Doubles down on <cX> over <X.h> for C includes, and usage of the namespace for those types and functions.

Enables -Wreorder and corrects a few of the more trivial fixes thereby suggested.

Modifies the Vic-20 and C1540 to bring them into the realm of self-ROM fetching.
...
Hence enables Vic-20 support within kiosk mode as currently drafted.

Completes clean-up of post-formalisation per-machine keyboard code.
...
At least for now. Standardising on how column + row is encoded might be helpful.

Relocates things that were in Machines/ for machine usage.

Transfers possession of keyboard mappings from the Mac side over to individual machines.

Specifically by establishing an intermediate representation of a useful mix between the American and British IBM and Mac keyboard layouts, and routing through that.

Causes the ZX80/81 to omit support for the wait line if being configured as a ZX80.

4a66dd9e82
Arranges for the ZX80/81 to get a peek at target configuration prior to construction. I'm as yet undecided on whether to make this the norm.
2017-08-27 16:42:16 -04:00
Thomas Harte
57bfec285f
Makes it optional whether the Z80 supports the wait line. If the wait line isn't in use, runtime costs are decreased because the optional wait cycles need not be iterated over.
2017-08-26 23:08:57 -04:00
Thomas Harte
ee71be0e7e
Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.
2017-08-21 21:56:42 -04:00
Thomas Harte

Allows Z80 users to opt out of support for the bus request line. Which both now do.

Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine.
2017-08-17 10:48:29 -04:00

Ensured the ZX80 and '81 also provide the necessary hook for destruction.
2017-08-11 12:11:01 -04:00

dd4bc87d52
Fixed: should be a full-path #ifdef guard, given that this is one of the classes named relative to its namespace.
2017-08-11 11:21:33 -04:00
Thomas Harte
575b1dba75
Formally declared the ZX80/81 and Amstrad CPC as keyboard machines in their public interface. Which means not having to repeat the meaning of set_key_state and clear_all_keys. So: a minor DRY improvement.
2017-08-03 12:38:22 -04:00

bbb17acf3a
Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.
2017-08-03 11:50:50 -04:00
Thomas Harte
ad3a98387f
Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.
2017-08-03 11:42:31 -04:00

These should actually both be in the public header, as the types are used in an exposed method.
2017-08-02 22:18:30 -04:00
Thomas Harte
6d510e4e70
Made it no longer public knowledge that any sort of Typer is involved in being a ZX80/81.
2017-08-02 22:17:22 -04:00
Thomas Harte
8e0736fbe6
Reinstated typing ability, albeit with an ugly inline insertion. But I think I can defer dealing with typers to another pull request. The whole issue of keyboard mapping probably needs reappraisal.
2017-08-02 22:16:09 -04:00
Thomas Harte
681d1e2f8d
Breaking its typer for now, adapted the ZX80/81 to having a Z80, not being one.

4abd62e62b
Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.
2017-07-27 22:05:29 -04:00
Thomas Harte
968d2bb8ba
Brought Typer into the new run_for orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.
2017-07-27 21:53:45 -04:00
Thomas Harte
8848ebbd4f
Formalised set_interrupt_line's optional parameter as being a count of HalfCycles; corrected PartialMachineCycle.is_wait and effected the proper timing for counter reset on a ZX81.
2017-07-27 21:10:14 -04:00
Thomas Harte
8361756dc4
Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.
2017-07-27 07:40:02 -04:00
Thomas Harte
81a3899381
Adjusted the Z80 formally to communicate in terms of half cycles rather than whole.
2017-07-26 19:42:00 -04:00
Thomas Harte
966b5e6372
Adapted the Z80's perform_machine_cycle to return Cycles.

Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.
2017-07-25 20:20:55 -04:00
Thomas Harte
a1e9a54765
Eliminated redundant uses of ClockReceiver and sought to ensure that proper run_fors are inherited all the way down.
2017-07-25 20:09:13 -04:00
Thomas Harte

Converted the TimedEventLoop and the things that sit atop it into ClockReceivers.
2017-07-24 21:19:05 -04:00

Decided to follow through on Cycles and HalfCycles as complete integer-alikes. Which means giving them the interesting range of operators. Also killed the implicit conversion to int as likely to lead to type confusion.
2017-07-24 20:10:05 -04:00
Thomas Harte
ba088e5545
Adapted the Z80 into a clock receiver, which also vends Cycles rather than a raw int within its PartialMachineCycle struct. The objective is to update it to vend HalfCycles within its struct, but I think I need to do some work on cycle/half-cycle arithmetic first.
2017-07-23 22:15:04 -04:00

Converted the ZX80/81 video component into a ClockReceiver. As it happens, it's most convenient to take the half-cycle bus here.
2017-07-22 23:02:28 -04:00
Thomas Harte

Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.

Factored out the table-lookup approach to being a typer, and adjusted so as definitely to limit myself to positive offset table lookups.
2017-07-21 21:18:51 -04:00
Thomas Harte
2471ef805b
Fixed signed/unsigned comparison and potential negative table reference.

Chopped time accumulation out of the default Tape process because it's proving to be sufficiently expensive for a TZX as not to be worthwhile. Introduced a cheaper position capturing/restoring method.
2017-07-21 18:55:03 -04:00
Thomas Harte
44e5a03cf2
Removed just-don't-power-the-tape approach to pausing and playing, in favour of being fully communicative.
2017-07-19 19:21:27 -04:00

Added enough typing to issue a load command. No thoughts as to running yet though.
2017-07-09 22:07:12 -04:00

Added basic Typer support for the ZX80 and '81.

Hardens the ZX80/81 video routines to ensure they never try to push data into the future and don't double-count time when pixels would ostensibly run into sync. You could previously see the CRT being handed negative run lengths if sync interrupted pixels or if a run of more than 320 pixels (my arbitrary buffer size) occurred, with corresponding poor behaviour given my use of unsigned numbers.
2017-07-09 19:33:05 -04:00

Moved line counter reset logic; I think this is actually correct.

By observation, it appears that disabling vsync occurs on any port output whatsoever, as long as NMI isn't blocking it.
2017-07-08 21:01:52 -04:00
Thomas Harte
30e93979d2
Removed data work if sync is enabled; in that case no data is output.
