Introduce yourself

Hi, again !

It's been YEARS !

Glad my account is still up !

None of you will probably remember me, (hi legolas ! *waves*)
i was a guy asking stupid questions about FPC4NDS and helping out a bit with the code,
for noticing on which processor (ARM7/ARM9) code was running,
but noticed it got changed ... good work guys !

(*crys because he's not mentioned anymore* ^^)

So ... i'm back for a bit ... left pretty fast ... because that's what i do when my work is done.

I've implemented a pretty fast mandelbrot zoom using dynamic code generation on the NDS
and a basic c64 emulator which ran until the cursor prompted ... and then i dropped it because
i acchieved what i wanted. Yeah, that's my way ... there's no profit from that, i'm just doing stuff for fun.

And now i'm back ... looking again for coding pascal on ARM ... but this time, for Android / Archos Generation 8 !

I'll start a thread about this soon because ... i am overwhelmed and don't have a clue ...
and maybe can even contribute some useless stuff about multitouch on resistive touchscreens.

(:

(answers are appreciated, i really need to get into this

Edit: How do i turn off graphical smiles ? i hate them, i'm oldschool ! xD

Hello there! Of course I remember you and your clever questions

I had to remove your hack because it generated some errors. I replaced it with a routine that returned the cpu type by checking for some labels in the prt0. IIRC that function is not required anymore (but don't cry: your name is carved in the stone of the svn repository

)

That's amazing! Maybe you could try to rebuild with a newer fpc version (in the meanwhile the nds compiler and rtl have made a big jump ahead) or even to release the sources...

We can talk about the source of the emulator. Tbh, the mandelzoom was quick enough, but highly unprecise. Couldn't zoom in very far,
but didn't want to put the time into raising precision, because first, it wasn't that easy to implement and second ...
... i had to implement it in the code generator too ... no thx. ^^

I'll have to see where my NDS is', though ................. *lol*

Recompiling the source ... well, i hope it still works. xD I barely used the RTL though, so i believe there won't be issues.

Wow, i just tried to check for prt0 (can't remember) ... NDS homebrew scene grew a bit since then ...

Btw ... dynamic code generation doesn't seem to be used very often ?
Why ? It's rather easy to implement, once one gets the hang out of it.

Super thread revival ftw! Can't help ask, since you mention mandlebrots sets etc... Did you leave and work on that, look at the pretty colours and go into coma only to wake up now or was it more normal

Sorry, I really cant help it...

So back to android speak. Hmm. Quite popular these days isn't it

I know its not the best place, but anyone have any good tuts for setting up a development environment by any chance?

Funny to think you left before I signed up, and in that time I became a mod

Hahahahahaha. :b

To insult my injury even more, i believe my ex-girlfriend has my NDS. Can't find it anywhere. :(

Android seems interesting, but when FPC gives the opportunity to ignore all of Java (or at least most of it),
it would be even better. Don't have a clue about it yet, though ... and no Android-Device yet i could test anything on, anyway.

Wanted to buy me this http://www.archos.com/products/ta/ar...try=dk&lang=en,
but amazon says i need to pay via CreditCard first ... and i don't have one and will definitly not buy one, just for this.

Congrats for becoming a mod, btw. :D

Ooh, shiny... I believe on certain spec computers theres an android x86 project; and I've heard from VM rumours although never tried it. The incentive for android would definitely be the speed of baremetal code rather than this Java emulation yadida (I mean, when did anyone code anything intensive in Java. Eg. COD) plus it'd be super nice to get a standardised set of libs that could work on linux, windows, mac and android as well as iOS. ZenGl perhaps?

code_glitch, this example worked last I tried it. It uses the Android 2.something feature NativeActivity where a program can be started without any Java code at all. Needs a correctly configured arm-fpc crosscompiler and Ant

**21o6** · 13-07-2011, 04:37 PM

Yeah it's shiny. ^^ It slices, it dices and isn't there a dosbox for ARM ? ^^

"The incentive for android" ... what do you mean ?
Typo ? "pascal" ?

I know, for Android one has to use Java ... i didn't even know fpc was able to compile for Android before i looked at it again.

Well, native code is a HUGE plus for fpc.
Besides, this also means we can even code in assembler, and on ARM, that's awesome.
Gotta love the instructionset ! :D

Wonders me if they accept fpc-compiled programs for the Market ... but i guess not.

Never heard of ZenGL before i started looking at the forum again. I'm normally using dglOpenGL ... i'll have a look into it.
