Oliver Schmidt a5d7a06027 Enhanced Ethernet drivers.
Made Ethernet drivers easier to consume by assembly programs.
* Replaced function pointers with JMP instructions.
* Provide return values additionally via Carry flag.

Reset Ethernet chips on initialization.
Both for the CS8900A and the W5100 the data sheets just say that
the RESET bit is automatically cleared after the RESET. This may
be interpreted in two ways:
1) There's no need to be afraid of reading the RESET bit as 1 and
unintentionally trigger a RESET by writing it back after ORing in
some other bit.
2) The RESET process isn't complete before the RESET bit hasn't
become 0 again.
It's impossible for me to empirically falsify the latter option
as the drivers are supposed to work on faster machines than the
ones I have access to. And if the RESET process includes things
like oscillators then the time to complete the RESET could differ
even between multiple exemplars of the same chip. Therefore I
opted to presume the latter option.
However that means a non-exsistent chip may cause an infinite
loop while waiting for the RESET bit to be cleared so I finally
added code to detect the presence of the Ethernet chips. There's
a risk of a chip being locked up in a way that makes the detection
fail - and therefore the RESET not being performed. This catch-22
needs to be solved by the user doing a hard RESET.

Oliver Schmidt fc983e2e79 Copied 'contiki_arg[c|v]' from 'native' to the other desktop targets.
- On the retro targets support for 'contiki_arg[c|v]' is optional as accesing arg[c|v] is rather expensive.

Oliver Schmidt 510678bed0 Added mouse support for the Atari. 2014-01-20 22:51:40 +01:00
Oliver Schmidt a24865de72 Add somewhat more support to use different mouse drivers.
- The default mouse driver is now always named 'contiki.mou'.
- Alternative mouse drivers are present in the disk images.
- Users can select their mouse driver by renaming the files.

Oliver Schmidt 3b2173e01f Have CBM DOS filetype of imported files match the one used by cc65.
CFS_WRITE implies O_TRUNC which is implemented on CBM DOS by deleting an
exsisting file. Hoewever this succeeds only if the CBM DOS filetype matches.

We need a working O_TRUNC in order to be able to overwrite the contiki.cfg
configuration file.

Note: Now it has be clarified why overwriting the configuration file started to
fail the CBM PFS (platform file system) can be activated for the recently added
ethconfig program.

Oliver Schmidt 9cdc6da040 Avoid access to the address register during auto-increment.
It cannot be ruled out that access to the address register triggers
an address auto-increment. Therefore a temporary address register
shadow is introduced to replace the access to the address regsiter.

Additionally there are several minor beautifications.

Oliver Schmidt 2263c1aa55 - Optimized LAN91C96 driver for speed and size.
- Speed: The primary byte copy loops are reduzed to the bare minimum by adjusting the base pointer 'ptr' and loop register 'y' in such a way that the 'y' overflow matches the low byte of the loop size.

- Introduced a loop for setting the MAC address.

Additional minor fix:

- Properly start self modification with first location.

Oliver Schmidt ea08635ca4 Optimized CS8900A driver for speed and size.
- Speed: The primary byte copy loops are reduzed to the bare minimum by adjusting the base pointer 'ptr' and loop register 'y' in such a way that the 'y' overflow matches the low byte of the loop size.

- Size: Factored out all repeated code into subroutines. Introduced a loop for setting the MAC address.

Additional minor changes:

- Activate frame reception as last step of initialization after CS8900A configuration.

- Properly set internal address bits used by the CS8900A.

Peter A. Bigot 5fc0575e99 Makefile.include: support make clean all
Historically $(OBJECTDIR) was created when Makefile.include is read.  A
consequence is that combining "clean" with "all" (or any other build
target) results in an error because the clean removes the object
directory that is required to exist when building dependencies.
Creating $(OBJECTDIR) on-demand ensures it is present when needed.

Removed creation of $(OBJECTDIR) on initial read, and added an order-only
dependency forcing its creation all Makefile* rules where the target is
explicitly or implicitly in $(OBJECTDIR).

Oliver Schmidt 61b90c0126 We actually need PROJECT_OBJECTFILES and PROJECT_LIBRARIES for retro builds too. 2013-02-16 22:57:50 +01:00
Oliver Schmidt 98060c1eab Moved from last cc65 release (2.13.3) to recent cc65 snapshot (2.13.9).
Relevant cc65 changes...

General:
- The compiler generates "extended" dependency info (like gcc) so there's no need for postprocessing whatsoever :-)
- The linker is very pernickety regarding the ordering of cmdline options so a custom linker rule is necessary :-(

Apple2:
- The various memory usage scenarios aren't specified anymore via separate linker configs but via defines overriding default values in the builtin linker config.

Atari:
- The builtin linker config allows to override the start addr so there no more need for a custom linker config.
- The C library comes with POSIX directory access. So there's no more need for for a custom coding.

CBM:
- The C library comes with POSIX directory access. So there's no more need for for a custom coding.
