For my First ASM Prog

BippyM · 01 February 2006, 18:29

For my first ever asm prog I'm going to attempt to open a screen and have a nice copper on it

Can anyone give me some basic advice on starting this? what do I need to consider etc.. should I just poke the regs or do it the system way?

maybe this is helpful...

just change the copperlist to your choice...

I put a copperlist source for you in the zone. I coded it in Asmone and you need Kickstart 1.3 . Try it !!!

ENDE DER KOMMUNIKATION (c) Tron :P

...anyways good luck bippym, hope to see something nice from you soon!

Galahad/FLT · 02 February 2006, 01:03

And on another note, when you assemble that little lot, the copperlist MUST be in chip ram or nothing will be displayed.

Program code, music replayer, music note data can all be run in fast ram, copperlists, pictures and sampledata MUST be in chipram.

Is ASM really hard to learn, i was thinking of trying it myself? I mean all the offsets and stuff look hard to understand but i think ill work it out

Galahad you must be one of the most looked up to people on this forum, i really admire you because of the fact that you were in fairlight (awesome group) and that you can code asm, and track mods if im right

as for bippym good luck on your first prog

BippyM · 02 February 2006, 16:32

I find it hard just remembering everything.

How to assemble gthe actual program (structure) and what offsets are required. Which registers are to be poked with what info etc..

That is what I find hard.

I can read and follow asm to a certain degree.

Joe Maroni · 02 February 2006, 18:06

i think it would be better to start with no visual stuff...

its the hardest thing you can start without any knowledge...
a nice thing i remember was to write the current v-blank position to the backgroundcolor register every cycle...

the result is a screen with more than 32 colors...

i´ll try to find the source of this thing...

coze · 03 February 2006, 16:59

hello x_to,
I just tried to compile your code above but it says illegal operator for the first move.w command. I'm running asmpro (1.16), under winuae with a1200/ks3.0 configuration. where could be the problem ?
hello, btw, this is my first post here. as you can guess, I'm pretty new to asm.

NOB · 03 February 2006, 19:32

Code:

 
s:
		 move.w #$4000,$dff09a ;disable Interrupts;
		 move #$0020,$dff096 ;disable Sprites 
		 move.l #copperl,$dff084 ;activate Copperlist 
..........
.....

press the TAB key to format the asm-source.

Joe Maroni · 03 February 2006, 23:24

yes thats the problem of the EAB editor...it delete TABs..

otherwise it works fine

Ray Norrish · 07 February 2006, 01:03

If you like, I released an intro as a tutorial with extremely heavy comments. Let me know and I will send it to you as I still have it all

Galahad/FLT · 07 February 2006, 01:14

Ray, I still have your source that correctly shuts down the system that you gave me at the Digital party! I think you used it for Sonic Attack

Ray Norrish · 07 February 2006, 01:41

You know, that code was probably the only true sysdown() sysup() around at the time that worked on every amiga/kick.
Might be worth posting

I hand a good hand with that from Randy/Comax for the a4000 compliance. Yes, it was in SA

Alter · 07 February 2006, 07:31

Hi there Galahad/ray I would really appreciate it if one of you would post that code. I been looking for a startup code like that.....for some time now... :-)

I'm interested in it too! Please UL to the zone if you have useful sources (for educational purposes

Yes, release that intro it is interesting to read commented sources.But make sure it will run on my A500.

I`ve uploaded the System close / restore code into the zone. This works for all processors.

Ray Norrish · 08 February 2006, 23:15

I found the intro source, but not the extra commented version I made for tutorials. I`ll upload the code anyway.
