Thomas Harte
1c5972f7b0 Ensures NTSC raster count rollover; previously it was positing a line '261' for half of '0'. 2018-04-08 16:18:41 -04:00
Thomas Harte

Thomas Harte
60c1da6a66 Causes the 6560 to obey set_sample_volume_range.
Thereby resolves a clipping issue.
2018-04-05 21:04:46 -04:00
Thomas Harte

Thomas Harte

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

2018-03-22 21:59:19 -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
ac80d10cd8 Separates the component parts of running an audio stream: task deferral, filtering and generation.
Walking towards improving opportunities for composition.
2017-12-17 21:26:06 -05:00
Thomas Harte

Thomas Harte
5408efe9b5 Flags obvious default options within the 6560, Vic-20 and DynamicMachine. 2017-11-12 16:41:09 -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
5e3e91373a Switches all unsigned int and double casts to functional style. 2017-10-21 19:49:04 -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

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
