.... for PropBasic: Interface to TV 40*30 and to Keyboard; Mandelbrot Fractal

Christof Eb.

Hi,
perhaps this is some use to someone:
PB_TV_Key.pbas is a demo in PropBasic how to interface to the existing drivers TV half height, and Keyboard. It works with the demo board pin setup.
Minimal changements in the driver files to get the adresses of the buffers.

Have fun.
Christof

Hi Christof,

Thanks for posting this demo!

I like the Spin despatcher and am studying the LMM.

Hi,

·just something to play with:

a Mandelbrot fractal generator, works with demo board and ntsc. Something like a mathematical marvel....

Ofcourse this can be modified: parallel processing for speed.

You can play with xmin, xmax, ymin, ymax

Ideas, comments?

Have fun,

Christof

P.S. There is some flickering on my screen. I could not get rid of it, I wonder if this is an issue of my tv-monitor.

The fractal is very cool.
May I include it in the demos program for PropBasic ?

P.S. It is stable on my display...

Use BASIC on the Propeller with the speed of assembly language.

Hi, this is an update of the fractal generator.
The program now searches for the most interesting part·of the screen and enlarges this part.
- Something like a screensaver for sphinx??

The flicker of the screen on my monitor is no more there, after I reduced the vertical sync to only one line. Had been 4 lines. (Line 330 of the source)

Have fun, Christof

Yes, Bean if you want to, you can include this into your demos. Still stable on your screen?

Christof,
Yes, it works fine on my monitor. Very nice.
