Prop1 and PCIE x1 Interface?

AwesomeCronk

Just an offhand thought, but could a prop device be built to plug into a PCIE x1 slot on the host PC's motherboard? How would you write the Windows/Linux drivers to interface with it?

I was going to say "no way," but then I checked the pinout. It has SMBus pins. SMBus is I2C with a few restrictions.


And PCIE provides 3.3v power.


Another option would be PCIE->USB and USB->serial. Or maybe there's a chip that does PCIE->serial. or parallel.

There is at least one indeed; two serial links, up-to 16 Mbps each, and also other features too.

Hope it helps

P.S. Even better options/performance, from the same manufacturer:

I think high-speed solutions while interesting would be way beyond the OPs ability, especially considering that he is wanting answers (solutions) for every aspect. I like the SMBus idea though, nice and simple and no special driver required.

So, PCIE chips, plus prop equals PCIE interface.
All right!

Now, about drivers. How would I make a driver that talks to the prop via PCIE?

One could make a project with this that programs propellers! “Program your prop with PCIE x1!”

I was thinking this sounded cool up until this point. Why would anyone want that specific idea? Seems more difficult than USB, by far.

I could see this for something like a desktop oscilloscope though. Something like a cheap alternative to this guy: https://www.wuntronic.de/en/16-bit-digitizer-4-channel-1-gss-with-4-gs-memory.html

Just an idea, David...

But that O-scope is FREAKING AWESOME!!
