Add Support for Z Machines #9

Open hotzenklotz opened 4 years ago

hotzenklotz commented 4 years ago

Right now, the picobrew-server only supports the Zymatic machine protocol. It would be cool to support newer machines from the Z family as well.

@bendavis @blucey Perhaps you could share your MITM captures here.

Here is a firmware file for the Z zseries_0_0_116.bin.zip (provided by @Blackjackbuyer)

Perhaps, we can figure out more of the protocol by looking at the strings in the firmware:

@blucey did a great writeup of the Z protocol so far. I added a few modifications, but I think we're on our way to mapping this thing out. https://github.com/blucey/picobrew-z-api/blob/master/Picobrew%20Z%20API.md
