Sorry, but this was written for coders, Normal people may not understand

NOT FOR REGULAR 83+s, IT WILL CRASH!!!


Heres some work I did on greyscale
I used the The 83+se crystal timers to draw at ~62Hz
Thats for both the 4 level and 8 level grey(seems to be the best)
Keep in mind the screens are drawn in the interrupts so
some code can occur, especial if the cpu speed is set to 15MHz.
Do Not view under fluorescentlight


Just so you know I wrote all of the greyscale routines, 4 or so exist
Each running at ~62hz

-Fullscreen: ~24,000 clocks
Uses Lcd speed set at $a7, and only update 2/3 of the time compared to rigwiew

-Byte Interlace: ~60,000 clocks
Based on RigView, Lcd Speed set to $37, updates every Interrupt

-8Level byte intelaced: ~13,000 clocks This requres a routine to be called to reorder(data written top to bottom left to right)
and interlace all seven buffers, it "outi" 64 times and set lcd speed at $d8 No delay required

-8Level bit intelaced: ~13,000 clocks
> This requres a routine to be called to reorder(data written top to bottom left to right)
and interlace all seven buffers, it "outi" 64 times and set lcd speed at $d8 basicly the same.

Usage
Every thing is pretuned to my SE, but yours might not be the same.
Must hold "ON" to tune, tap keys
Fine Tuning
Divide = decrease
Multiply = increase
Tuning
Minus = decrease
Plus = Increase

An 18 second video of Gohan from DBZ, GIF runing fast and i'm to lazy to fix
4 levels of grey, uses rigview style noticeable noise, on pauses
160 KB app, 10 pages, 10 frames on each data page, total of 180 different 768 byte pics
mov.8xk = Interlaced by byte (RIGVIEW style)




cute
My sister 21 years ago...ahhh
8 levels of grey, rolling does occur(you'll see what I mean)
tuning may lock up the calc hold "ON" and press "^" to set to ~54hz
AGREY8I.8xp = Interlaced by byte (RIGVIEW style)
AGREY8IB.8xp = Interlaced by bit (Greyscale Development Sytle)



speed may vary
Raycaster browered from Maze-3D v0.5 Beta By Clement Vasseur
4 levels of grey, no future development is really planned
The Fullscreen draw version waste MUCH less clocks than RIGVIEW, Mild flicker
AMLIBI.8xp = Interlaced by byte (RIGVIEW style)
AMLIBF.8xp = Fullscreen draw (Old school)



this screen shot isn't that great
Old Mapper of mine I dug up, Tiles where hand drawn, Before GBTile extracter came about
4 levels of grey, Fast scolling seeing how 3 halts ocuur per frame to SLOW things down
Might not be fast enough for a mario game but who knows.
If speed Is needed the fullscreen routine might be able to provide it
APOKE.8xp = Interlaced by byte (RIGVIEW style)
