[A83] Re: CREATEPICT
I deleted the picdata label and replaced that line with ld hl,(gbuf), but it
still saves a glitchery image into pic1. Anyone else got any ideas? Here is
the source after I made that change:
.nolist
#include "ion.inc" ;tells TASM--the compiler--what file to read
from to define rom call memory addresses and such
.list
_CreatePict = 4333h
PICOBJ = 07h
lcdinstport = 10h
lcddataport = 11h
tPic1 = 00h
tVarPict = 60h
#ifdef TI83P ;a check for TASM to see whether it is making an 83
program--if so, do the next two commands
.org progstart-2
.db $BB,$6D
#else ;if it isn't an 83 program, then do something
[#]else--the next line
.org progstart
#endif ;simply ends the #ifdef command
ret
jr nc,begin ;Jumps to the beginning of the program (this
line and the below three will be
.db "Create A Pic",0 ;The title displayed by ION--anything
you want
begin: ;defines where label begin is, program code follows this
label
ld b,8 ;the sprite is 8 high
ld a,0 ;make register equal zero (0)
ld l,a ;now make register l equal (0)
ld ix,sprite ;load the sprite into register ix
call ionPutSprite ;call the library
call IonFastCopy ;copy the graph buffer to the
screen--displays the sprite!
bcall(_zeroop1) ; load var name
ld hl,picname
ld de,op1
ld bc,3
ldir
bcall(_chkfindsym) ; look it up
jp nc,load_data ; skip to loaddata if exists.
bcall(_createpict) ; else create pic
load_data:
inc de ; skip 1st length byte
inc de ; skip 2nd length byte
ld hl,(gbuf) ; pic data
ld bc,756 ; pic size
ldir ; copy data
ret
picname:
; Recall our tokens class...?
.db picobj,tvarpict,tpic1
