what USB adaptor to get with the 633?


New member
Getting ready to buy a 633 LCD and got 2 questions:
1. what USB adaptor to get, im getting an it7 mobo, and i dont care what model it is, because its gona get ripped apart anyway :)
2. How do the buttions actually work? I understand that it goes from the screen though the serial, and the software interpurts it, but is there any writeup on how to program for the 633?
Thanks Again!

There is no software that uses the buttons on the 633 yet. Supposedly, future version of CC will.
oh i realize this, im asking more for the USB adaptor, I want to write my own software to control the LCD so im questioning exactly what gets send to the serial port when a buttion is pressed

For programming examples, please look at the source code for 633_WinTest:


633_WinTest is a bit complicated, so here is an ultra-simple command line program that communicates with the 633 (including showing keystrokes):


And a Linux port of the same thing:


The data sheet also documents all the commands and responses:

How's the 633 soft. coming?

How is the 633 software coming along? I'm very, very interested in ordering it but I am waiting for the CC program. Keep up the good work. Also, how are the colored serial displays coming? I know a while back ago I asked if you were developing a blue/white scheme and you answered yes. Can't wait to see what you come up with next.
