Hello
I'm a Computer engineering student in a university. I and several of my companions must do a project for the class of microprocessors.
Basically, we must do a Sudoku for the propeller, so that it could see in a television or on a screen of computer and play with it.
In my university we have some "Starter Kit" like this: Starter Kit
The problem is that we don't know how use the objects like "TV.Spin" and " Graphics.Spin" of the propeller development program library. Therefore we can neither draw things on screen, nor draw text, nor something like this.
There is some manual about this?
Thanks

    The Propeller Tool has two folders of sample programs. One contains the various drivers like TV.spin and Graphics.spin. The other contains sample or demo programs that illustrate their use. There are also useful objects in the Propeller Object Exchange on the Parallax website. Look through the list of what's available. There's no manual yet although there are a few tutorials (like the Propeller Education Kit tutorials). For your project, the best way to start is probably with the demo program for Graphics.spin. Also, you need to read the comments in the various "library" routines like Graphics.spin. Often the comments describe how to use the object.

    Oh, and check out my Video Blackjack game here:

    This is an example of how you can make something that works both for TV and VGA...

    I wouldn't recommend starting from Graphics.spin because the overhead required leaves very little room left for actual game code...

    Rather, I would create custom characters and/or use the ROM font to generate the display. You don't really need to double-buffer a slow game like Sudoku...

    Coincidentally, I have a theory that there is but one Sudoku solution that can be made into any other solution via character exchange and row and column interchange and rotation (has to be done in groups of 3)...

    If this is true, then you can implement many puzzles with just one stored in memory....

    Hmmm, good point Rayman on not starting from Graphics.spin. Students did run into plenty of memory issues. But on the flip side, sure made them deal with those memory issues as a challenge to overcome!

    Graphics.spin does not need double buffering. It's the Graphics_Demo that install this 2 buffers for flicker free Animation.
    With only 1 Graphic buffer you get 12kByte more space for the application, and that's enough memory for a Sudoku.

    Edit: Make the following changes in the Graphics_Starter.spin:
    Change:
  _stack = ($3000 + $3000 + 100) >> 2   'accomodate display memory and stack
to:
  _stack = ($3000 + 100) >> 2   'accomodate display memory and stack

Change:
  bitmap_base = $2000
  display_base = $5000
to:
  bitmap_base = $5000
  display_base = $5000

Delete:
    gr.copy(display_base)   ' copy bitmap to display before displaying

    I think that is a good job, but I haven't got much idea about the SPIN programing lenguaje, so it is quite dificult to understand for me. but thanks in any way

    Yes, I know, I was looking for examples and I did look them. But I can't understand the source code of Graphics_palette.spin and Graphics_demo.spin

    This Is incredible, I am impressed, it is really a magnificent work. The code seems to me to be a bit complex of understanding, but it is incredible that something like that could work in the propeller. thank you

    Thanks, this is an very easy source code, I read it, and I could understand it.
    I think that your students are lucky for have a teacher as you tongue.gif

    I'm using·your library, and I have a question for you. Can you explain me how can I put a digit in the middle of a cell?. thanks
