d8334edf4a Started trying to clean up, including commuting the C1540 source file name to match its class name but mainly by adding documentation. 2016-07-10 07:46:20 -04:00

c0ab45a73d Disabled a bunch of the caveman debug logging. 2016-07-09 22:29:11 -04:00
Thomas Harte
f589d639db Okay, so it seems that sync also works the other way around. 2016-07-09 22:25:44 -04:00
Thomas Harte
693c8b2438 After all that, it seems likely that inputs just aren't inverted for the Vic. 2016-07-09 20:03:38 -04:00

656cd211d7 Was transmitting bit levels backwards (probably?); 1540 now acknowledges byte received. 2016-07-09 18:06:49 -04:00
Thomas Harte
01746f0512 This is probably a valid test. But I'm not completely sure. Time to figure out what's happening on the 1540 end. 2016-07-09 18:01:04 -04:00
Thomas Harte
cd84c35552 Whoops, one bit too short. 2016-07-09 17:51:46 -04:00
Thomas Harte
cd362b46b3 This is a valid attempt to send a whole byte, I think. 2016-07-09 17:51:04 -04:00
Thomas Harte
3560babd7e Got back to a failing test, now while trying to transmit a whole byte. Good stuff! 2016-07-09 17:39:51 -04:00

66caa3c6dc Fixed setup of bridge class. 2016-07-09 17:23:43 -04:00

bf03985ea4 Here's an instantly failing test... 2016-07-09 17:22:10 -04:00
Thomas Harte
da6fe2e983 This should be enough of a shell to write some actual tests. 2016-07-09 15:47:53 -04:00
Thomas Harte
865eb421cd Quick on-disk tidy up. 2016-07-09 15:44:55 -04:00
Thomas Harte
7cc4bf3fe7 Hit and hope is getting me nowhere. Time to unit test this thing. 2016-07-09 15:40:25 -04:00
Thomas Harte
8827597363 Messier and messier, but I've at least attempted to implement hardware attention acknowledge. 2016-07-08 19:00:39 -04:00
Thomas Harte
9a08ef61cb Still fumbling in the margins: made an effort not to imply that the 1540 is forever reading syncs. 2016-07-07 22:13:18 -04:00
Thomas Harte
199c0e27e0 Mostly just random guesses now, to be honest. It's approaching the end of my window for the morning. 2016-07-07 07:16:36 -04:00
Thomas Harte
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
Thomas Harte
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
Thomas Harte
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

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

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
