81e6cc34e5 Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus. 2016-07-07 06:57:21 -04:00
Thomas Harte
c9479f923b The inversion of truth was clearly just a problematic API. Got explicit. LineLevel might need to become more pervasive. 2016-07-07 06:44:13 -04:00

dcb86a027a Okay, so the 1540 doesn't toggle the actual attention line. I don't know what it does yet but this helps. 2016-07-06 22:31:14 -04:00
Thomas Harte
1baf21827c Since the ROM is well disassembled, let's actually try to be a 1541 first. 2016-07-06 22:17:32 -04:00
Thomas Harte
4f174786b5 Fixed potential buffer overrun. 2016-07-06 21:39:09 -04:00

f64cd8cfcb Quick fixes properly to declare the DriveVIA, to ensure its interrupts take effect, and to wire ATN IN to CA1 rather than CB2. 2016-07-06 20:22:46 -04:00
Thomas Harte
428fcdb978 Centralised and improved serial logging. 2016-07-06 07:46:21 -04:00
Thomas Harte
8819711bc8 Threw in the second VIA as a currently clearly incorrect thing. 2016-07-05 22:22:09 -04:00
Thomas Harte
602e7f01c7 Control lines seem to have evolved to pure push. 2016-07-05 21:15:29 -04:00

93c2bb80a2 Improved a comment, added independent C[A/B]2 input mode. 2016-07-05 21:11:51 -04:00
Thomas Harte
6c4fa4ec5d Improved commenting and initial state communication. 2016-07-05 20:57:31 -04:00
Thomas Harte
1e6d90de17 Made an attempt properly to deal with initial bus state. 2016-07-05 20:52:33 -04:00
Thomas Harte
1bb109a23b Made a quick attempt at basic C[A/B]2 interrupts. 2016-07-05 20:39:15 -04:00
Thomas Harte
c3b7d24293 It appears that the attention line is also wired to CB2. So the ball is back in the 6522's court. 2016-07-05 19:19:46 -04:00
Thomas Harte
11fc43aa04 Made an attempt to allow the 1540 to talk back to the Vic, and to receive interrupts. Also slightly disambiguated debugging logging. 2016-07-05 19:12:43 -04:00
Thomas Harte
d16b79073e Further fleshing out: added a serial port for the serial bus. 2016-07-05 17:27:02 -04:00
Thomas Harte
d1eea6943d Ensured the 1540 ROM gets installed, at least. 2016-07-05 16:54:25 -04:00
Thomas Harte
47548dcedc Fixed an erroneous #import. 2016-07-05 16:39:31 -04:00
Thomas Harte
86dabd007b Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful. 2016-07-05 16:39:18 -04:00
Thomas Harte
a25fcc7190 Made a first attempt at wiring back serial port input. 2016-07-05 16:10:54 -04:00
Thomas Harte
d2cded7b59 Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic. 2016-07-05 14:55:20 -04:00
Thomas Harte
0d3d0fbe4d Created a namespace for Commodore and an empty container file for the 1540[/1] implementation. 2016-07-05 13:28:27 -04:00

1cc83dc0a0 Merge pull request #38 from TomHarte/VicJoystick 
Vic: Adds support for a toggleable joystick-via-keyboard mode and wires in one side of a serial port
 2016-07-05 11:05:55 -04:00
Thomas Harte
97751a9d86 Took the preliminary steps necessary to wire up a serial port. 2016-07-05 10:55:47 -04:00
Thomas Harte
df4724eb3e Added a modal toggle allowing the keyboard to be switched between being a keyboard and being a joystick for the Vic. 2016-07-04 22:01:07 -04:00
Thomas Harte
a49f2b41cc Added C++ side of things. I think. 2016-07-04 21:48:25 -04:00
Thomas Harte
fef316932f Moved opening bracket appropriately. 2016-07-04 21:14:28 -04:00
Thomas Harte
8db44eed3e Added a default implementation of Speaker::skip_samples. 2016-07-04 20:48:27 -04:00
Thomas Harte
bfa237397d Settled on assigning to nullptr as the appropriate style for emptying shared_ptrs; fixed the Vic properly to release its output resources. 2016-07-04 20:34:11 -04:00

6851a1b63b Merge pull request #37 from TomHarte/C++Style 
Eliminates plain pointer passes for object types

88964ceac0 Eliminated plain pointer passing for object types. 2016-07-04 19:33:55 -04:00

6dbf16210b Switched protocol to meaningful name and corrected its omission from the repository. 2016-07-04 19:19:07 -04:00
Thomas Harte
82b0bc9b58 Discovered that this is another meaningful usage of using. 2016-07-04 19:10:10 -04:00
Thomas Harte
df533874f0 Merge pull request #36 from TomHarte/Better6522 
Added communication of the static level 6522 control line outputs and slightly simplified the Vic's memory bus
 2016-07-02 19:07:35 -04:00
Thomas Harte
7e5b631e30 Cut some dead code. 2016-07-01 19:02:29 -04:00
Thomas Harte
7fa010a463 Attempted to add support for the most basic of control line output, and slightly to optimise the Vic. 2016-07-01 19:01:22 -04:00

2bc87ee095 Merge branch 'master' of github.com:TomHarte/CLK 2016-07-01 16:28:18 -04:00

eefd0c17b6 Actually, I guess that to fulfil the contract I can't silently decide not to draw if I'm being told I definitely need to draw. 2016-07-01 16:27:45 -04:00
Thomas Harte
ed8f4d0476 Added some minor additional bits of documentation. 2016-06-30 08:46:29 -04:00

4ac619f569 glClientWaitSync appears to be a busy wait, at least on my machine. But why wait indefinitely anyway? 2016-06-29 21:32:47 -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

7f10616be9 Merge pull request #35 from TomHarte/BRKDiversion 
Adds a small amount of test coverage to the functioning of 6502 interrupts
 2016-06-29 21:03:19 -04:00
Thomas Harte
41809d4597 Made an attempt at NMI usurption of IRQ/BRK. 2016-06-29 20:59:45 -04:00
Thomas Harte
c02226bc41 Ensured stack pointer goes the right way upon reset. 2016-06-29 20:42:26 -04:00

b322baff2f Added CLI/SEI pair test. 2016-06-29 19:42:39 -04:00

db7c6430b5 Fixed Klaus Dormann termination condition. 2016-06-29 19:16:34 -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

bff53775ad Update README.md 
Corrected typo and resulting logical error; it's definitely 227.5 subcarrier cycles per line, NTSC fans!
 2016-06-29 11:12:03 -04:00
Thomas Harte
6419d9c485 Added a single IRQ test case, discovering that I'm two cycles short. Whoops! 2016-06-28 21:29:43 -04:00
