Serial Data Communication Standards...

[Chad1]

What about a video which explains the concept of serial data communication and most of its standards (RS232, RS485, CAN, Ethernet, USB, ...)? This topic never came close to being addressed in school, but it would have helped me greatly in the early stages of my job. I think Dave could provide excellent commentary on this subject that would appeal to "young players." Anyone else agree?

Sounds interesting to me.

Man.. you are talking about entire Polytech course or more stuff there. For example ethernet alone has the hardware specs and requirements, multiple software layers and plenty of official standards.

But It would be interesting to see what he gets out of those.

Ethernet and USB are really more intelligent protocols that you probably won't interface directly with anyway. (But through glue logic.) But RS232, RS485, CAN, SPI, I2C, those are thing that can reasonably scoped, and even bitbanged if one were so inclined. A video series on the simpler communication protocols, touching on both physical stuff (voltage levels etc) and the protocol would be great.

Just a minor Nitpick.. Usb is bitbangable (  ) at the lowest speed. Also many sub2$ chips have full usb 2.0 compatible build in hw, so it's not as far fetched. It's definitely in intermediate category topic, but so is CAN.

I agree with all of you. This topic covers enough material to warrant its own course. But so does a lot of things Dave talks about. I'm saying just cover the basic ideas over a ~40 minute video. Or make it a trilogy of videos to be more thorough. It would certainly be the only one of its kind on the net (trust me, I've scoured it).

I would love to see video like that. I don't want complicated polytechnic stuff. I want Dave's interpretation that is condensed and easy to understand. All the essentials and real life important stuff without everything boring and useless.
