Galandros · Posted: Thu Jun 24, 2010 8:53 am Post subject: Extra documentation

I wrote a little text file with some things of SPASM that some of you may not know. It is a good supplement to the incomplete documentation.
Download the attachment.

I specially liked to do the macros techniques sections. I found most things on the Revsoft spasm forum.

You can find the normal documentation to spasm in these pages:
http://svn.revsoft.org/spasm/docs/
http://wabbit.codeplex.com/documentation

Please, leave any corrections or suggestions. I will update them until Spencer writes a complete documentation...
EDIT: update with things I forgot to write before!
EDIT2: more things after seeing SPASM source code ^^

Galandros, you are awesome. I will admit I get easily distracted, since as soon as something works I just start using it!

Seek sets the program counter to a specific location. It allows you to re-order code or tables on the fly, but it can be dangerous. You would typically reserve space in the output file with .block, then .seek to each location in the table, and finally .seek to the end of the reserved space.

I'm glad you are looking at the source, you are welcome to make any improvements or changes you like. Paste the code or submit a patch and I will try it out.

probably an answer to this somewhere, but how do I include bitmaps? #include "foo.bmp"?

What should the input bmp file look like in terms of colors if I want to generate a mask? And how are the outputs formatted (ie entire row of sprite, then go down; or entire column or sprite and go left)?

And is there a way I could just echo the output to a file and edit it myself later?

Thanks!

Yes #include file.bmp is correct.

You can specify a mask color with .option bm_msk_rgb=RGB(r, g, b). The default mask is RGB(0, 255, 0). The bitmap is output left-to-right, top-to-bottom, padded to full bytes. Here are the details for bitmap options: http://docs.revsoft.org/spasmoptions.htm

What do you mean by output to a file?

Can I get sprite data (like calcgs or istudio) using a combination of these macros and echo? If so how?

Sprite data? Like the .db statements? You shouldn't ever have to deal with that again. Just draw your bitmaps and include them into your map editor and calc program.

oh and quick reminder, what are the restrictions for apps to be compatible with Nspire's 84+ emu? I'm guessing no undocumented/unofficial instructions (sll or whatever it is). Anything else concerning ROM layout and extra RAm pages?

Edit: and is there a way to check version number of SPASM? I never know if I have the latest stable or not lol
