!!!OLD!!! Documentation of hi-speed devices

**T_larson911** · 10-21-2009

I have a question.
When i am printing data on the screen, i want my screen to scroll because i have data coming up and if goes off the screen and i cant see the other data. How do i make it scroll when the LINE variable goes over 17?
I want my screen to be like a Command Prompt where when the cmd prints more stuff, it scrolls.
I dont want to have to type in cls on my computer everytime, i just want the lines to scroll.

Will the wire eyepod/laser pointer ever support hi-speed links? I'd love to make a mouse without using data ports.

What would be the point? Those would only update every tick anyway, so there'd be no speed increase.

Also, the digital screen documentation is wrong.

It uses a whole megabyte of address space (if fully mapped).
Address 1048575 is Clk, not 2047.
Address 1048574 is Clear Screen, not 2041.
Address 1048573 is Width.
Address 1048572 is Height.
Address 1048571 is Clear Column, not 2040.
Address 1048570 is Clear Row, not 2039.
Address 1048569 is Color Mode. Explained below.

Possible Color Modes are:
Mode 0 (default - grayscale): Each pixel is in RGBXXX. R, G and B are from 0 to 9 each, and get multiplied by 28 then added to XXX to get a value between 0 and 999 inclusive (probably clamped to 0..999). Limited colour is possible with this method.
Mode 1 (separate RGB): Each pixel occupies three consecutive addresses - first R, then G, then B. Each is from 0 to 999 inclusive (I think?)
Mode 2 (24-bit colour): Each pixel occupies one address, which contains (65536*R)+(256*G)+B. R, G and B are from 0 to 255 inclusive. Note to Black Phoenix (if he made the digital screen, otherwise whoever did): Mode 2 colours don't seem to be scaled up to the 0-999 range, so either colours cannot be above 25% brightness in this mode, or most of the 0-999 range is unused. Either way this mode seems broken.
Mode 3 (9-digit colour): Each pixel occupies one address, which contains (1000000*R)+(1000*G)+B. R, G and B are from 0 to 999 inclusive.

Also, I can't get Clear Row/Clear Column to work.

Look at the date on this thread...
The documentation is for the old digital screen, 32x32 resolution.
