listen after work.

[@nurardlirachmatsaputra8231]

Thank you very much Sayanee. This video really helps me :)

[@bobdole27]

Short and Informative. Perfect.

[@deserteddrake]

Thank you for this Video, Sayanee! I will use SPI for a Muses 72320 Volume Control Chip for a high end Tube amplifier. So this was very helpful for me! Best rechts, Falk

[@soufathekiller6615]

underrated video

[@krishnawa_]

This video is helpful Thankyou Sayanee :)

[@vamshioruganti6319]

Thanks for this video Sayanee. In this video, I learned about SPI communication. it helped a lot. Thanks for your great work.

[@halalexpressions]

What software do you use there to show wiring connections?

[@alistairmurray626]

Awesome!!!

[@krishnawa_]

Thank you for the information

[@soufathekiller6615]

hey umm do u have a platform you use for chat? i just wanted to ask a few questions if you don't mind

[@lukaszmolawka7590]

It is possible to connect multiple devices with different spiclock ? Br

[@NikiDorian]

Lovely presentation as always! I found the music distracting though.

[@sayanee]

Sorry about that! Thanks for the feedback. Noted.

[@bollie9752]

I skipped your last video (stopped after 30 seconds) because of the volume of the music (was about biographies). Didn’t mentioned it, but yeah maybe a little bit less. I Love your explanations though, so pls continue!

[@sayanee]

@@bollie9752 Thanks! Please do feedback next time as I'm experimenting and learning too! Appreciate your feedback :)

[@davinderc]

@@sayanee the music didn't bother me and I think it's a nice background texture to have, maybe just a slightly lower volume? Honestly I find it to be pleasant background music!

[@sayanee]

@@davinderc Thanks! Yep yep, trying to settle on an appropriate dB level in daVinci Resolve. It was about -20dB. Will try with -30dB music background next time :)

Top notch, your clips are well structured. I was wondering, what is your target audience. 11k views with such a great film is very little. For my experience, a tinkerer and user, your clips are quite advanced. You use over the shelf hardware, that has no isolation optocoupled in/outputs etc, so your emphasis is obviously not the user. Also you do not go the extra step to implement a useful use into your project. Your clip is just an entry to a possible implementation of some component. That does not excite tinkerers, nor users. Ok, left are the pros and maybe one day pros and students. Students will watch your clip only, if they need to to complete their given project. Pros are probably interested in your clips to get started with their project. Anyway they might be near your skill level and they are few. A clip and info with such a quality like yours deserves more. I find clips most promising, when they have a clear useful project in mind. F.e. your Lora communication. Very hard to find a use for such a thing. I was thinking a farmer, whose fields are near his house. He wants to measure earth moisture content via SPI device, have a GPS to find his sensor when its getting winter or he is harvesting the field. And get an alarm when it is moved or stepped on by a cow, so he needs an accelerometer on board. He wants to get an alarm on the cel when its to dry and wants to interface his waterpump with it to automatically water the field. What would be the target audience of such a project. Tinkerers, who can use one or the other part of the script. Users, like farmers, growers, tinkerers, hempgrowers, glashouse owners, universities bio centers and many many more come to my mind. Even pros that look for some functionality. Not many people want to reach your skill level, in fact I never could. But so many people in the world would like to profit from your skills. What do you think? I took the time to write this, because I think you are worth it.

[@sayanee]

Thank you so much for your feedback! Especially about using it in a project. And I totally agree with you. I did eventually use this screen as part of a project here: kzbin.info/www/bejne/b2HdmpytoLR9fNk As projects take time to build, I will usually make a video out of a component that I intent to use in a future project for example, this E-Ink screen.

[@RI40555]

hey what if I want to alternate SPI pins since many boards have multiple pins options for mosi,miso, sck etc.

[@mahlodibogashu5211]

Thank u very nice videko but I wanted to understand if a peripherals datasheet doesn't show the register addresses how will I communicate with it and where does the slave send its data to the arduino where can I access that data. Thanks regards.

[@sayanee]

If you really cannot find the slave address in the datasheet, I suggest you post this question on the part manufacturer's forum or email them directly.

[@haridasc823]

I am facing same kind of issue with SD card reader and ili9341 display with Arduino nano,but I can't find a solution.hope you can help me

[@sayanee]

Do these 2 work fine with Arduino Nano separately? If yes, then I suggest logging the signals for each of them and compare them when they are integrated. The debugging process would be the same as what I did.

[@haridasc823]

@@sayanee yes working separately but display fails one SD calls.

[@Jbrimbelibap]

Oh wow, that guide is very nice but your module prices are just outrageous (8€ and the microcontroller uses usb micro !??) I know why I buy on Ali express

[@benediktpenner7580]

I have used one of these modules with an Arduino Pro Mini 3.3V www.amazon.de/gp/product/B084NWDFH1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and one of these Boards: www.amazon.de/gp/product/B076T28KWG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I had a lot of problems getting them to work... But i have never thought about checking with the logic analyzer. Next time, I will! Thanks for this great video!

[@kellyspoolhall761]

There was nothing wrong with the old pin names. The references made perfect sense. My guess is that some progressive idiot felt triggered and went on a mission.

[@LeoH3L1]

To hell with that woke BS.

[@seanocansey2956]

I guess "Master" and "Slave" didn't age well? 🤔

[@Schlohmotion]

No one cares

[@johneagle4384]

Sorry... but this is all style and very little substance. It did not help at all.

[@scootergirl3662]

You must just have a different goal than her. I learned a ton for my LoRa project. There are other KZbinrs that are definitely all style and little substance. This video isn’t it
