Thomas Harte	015cea494d	Switched to a much-more straightforward PLL. I think I'm just fiddling now rather than moving forwards. Probably time to move on?	2016-07-28 11:32:14 -04:00
Thomas Harte	e061e849d4	Had a second bash at the PLL. Probably I should read some of the literature.	2016-07-27 16:24:24 -04:00
Thomas Harte	74817f6664	With a history of three pulses, this can track up a 10% sine variation in a 1010101 stream. So I guess this'll do for now?	2016-07-14 19:54:48 -04:00
Thomas Harte	ac1bc588dd	Improved factoring and increased window of testing, causing both the fast and slow tests to show framing errors.	2016-07-14 07:12:02 -04:00
Thomas Harte	d1fe07f14d	Added test of perfect DPLL input timing.	2016-07-12 21:42:23 -04:00
Thomas Harte	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
Thomas Harte	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
Thomas Harte	66caa3c6dc	Fixed setup of bridge class.	2016-07-09 17:23:43 -04:00
Thomas Harte	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	b322baff2f	Added CLI/SEI pair test.	2016-06-29 19:42:39 -04:00
Thomas Harte	db7c6430b5	Fixed Klaus Dormann termination condition.	2016-06-29 19:16:34 -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
Thomas Harte	d5e50f5ea0	Got a bit more explicit about how ports are identified on the 6522.	2016-06-26 12:30:01 -04:00
Thomas Harte	25a5455d33	Completed bridge interface.	2016-06-20 21:07:01 -04:00
Thomas Harte	fe17d1778c	Expanded 6532 tests substantially, beefing up implementation to match.	2016-06-20 21:02:42 -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	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	9b64f64db7	Attempted to normalise some style decisions.`	2016-04-24 22:32:24 -04:00
Thomas Harte	675070c5dd	Very, _very_ minor: switched to normal C++ constructor syntax for simple variable initialisation.	2015-12-06 16:53:37 -05:00
Thomas Harte	cc98534f94	Added test for NOP, discovering the undocumented ones to be the incorrect length.	2015-08-13 07:32:50 +01:00
Thomas Harte	6616265d93	Fixed collision tests, added a few more timing tests.	2015-08-13 03:33:45 +01:00
Thomas Harte	dd0f17130a	Found and fixed some timing errors in absolute indexed and in (indirect), y addressing modes: neither is able in write or read-modify-write modes to shave a cycle as then can when reading.	2015-08-13 02:58:39 +01:00
Thomas Harte	975836c30f	Added a quick snippet test, discovering that I've cut a cycle from read/modify/writes.	2015-08-13 02:18:41 +01:00
Thomas Harte	503d684af0	Added a couple of timing tests, both of which seem to pass for now.	2015-08-13 01:55:23 +01:00
Thomas Harte	e8f70398c1	Added one basic timing test, for now: implied nop should be two cycles.	2015-08-13 01:06:56 +01:00
Thomas Harte	d19f8ed507	Removed the implicit reset upon 6502 startup, adding a reset line. Hence all tests now pass again. Added an empty shell for timing tests, the all-RAM 6502 now counting bus cycles.	2015-08-13 00:51:06 +01:00
Thomas Harte	53dd5c8f16	Trying to fix my RDY line emulation. Switched to PAL timings, at least temporarily, since it's starting to make a difference.	2015-07-31 16:44:53 -04:00
Thomas Harte	20c2d98b9a	Converted remaining spaces to real tabs.	2015-07-30 20:51:32 -04:00
Thomas Harte	6252f6030f	Switched to idiomatic source name, ensured latest project name is in all appropriate header places, threw texture coordinates slightly into the shader mix.	2015-07-26 15:25:11 -04:00
Thomas Harte	5160b6bbb8	Separated out different test suites into different XCTest subclasses.	2015-07-16 20:52:16 -04:00
Thomas Harte	24c0579b94	Shuffled things and guessed at things until the Xcode project was happy being subservient to the project proper.	2015-07-16 20:27:31 -04:00
