USB Protocol documentation

Open francisdb opened this issue 4 months ago • 3 comments

I'm trying to write a ZeDMD driver but having a hard time connecting to the device. Is there some documenting on the protocol? Mainly looking for the handshake and framing setup. I tried reading the code to no avail.

The C++ code is here https://github.com/PPUC/libzedmd/blob/4691e0c2ea9d9c9491a5461618e55c1dee98d8b3/src/ZeDMDComm.cpp#L426

@francisdb the protocol is not guaranteed to be kept stable. What is the issue with using libzedmd?

There is no issue. Just wanted to try writing my own driver.
