[RCC16] Code optimizer

I finaly managed to compile Contiki, and it even runs. Not particularly well, and it is quite FAT (well I am not sure that I managed to include the very same modules than what Carlsson included, anyway). One reason of this fatness, is due to the way the opcodes are generated from a pseudo assembly l...

Ok, I found out the difference between using static or not in the above code.

Without static we got that:

Code: Select all

_pf
	DW(_r1)
_r1
	RET
_main
	RET
while with static we got this:

Code: Select all

_pf
	DW(Ltest65)
Ltest66
	RET
_main
	RET
Obviously there is something bad in the label allocation.

[RCC16] Error with static function pointers

I have been trying to compile Contiki with the OSDK, and got many problems, some I solved by hacking, some by correcting problems in the compiler/assembler/linker, but some I failed to solve, in particular some stuff in ctk.c that basicaly do the following: static void r1(); void (*pf)()=r1; static ...

CC65 vs OSDK ?

So far we had no really significant set of data allowing us to efficiently compare the quality of CC65 compared to the C compiler used in the OSDK. Interesting comparison points are: - ANSI compatibility - Size of generated code - Speed of generated code I guess I could try to recompile Contiki usin...

Yep, so far there is not much things to do with it, but at least it works :)

I guess we could also probably try to find a way to draw nice window borders instead of + = and | :lol:

And yes, with 28 usable lines the Oric is definitively one of the machines that can display the most things.

You can also probably use #defines to do that, something like:

Code: Select all

 #define txy .byt $42

Loading and Saving from tape

I decided to reply to the post in Contiki http://forum.defence-force.org/viewtopic.php?t=29&highlight= here to keep it a bit more focused. Here are the (crapy) routines I used in my first demo (1997) and that I reused in ULA paint for loading and saving pictures... Basicaly it does the same thing th...

Re: XA and undocumented/illegal opcodes

I read the XA assembler doc, and to me, it doesn't support any illegal/undocumented 6502 opcodes. In the source code of XA is the following table: /* 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 imm */ { -1, 0x65,0x75,-1,0x172,0x61,0x71,0x469,0x6d,0x7d,0x79,-1, -1, -1, -1, -1, -1,0...

Re: Contiki on Oric Atmos?

From my experience with the VIC-20 port, it appears that about 40K of available RAM is the least required to get Contiki running with a basic window system and network support. Can Contiki works purely in a 40x28 characters video text mode ? If yes, then well that's easy, all the memory from $500 t...

I guess we identified two main needs: 1) A more evolved operating system that would be closely compatible to something that exist on other machines in order to ease the communication between Oric and other machines (ex: MS-DOS compatibility to make it easy to read and write from a PC), while also ha...

It would be nice also that you indicate what are the characteristics of your disc system (Jasmin 1 or 2, single head or double head, 3" or 3.5" or 5.25", number of drives you have, etc...) This is why I voted "other", because "Microdisc connected to a Telestrat" seemed to refer to a 3" drive, but I...

Poll: Which is the storage system you do use ?

Ok, there's been some talkings recently about the representation of the various kind of oric hardware, and I guess it is kind of important to know who has what, and who uses what. Typicaly I would tend to say that a significative number of English people never cared about the Telestrat or Jasmin dri...
