HP50 Grayscale programming (Updated)

[manjo]

Hi :-)

-the idea is to make PICT (your framebuffer) big enough to fit the grayscale buffer
-then setup the ARM LCD controller to use the PICT as framebuffer
-there are a couple of tricks and things to take care when doing this
-ofcourse OPENFIRE does all this for you and more

as far as I know almost all HP50G users put OPENFIRE in their calcs to be able to browse GRO4 and GRO2 images so...
at this point it's not a big deal if you expect/require Openfire to be installed.

Install openfire to Flash (there is a lot of space) it's location is not critical for gamespeed, but the location of the game itself runs fastest in port0, somewat slower in port1 and slowest from flash.

If I had enough time I would go for a adventure engine in port0 with TONS of levels graphics even sound in SD card. Loaded on demand.

best regards,
