EEVacademy #3 - Bit Banging & SPI Tutorial

What is Bit Banging and how to bit bang a SPI bus.
Also how to use an Excel spreadsheet to do logic simulation.

Good stuff, like the shot at the end too..

[SIMPhony]

Thanks! This video taught me bit-banging in less than 20 minutes, which is absolutely fantastic. Yes, it requires knowledge of digital signals and gate logic.... but Dave already explained those in separate videos previously, so I don't see the problem many seem to have with this video. I think it's good you don't spend extra 40 minutes explaining all the basic concepts.

I think these videos are great for an intermediate / advanced electronics enthusiasts / professionals like myself. No wasted time on things I already know, clear and to the point. Thanks Daves!

[andyburns]

depends on the clock speed, not necessary to do polling and eat up all your cpu time, I've done interrupt-driven bit banged spi slave on an esp8266 (yes my beard is grey)

[MaxJ]

Great video. Very clear and concise. The pace kept me interested the entire time, without being too fast.

[musmodtos]

Perfect, for us who use the theory but aren't so as up to speed with the hardware you've pitched this just right!

Thank you!

[SzDavidHUN]

Best spent 18 minutes in a long time. A little bit fast, but useful, clear, simple. Thanks Dave!

[MAYOJAMESD]

i give him a 10 for clarity and explaining, but a 1 for use of hilarious australian expressions. we were never in like flynn and bob was never my uncle. this channel should be 5% learning, 94% bloody ripper, and 1% release of magic smoke

[RRak]

Co-hosting EEVBlog like that is the best idea since the channel started :)

[Unknownety]

Really nice, this type of segment turned out better then I expected.

[RiyadhElalami]

Very well done, he is fast which I like, and he has a clear voice and nice explanations 8/10

[vovetsno]

Very nice start, Dave! Keep it that way. Fast and clean (as was previously said).

[timkent]

Great video! I like the fast pace too, no stuffing around!

[XeonXR]

Honestly one of the most clear and concise tutorials I've seen in a long time! Well done Dave2 - keep-em up! Would love to seem some RS485 demonstrations using a Teensy 3.2 or something.

[Mriks]

Hi Dave nice to see you again :) good tutorial and hope to see more videos like this in the future

[shinyshadow]

I think its a good explaination of SPI, tought me a thing or two, and it seems I'm always bit-banging.. grrrr Nice one Dave 2

[TKomoski]

Like the visible colors David, cool tutorial on progian code ...

[Gossamer]

Thanks David! I have played a little with the Dallas 1-Wire stuff which was kind of neat, and I've wanted to know more about SPI and other protocols. Here's a suggestion for a future episode; how to JTAG any device and read/write the chip contents. We know you're the hacker type. :)

[bitrot]

Great job, Dave2! Can't wait to see what happens when you hit your groove after a few more videos. Keep it up!

[NorbertHarrer]

Excellent Video. I loved it. Haha. The head swap at the end. That was the money shot :-D
