[GreenKeys] USB/TTY Board Documentation

Mon Sep 16 13:07:43 EDT 2019

Thanks - I do have Mike's adapter and it works well for computer communications. I am still interested in getting the Volpe board to work in a similar scenario.

One of the things which interested me in the Volpe board is the USB interface. Also the programmability.

I just want to expand my toolkit/knowledge so thought it would be a good project to figure out how to use the Volpe board for a 33/computer connection.

At this point what I'm thinking is somehow connect the Volpe board TTY side in the same way the Mike Douglas adapter TTY side connects. I have to fill in that gap somehow.

Eventually I'll fill all that in and add even more pages. If there's anything anyone would like to contribute in the future-- from photos to videos to how-to articles or anything else-- I'd be glad to publish it credited to you. Heaven knows I'm a mere amateur compared to most of the people on this list, so I will only be able to share the few things I learn here and there or just link to other sites.
