Phillipp,
I'm the loon that
Phillip,
My primary interest is in the 'bog' standard Z80 and the Z180
(HD64180/HD647180).
I am also intrigued by the possibilities of the T80 but haven't gotten
there yet.

Kevin,
My best guess is that your local variable definitions are VERY wrong - you
might want to try:
void putchar( char ch )
{
unsinged char *pScreen;
unsinged char *pX;
unsinged char *pY;
char x;
char y;
pScreen = (unsigned char *)video;
pX
ocument those techniques that are working for us The
collection/collation of results such as these should represent a valuable
reference for all SDCC users.

that the addressable
(static) data be in the same logical address space as the code; but I
don't
know really.
I must confess, I don't really understand what I've done; but it does
work.
I would be happy to have any further light shed upon this...?

Richard,
Glad to hear that you solved your problem.
I was literally composing a response for you when your message arrived a
few minutes ago - good timing. (I'm no expert but no one else seemed to
be jumping in so I was going to have a go based on faded memories of a
much earlier project :->)
C
use Windows here.
I don't suppose it would run under X/WINE ?? (Linux IS a wonderful thing
- most of the time :->)

Guys,
On the general topic of Z80 development/support:
Is anyone out there targeting the eZ80 with SDCC ?

particular interest was in the HD647180 - the embedded
microcontroller version of the HD64180/Z180. He spoke at the time of
doing a Z180 specific port of SDCC. He may have some help to offer...

will likely take a LONG time...
So, it certainly aint dead as far as I'm concerned.

(I am happy to be corrected), the SDCC builds are
limited to the normal Z80 64K linear address space. This is not to say
that you cannot implement your own methods to make it work for you - it
will simply take more work.
