help learning asm, needed ?? - Page 3

On the A500 you could attach something to the expansion port that replaced the entire CPU with an emulated one, with full debug capability. Like an Action Replay it could see all the custom registers and anything written to RAM as well.

Well, really just an Action Replay with a USB or serial port would be enough. I wonder how feasible it is.

Thanks for the link

.

A cool reading that allowed me to begin to fill some of the holes that others reading began to dig/raise in my 68k learning process

I love the WinUAE debugger, but source level debugging would be the bee's knees.

What's diference between the actual debugger and a source level debugger ??
one debug from the memory and the other from the source code ??
Is there a doc about the winuae debugger ??
Sorry for noob question and since i made this thread

i didn't have the time to have a look about it.
But i hope i'll have very soon.

By the way thank you guys !!!

More coders the amiga will have more the scene will be alive !!!
long live to the amiga !

A basic debugger just disassembles the machine code and shows you that. So you don't get the comments and the formatting from your source code, and sometimes the disassembly is wrong too (e.g. it mistakes data for code).

With a source level debugger you can step through lines in your source code so it's much easier to see what is happening and fix problems.

While searching for something else, found this article @turrican3.
I you want to read it...

Are all of the Amiga Format magazines available online?

Does anyone know where... I have big respect for Dave Jones and I'd love to read that series.

All, I don't know. But some can be found : http://eab.abime.net/showthread.php?...79#post1334479

All seven issues of Amiga Format featuring Dave Jones' series is in the zone now.

Nice one!

roondar · 20 August 2019, 16:38

Note that these are all also on archive.org for those who want a more 'permanent' source. But still nice to see them in the Zone

malko · 20 August 2019, 21:51

Happy that this reading I pointed to was also useful for others and not only for turrican 3

Thanks for putting it in the zone LongLifeA1200.

Now hope that turrican3 had a look at it

How does one go about getting access to The Zone to read these articles? The link above says that I am trying to access a restricted area?

I know this is an old post but maybe people still return here for guidance.

I was trying to learn Amiga ASM for 7 years, but was not until I read like 100 pages (several times) of the PDFs "Amiga_Hardware_Reference_Manual_3rd_edition" and "COMPUTEs_Amiga_Machine_Language_Programming_Guide" and "Amiga_Machine_Language_Abacus", that I finally started to get enough fundamentals to do some simple demo coding.

You slowly start to see the logic, that ASM is all about moving data around inside the $MEMORY, using the CPU for simple logic, math calculations and COMPARE A with B...THEN JUMP to Subroutine, and of course using the specially assigned $CUSTOM_CHIP_MEMORY functions like $dff180 = background color.

Reading other people's code is simply insane

Anyway, good luck to anyone getting started, it is totally possible, but takes a little reading and testing. PS. I use AsmPro from Aminet, in hires 4 colors, works great.

Not the same books but quite the same conclusion here

jel's (FR) [ Show youtube player ] & Photon's (UK) [ Show youtube player ] video tutorials (watched again and again

) were of great help as well.

the best is to try to copy / code simple examples from books and see them in action / step by step debug

also learn about hardware registers/copperlists and basic library startup/end (graphics/copper).

- If you need to allocate memory you need exec AllocMem / FreeMem
- If you need files you need to open dos.library and learn Open/Read/Close...

There were pretty good books at the time. I used basic "Micro Application" asm book, and also the Amiga Bible...

Copying / typing source code from paper to computer was also part of the learning process. Copy/paste teaches nothing.
