Thomas Harte
e1aa3e5a7f Imports chrominances from the TED documentation. They seem to apply to the VIC-I also. 2018-03-29 20:04:37 -04:00

Thomas Harte
48737a32a7 Introduces formal setting of the output volume to SampleSource.
Previously every output device was making its own decision. Which is increasingly less sustainable due to the CompoundSource.
2018-03-09 13:23:18 -05:00
Thomas Harte

Thomas Harte
c0055a5a5f Further builds up SConstruct, correcting many missed imports and a couple of improper uses of C99 in C++ code. 2017-11-09 22:04:49 -05:00
Thomas Harte
ad9df4bb90 Commutes uint8_t *, uint16_t *, uint32_t *, size_t, off_t and long to functional-style casts. 2017-10-21 22:30:15 -04:00

Thomas Harte
edb9fd301c Begins this project's conversion to functional-style casts. 2017-10-03 22:04:15 -04:00
Thomas Harte
e208f03636 Corrects the US colour palette, effectively undoing what was a mistaken adjustment for the time when Oric-centric phase alignment was built into the CRT based on a false calculation that it wouldn't affect the machines that generate chrominance functionally. 2017-08-16 09:58:34 -04:00
Thomas Harte
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
Thomas Harte
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
Thomas Harte

Thomas Harte
36bc558798 Converted all 'Components' to postfix underscores. 2016-12-03 10:51:09 -05:00
Thomas Harte
922dd6a586 Hit up the other two kinds of audio generator. 2016-10-07 17:10:00 -04:00
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
1541273785 Moved responsibility for throwing in a low-pass filter up to the Vic, appropriately. 2016-08-21 18:13:31 -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
8d839c5278 I think this is correct. And have explained why. 2016-08-20 16:54:43 -04:00
Thomas Harte
7c9455251d Fixed reload for the lower-frequency audio channels. 2016-08-19 17:34:01 -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
5d40d70c92 Fixed 6560 addressing error, added an autotyper for Vic disks (more work potentially needed), fixed semantics for testing whether a 6502 is about to reset. 2016-08-01 10:32:32 -04:00
Thomas Harte
88964ceac0 Eliminated plain pointer passing for object types. 2016-07-04 19:33:55 -04:00
Thomas Harte
5c85366de2 Made an attempt to prevent spurious border colour pushes. 2016-06-29 21:22:26 -04:00
Thomas Harte
ff53accca0 Demonstrated that issue is coloured borders, made a guess as to buffer exhaustion, upped limits as a temporary fix. 2016-06-29 21:16:34 -04:00
Thomas Harte
0182b0483a Added a 'power on' flag that is set automatically at construction but can be declined. Saves all that stuff of every machine having to set and then unset the RST line, and fixes an Electron bug related to that. 2016-06-29 19:13:24 -04:00
Thomas Harte
de5d2f1113 Ensured the line counter increments late on NTSC. 2016-06-27 22:12:55 -04:00
Thomas Harte
3c9183d034 Improved some commenting. 2016-06-23 20:43:29 -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
106e56600d Added a DC offset for 6560 volume level, albeit one plucked from thin air. 2016-06-21 07:31:14 -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
a2a6e3c818 Fixed phase offsets. 2016-06-14 18:19:06 -04:00
Thomas Harte
f4884a3481 Added the noise channel, albeit not very creatively. 2016-06-14 17:50:32 -04:00
Thomas Harte
c18cc4c8f5 It appears the Vic's output is sine-ish, after all. Also adjusted centre of display, simultaneously adding some validation on that. 2016-06-14 07:29:35 -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
f1a45c1011 Merge branch 'VicAudio' into Vic-20 2016-06-13 19:34:13 -04:00
Thomas Harte
2d23bc46f2 Whoops; fixed line count target test. 2016-06-13 19:34:01 -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
91c406e065 Made an attempt to honour interlaced-frame line counts. 2016-06-13 18:21:21 -04:00
Thomas Harte
2e946e785f Settled on half-intensity colour for now, appears likely not to be too incorrect(?) 2016-06-13 18:20:21 -04:00
Thomas Harte
e10535181d Made an attempt to implement interlaced video. 2016-06-12 22:27:58 -04:00
Thomas Harte
4ad55a7f5e Trimmed the visible area. 2016-06-12 18:01:38 -04:00
Thomas Harte
a5efa7543a Added vertical sync, switching fully to the normal NTSC colour space. 2016-06-12 17:57:52 -04:00
Thomas Harte
4c2b964cd4 Added NTSC-VIC's switching of phase every field. 2016-06-12 17:45:25 -04:00
Thomas Harte
6b5a322918 Fixed all colours, plus special case no-chroma for black and white. 2016-06-12 17:41:52 -04:00
Thomas Harte
580c8bdcbd Ported rest. 2016-06-12 17:29:44 -04:00
Thomas Harte
1a2b18f93b Steps towards CPU mapping; diagnostic. 2016-06-12 17:27:57 -04:00
Thomas Harte
8abf395202 Experimented with table-based GLSL lookups, and a sine curve. Now _exceedingly_ slow, but colours are correct if I pretend I'm in the YUV colour space. 2016-06-12 14:57:24 -04:00
Thomas Harte
2992183aae Switched to a lookup table for phase, temporarily in YUV colour space, probably. Working on it. 2016-06-12 14:39:17 -04:00
Thomas Harte
ed76e36b18 Made basic attempt at 16-line character mode. 2016-06-12 11:23:57 -04:00
Thomas Harte
1ed04fae1e Resolved 6560 addressing. 2016-06-10 18:12:21 -04:00
Thomas Harte
f3b1d7de82 ... and that's a flashing cursor. Keyboard input next! 2016-06-09 22:37:59 -04:00
Thomas Harte
30b7db3979 Attempted a square wave, made the Vic itself responsible for address manipulation re:the 6560. 2016-06-09 22:05:17 -04:00
Thomas Harte
e99055bedb Attempted switching back to a square wave for the composite video and otherwise implementing what's necessary to get to that flashing cursor — the 6560 returns its scan line and the timing bits of the 6522 are appearing. 2016-06-08 22:15:24 -04:00
Thomas Harte
581eace478 Increased logging slightly, ensured all of colour RAM can be read, slightly improved the 2600 pixel decoder. 2016-06-07 22:01:14 -04:00
Thomas Harte
26ab96868a Decided to turn the 6522 into a template, since it's a per-cycle thing with variable behaviour. Added appropriate memory map callouts to hit the two in the Vic. Though they don't yet do anything. 2016-06-07 19:15:18 -04:00
Thomas Harte
6522530e1c Actually, I'm dithering over whether the 6522 should be an ordinary class or a curiously-recurring template. But it'll need a file, definitely. 2016-06-06 21:56:02 -04:00
Thomas Harte
ca23e2e10a This now proceeds to an ostensibly working basic prompt. Colours are wrong, 6560 is probably very wrong, 6522 is still absent. Hence no cursor. 2016-06-06 20:33:06 -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
89c87c3e81 Some major hackiness gives the first line of expected text repeating endlessly (as the end of columns is never reached, as that's back to thinking it's 0x7f); I also don't yet know which actor is supposed to do the '+0x8000' (which probably shouldn't be that but might be a pin on the 6560 indicating what sort of value is being fetched, that effects chip select for the various bits of memory?) 2016-06-06 07:47:30 -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
