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
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
75d67ee770 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
40339a12e1 Formalised the use of a cycles count with a divider, bringing a few additional plain-int users into the fold. 2017-07-25 07:15:31 -04:00
Thomas Harte
a1a3aab115 Fixed implicit sign conversion. 2017-07-24 22:40:15 -04:00

c77a83d86f The 6560 is now a ClockReceiver. This reduces to zero the number of remaining instances of the text run_for_cycles in this codebase. 2017-07-24 22:38:35 -04:00
Thomas Harte
b7f88e8f61 Filter is now a ClockReciever, affecting all sound output devices. 2017-07-24 21:29:13 -04:00
Thomas Harte
12f7e1b804 Enshrined a default colour burst amplitude. Which now everybody relies on. The 102 figure is derived from the burst apparently being 40 IRE. 2017-07-07 23:35:14 -04:00
Thomas Harte
eb8a2de5d6 Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80. 2017-05-15 07:38:59 -04:00
Thomas Harte
e270b726b3 Tweaked blue, increased saturation. 2017-05-13 22:01:02 -04:00
Thomas Harte
44ce7fa54c Corrected luminances across the board, and PAL colours. 2017-05-13 21:50:09 -04:00
Thomas Harte
b0142cf050 Made an updated stab at NTSC colours. 2017-05-13 14:29:36 -04:00
Thomas Harte
a340331229 Introduced 1-bit of saturation, returning black and white as black and white. 2017-05-11 21:31:58 -04:00
Thomas Harte
15d17c12d5 Switched the 6560 to two bytes per pixel, since one isn't sufficient for precision and because mixing up the implementation might help me to figure out what's amiss. 2017-05-09 21:22:01 -04:00
Thomas Harte
5998123868 Added some consts, for a minor safety improvement. 2017-05-06 19:53:24 -04:00
Thomas Harte
e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00

ca50606e1d Restored Vic audio. 2016-12-03 17:10:47 -05:00
Thomas Harte
36bc558798 Converted all 'Components' to postfix underscores. 2016-12-03 10:51:09 -05:00
Thomas Harte
eeec516fa6 Implemented seeking on tapes, mucked about a bit more with the Commodore analyser, at least temporarily removed cropping from the Vic emulator. 2016-09-11 17:09:00 -04:00
Thomas Harte
c783090980 It turns out that the Vic has a 1.6Khz low-pass filter. So added that. 2016-08-21 12:13:41 -04:00
Thomas Harte
99157ad6b2 Ensured the 6560 knows its real audio clock on a PAL machine; removed some stray semicolons. 2016-08-19 13:35:34 -04:00
Thomas Harte
902c0f967a Implements known phase pattern for PAL output. 2016-08-17 08:09:48 -04:00
Thomas Harte
142774be37 Collapsed 6560 template to a more direct loop, albeit with quite a bit still left to fix. 2016-08-09 21:10:53 -04:00
Thomas Harte
12bad8f23f Turned the 6560 into an ordinary template, similar to the rest of the project, albeit right now with a fairly shonky internal implementation. Fixed a Mac-specific interface sizing issue. 2016-08-09 20:41:05 -04:00
Thomas Harte
3e65450a54 Converted the 6560 fully into a template; worked on allowing the typer to run at a much faster rate where hardware has some trigger by which it can request the next key. 2016-08-06 14:33:24 -04:00
Thomas Harte
c6e046253e Shunted code for the main part up into the header, in advance of turning it into a template so as to bring it inside the normal orthodoxy. 2016-08-05 19:13:49 -04:00
Thomas Harte
88964ceac0 Eliminated plain pointer passing for object types. 2016-07-04 19:33:55 -04:00
Thomas Harte
de5d2f1113 Ensured the line counter increments late on NTSC. 2016-06-27 22:12:55 -04:00
Thomas Harte
359ffb9aa7 Made some attempt to implement what appears to be the proper address generation logic. 2016-06-23 07:32:24 -04:00
Thomas Harte
b753690d5e Made an attempt to adjust the 6560 to a model compatible with that advocated by the available documentation. Exact decision timing may need further work. 2016-06-21 22:12:01 -04:00
Thomas Harte
ce2f5515c0 Made some minor documentation improvements, killed 6522.cpp as the 6522 is going to be a template only, attempting to promote good inlining behaviour. 2016-06-19 18:11:37 -04:00
Thomas Harte
ce7488dd30 Added support for _invertedCells. Treading water a little before making real changes. 2016-06-14 21:06:29 -04:00
Thomas Harte
926f819e3b Added some documentation, made the speaker private. 2016-06-14 20:00:16 -04:00
Thomas Harte
fdc854c0c2 Fixed tone channels; made an attempt at loading PRGs that are supposed to go into RAM. 2016-06-13 21:49:59 -04:00
Thomas Harte
efcb196ef7 Made a complete attempt at the tone channels. 2016-06-13 20:59:01 -04:00
Thomas Harte
5fc36b956c Attempted most basic sketching of a container for Vic audio. 2016-06-13 19:30:52 -04:00
Thomas Harte
e10535181d Made an attempt to implement interlaced video. 2016-06-12 22:27:58 -04:00
Thomas Harte
4c2b964cd4 Added NTSC-VIC's switching of phase every field. 2016-06-12 17:45:25 -04:00
Thomas Harte
1a2b18f93b Steps towards CPU mapping; diagnostic. 2016-06-12 17:27:57 -04:00
Thomas Harte
ed76e36b18 Made basic attempt at 16-line character mode. 2016-06-12 11:23:57 -04:00
Thomas Harte
c7c55528e2 Realised that registers appear also to be readable. 2016-06-06 20:29:39 -04:00
Thomas Harte
e8cb674073 Made some attempt at colours, at least. 2016-06-06 20:18:24 -04:00
Thomas Harte
64539a2b24 Advanced to having some characters displayed, even though they're obviously very much incorrect and the display is still rolling. 2016-06-06 07:35:35 -04:00
Thomas Harte
79e05a2413 Without yet figuring out what vertical sync is meant to do, moved just about far enough forwards to see _something_ that hopefully I can soon discern characters within. 2016-06-05 18:02:49 -04:00
Thomas Harte
444d3b69b6 Made some elementary attempt to hit something like the correct states within the VIC. 2016-06-05 17:06:10 -04:00
Thomas Harte
9e9e50edb1 Added guess on how colour memory and the 12-bit bus possibly works. 2016-06-05 16:28:06 -04:00
Thomas Harte
3be1ce457b Made some attempt at discerning fields. 2016-06-05 14:05:31 -04:00
Thomas Harte
9566c87532 Added enough to the machine that the 6560 can now produce output if it wishes. 2016-06-05 12:11:12 -04:00
Thomas Harte
f922d38ed2 The Vic now captures the ROMs sent to it and has just enough infrastructure to get to a black screen. Progress! 2016-06-05 10:51:07 -04:00
