What's that like on the battery, though. >This is more affordable than expensive piezoelectro mechanical display. The Piezzo electric crystal approach may be more expensive per dot, but it only draws on the battery whenever a dot's position needs to be changed. After that, the dot's position is maintained by a charged capacitor which only needs to be replenished every once in a long while. So, although the hardware cost is greater, the battery cost is lower. It's an interesting trade-off so I'm curious. >After having a glance at the code, I couldn't figure out what is the protocol >to be followed to communicate with BRLTTY, how to send key inputs and receive >data. Also what drivers to use. Brltty doesn't have a specific protocol. If you've looked at the code then you know that it has a lot of drivers. That's because, for the most part, each braille device manufacturer uses its own protocol. And, in case you're going to ask, no, I don't think there's such a thing as the best protocol. Each one has typically been designed to support the kinds of controls that it's manufacturer is using. -- I believe the Bible to be the very Word of God: http://Mielke.cc/bible/ Dave Mielke | 2213 Fox Crescent | WebHome: http://Mielke.cc/ EMail: [email protected] | Ottawa, Ontario | Twitter: @Dave_Mielke Phone: +1 613 726 0014 | Canada K2A 1H7 | _______________________________________________ This message was sent via the BRLTTY mailing list.
