The PorpGFX drives the AD724 through R2R ladders in analogue 15Bit RGB video.

IO Classifications

15 for RGB
1 for Composite Sync
1 for AD724 Clock Generation
1 for AD724 PAL/NTSC Switch
2 for Data Bus control
8 for Data Bus
2 for EEprom
2 for PropPlug

Just one cog is used to produce the display!

1 Cog produces display timing and sends rgb values to AD724.
1 Cog handles IO
the last 6 Cogs for rendering the background and sprites.

Thanks guys.

With that solution, overlay is best done in software, bit mashing with the remaining COGs.  Very cool.  When Prop V2 hits, that engine is gonna scale nicely.  

Yeah, can't wait for PropV2, that's gonna do some serious graphics And some decent emulations too

It'll do some decent everything!!
Look what we're able to do with only 32k. Now picture 8 times that!

Quoted from Baggers

Yeah, I've been thinking of modding the basic, to allow andrew's music, and propgfx, so it'll have sprites etc too
I believe coley wants to reply to the other part

When you go about doing that, let me know.
I'll help work out the sound support.
Thanks!

Ok Andrew, no worries, we'll be onto you for sound support

And your right about what we've done in 32K, then prop2 with 8* the memory and 8* the speed per cog, and 2* the cog count, it's gonna kick a**.

I've now made a BMP/DDS viewer, which scans SD for files, and then shows them, you can use joypad or keybaord to do next/previous image BMP's can be 8,16,24 or 32bit, and almost any size, as it resizes BMP's to 128/96 15bit as it loads it. DDS's have to be 256x256 ( only shows 256x192 ) as I don't want to resize that, and re-encode to DDS. big files redraw slowly, but SD transfer is only about 300KB/s, it happily loads a 17MByte image, 2832x2128 24bit, albeit slowly, but it will be faster when I or Rokicki adds a file seek function to the SD routines.

I'll also hopefully be adding JPG files access to the viewer too, so it can load/resize those too.

If ya want I'll post some pics, or movie of it in action? let me know which.

Gotta be a movie please Baggers!

Here ya go, here's a pic and youtube of the Hybrid+PropGFX BMP & DDS Viewer, which scans the SD for files, and then loads the first BMP or DDS it comes across, then you press left or right on joypad and/or keyboard to cycle backward and forward through the images, automaticall scaling BMP's to fit on screen

Enjoy

Hi Baggers!

Nice demo  

Will this work as an automatic slide show viewer or do you have to select the pictures with the joystick?

Regards,

Coley

Can make it an automatic slide show on button press good idea thx.
