[z80] Problems building an OS
« on: March 12, 2013, 12:52:03 pm »
Hey guys,

Don't misunderstand the title, I'm not planning to code the best OS, nor any OS that has useful stuffs in it at all in fact :P

I just downloaded SirCmpwn's AsmOS and only tried to add this to boot.asm at line 140, following the readme's instructions :

Code: [Select]
bootedLoop:
ld d,44
ld e,28
ld b,8
ld iy,$90D3
ld ix,sprite
call PutSpriteOR
ld iy,$90D3
call BufferToLCD

ld a,$FD
out (1),a
in a,(1)
bit 6,a
call z,ShutDown
jp bootedLoop
sprite:
.db %00111100
.db %01000010
.db %10100101
.db %10000001
.db %10100101
.db %10011001
.db %01000010
.db %00111100

The shutdown code is working fine (I mean that it effectively shuts down when pressing [clear]) but the sprite ...



I didn't change anything else ... do you know why it's not working ?

Thanks by advance :)

I think SirCmpwn can help you on this, you can contact him on EFNet via PM.
