[Amforth-devel] Adding own code to amforth: reserving heap space

[Christian B. <cas...@ca...>]

Servus, (=bavarian for hello and goodbye)

I am trying to add video-terminal code to amforth, and currently it only kinda 
works.

I can enter text and it gets displayed, but whenever I press the enter key it 
mostly crashes.

I suspect that my software and amforth use the same memory areas.

I am currently using a code like this to allocate space on the heap:

.dseg
.org heap
keyboard_buffer: .byte 1
keyboard_shift: .byte 1
.set heap = heap + 2
.cseg

I am not sure if this is correct, but if it is I will also check if I'm not 
messing with registers in a way I shouldn't.

Hi,

not sure whether this helps: You did look at the application 
in amforth/appl/tv, did you?

Good luck,
Erich

No, but that sounds interresting. What is it and where do I find it? I don't 
have an appl directory.

I found the bug now, insteadt of writing
.set heap=heap+XSize*YSize+...
I wrote
.set heap=XSize+YSize+...

I am now almoust done, BTW. The only thing missing is shift on the keyboard.

You need to look at the svn sources directly:
http://amforth.svn.sourceforge.net/viewvc/amforth/appl/tv/


Cheers,

Ohh I was able to get it from therw. It seems like you did preety much what I 
did. I think from what I have seen the only point where I could claim my code 
to be better is in the vsync area, but that's largely irrelevant. Ohh and my 
clock doesn't need an additional quartz.

Anyhow, are you interrested in getting some FM-Synthesis sound routines for 
your application?

I'm collecting everything and publish all I'm allowed to do.
But the TV application is not mine.

I'm sorry to tell, that the link does not work any more...

The reason is simple: a reorganization of the repository
structure. It is not yet fully finished but I think it won't change
a lot again, since I use the new structure internally for quite some
time. The only thing thats left is around applications that I cannot
work with, like the tv application. The actual link for them is

http://amforth.svn.sourceforge.net/viewvc/amforth/applications/

All new code is now in trunk, regardless of core or library or
(my) applications.
