potatohead's Blog - It's a multi-color Propeller!

[RSS Bot]

Had an extra day of hotel room time, so I went ahead and did some exploring of color potential on the Propeller. IMHO, it's not bad at all! Just using the reference video output circuit, I was able to get 400 colors on screen, by over clocking the pixel clock to twice it's normal NTSC running rate. Essentially, it's two pixels into what would otherwise be a single pixel Atari style NTSC color clock.

Initial results were pretty decent. There are plenty more colors possible, given some serious thought to choosing palette choices, etc...

 

This is a 320x96 image, which consumes nearly all the RAM. Looks like I'll likely either need to generate video on the fly, or get the SRAM addon to do more than just plot some dots.

 

One other thing that could be done is interlace this color, so that the effective resolution would be 320x192.
