96d538359d Merge pull request #26 from TomHarte/FactoredOut6532 
Factored out the 6532 RIOT
 2016-06-19 20:26:47 -04:00
Thomas Harte
4db61d98f4 Killed the .cpp. 2016-06-19 20:21:38 -04:00
Thomas Harte
d5aaad396e Added a TODO on my lack of knowledge. 2016-06-19 20:13:31 -04:00
Thomas Harte
7cf6008e7c Started some very basic RIOT unit tests; corrected to pass. 2016-06-19 20:12:47 -04:00
Thomas Harte
065ec618c4 Factored out and templated the 6532, finally taking the opportunity to add a means to control the on-console switches of an Atari 2600. 2016-06-19 19:36:34 -04:00
Thomas Harte
65413f078c Factored out the 6532, eventually to make it testable. 2016-06-19 18:57:40 -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

0cbf0cf8fc Merge pull request #25 from TomHarte/ElectronTyper 
Implements `Utility::TypeRecipient` for the Electron
 2016-06-19 17:29:09 -04:00
Thomas Harte
6dd8ea67c9 Tested and trimmed delay on typing if resetting. 2016-06-19 17:27:23 -04:00
Thomas Harte
05cb47709e Implemented Utility::Typer for the Electron. So that now also receives pastes. 2016-06-19 17:25:35 -04:00
Thomas Harte
ee050d71ec Merge pull request #24 from TomHarte/RAMPRGs 
Adds a check for whether PRGs should be loaded to RAM and, if so, installs them post-boot and performs a 'RUN'
 2016-06-19 16:39:03 -04:00
Thomas Harte
ef3ed1f436 Implemented full paste ability for any machine that is a typer. 2016-06-19 16:35:04 -04:00
Thomas Harte
3fc472d5cb Expanded typing to include phase for machines that need to go through multiple keypresses to reach a certain state, expanded Vic to be able to type most things (still bodged on lowercase though), and to schedule a 'run' if it's supposed to be loading into RAM, spotting that opportunity actually to do so. 2016-06-19 13:46:53 -04:00
Thomas Harte
e7aeed2f03 Established a general pattern for machines that can type things. Started working on the Vic typing itself. 2016-06-19 13:10:52 -04:00

960cae15b1 Merge pull request #22 from TomHarte/6522UnitTests 
Starts adding unit tests for the 6522, correcting the implementation as required
 2016-06-18 17:22:23 -04:00
Thomas Harte
f4915c5ad6 Fixed test and added basic implementation of data direction. 2016-06-18 17:17:03 -04:00
Thomas Harte
eea850cd12 Added a deliberately failing data direction test. 2016-06-18 16:40:01 -04:00
Thomas Harte
2282b59768 Added a quick latching test, and shortened test messages, albeit that they're still displeasingly boilerplate. 2016-06-18 16:10:46 -04:00
Thomas Harte
5d26cd85a3 Wrote test case for what appears to be correct timer behaviour if those were acting in isolation. Ensured implementation matches test case. 2016-06-18 14:30:23 -04:00
Thomas Harte
394902f409 Switched to clocking the 6522 by the half-cycle. Very trivial test now passes. 2016-06-18 13:57:10 -04:00
Thomas Harte
06fb2ff1c7 Started endeavouring to sketch out the boilerplate for writing a 6522 test harness. Added a default implementation of synchronise to the 6522 too, since not everybody is going to want one. 2016-06-18 09:28:46 -04:00
Thomas Harte
595791cee0 Made the base 6522 class more abstract: you must now opt-in if you want the IRQ line to be sent to a delegate. 2016-06-18 08:51:18 -04:00
Thomas Harte
60d654e9f9 Whoops; they're all .bin. No .roms here. 2016-06-17 08:27:16 -04:00

d6cb4fe15c Merge pull request #21 from TomHarte/LowLatencyAudio 
Attempts to apply some sort of quality-of-service guarantee to audio
 2016-06-16 21:44:16 -04:00
Thomas Harte
090e92ad26 Making this large has very limited side effects. So why not? 2016-06-16 21:41:17 -04:00
Thomas Harte
3b71d1a309 Switched to a variable-length buffer based on attempting to hit approximately a certain quality of service. 2016-06-16 21:35:22 -04:00
Thomas Harte
2ee78d42b9 Made an attempt also to trigger updates upon audio packets being returned, and significantly to reduce the size and quantity of those. This should get down to 11ms latency if the output wave is 44100; I might need to scale up the buffer size as the sampling rate increases or this is going to get crazy at 192Khz. 2016-06-16 20:51:35 -04:00
Thomas Harte
00a9f1bf24 Fixed best-effort updater actually to run, finally moved clock rate announcement into the C++ side of things, started working on a mechanism to allow clock rate to be updated. 2016-06-16 20:39:46 -04:00
Thomas Harte
1921a6c469 Rewired the existing cause-an-update route from the OpenGLView through the best-effort updater. 2016-06-16 18:19:23 -04:00
Thomas Harte
530cf3dcbb Made an attempt to consolidate serialisation and clock rate adherence, allowing a floating-point clock rate. 2016-06-16 18:04:54 -04:00
Thomas Harte
ce59ad1911 Minor on-disk shuffle, to try to clarify ownership of responsibility. 2016-06-15 08:11:30 -04:00
Thomas Harte
45999f5b26 This should be strong. 2016-06-15 08:07:59 -04:00
Thomas Harte
e0baaf17f1 Added class prefix. 2016-06-15 08:07:25 -04:00
Thomas Harte
695dd2e9e3 Started upon a delegate protocol for the AudioQueue, resolving my use of a deprecated API while I'm at it. 2016-06-15 07:35:34 -04:00

dbdd05afb8 Merge pull request #20 from TomHarte/6560Accuracy 
Adds some documentation and support for inverted cells in the 6560
 2016-06-14 21:07:44 -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

8c82f6ae37 Merge pull request #18 from TomHarte/Vic-20 
Adds basic NTSC VIC-20 emulation.
 2016-06-14 18:20:06 -04:00

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
a9036e7aa4 Increased buffering range of audio as a quick fix for now. Basically means: increased latency as a short-term fix. 2016-06-14 07:31:47 -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

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
fcf4b14344 Extended to allow floating-point sampling rates. Which makes sense. 2016-06-13 19:30:41 -04:00
Thomas Harte
4190b42bbb No need for these to live separately, I think. 2016-06-13 18:27:18 -04:00
