Thomas Harte	9d953421d8	After a quick check, added a couple of other _delegate initialisations. I should probably find a way to template this.	2017-08-01 07:07:43 -04:00

Thomas Harte	313b36944f	Ensured that the final bit of a tape isn't dropped even if the tape ends exactly after it, by not posting a false pulse, being less restrictive about what can cap a bit, and in any case using a long gap as the end-of-file bookend.	2017-07-22 15:41:33 -04:00
Thomas Harte	456fdda6c2	Ensured that the mark_end step can't overwrite another recognised symbol.	2017-07-22 15:40:22 -04:00
Thomas Harte	06ea81fdb2	Made sure that unrecognised waves don't block the symbol queue, and allowed any type of nonsense to be skipped before finding a byte.	2017-07-21 20:23:26 -04:00
Thomas Harte	d69b1e2d11	Switched parsing logic to looking only for upward zero crossings, that being my new understanding of the ROM.	2017-07-21 19:39:38 -04:00
Thomas Harte	130d598ec9	Corrected some minor out-of-style breaks, and ensured that the name of ZX81 files is returned.	2017-07-17 19:52:54 -04:00
Thomas Harte	2179edc7fe	Adjusted to allow the very first thing found to be data, and ensured that unrecognised symbols break files just as gaps do.	2017-07-17 07:43:47 -04:00
Thomas Harte	c2bc34fd87	Eliminated the PLLParser class. I think the proper abstraction if and when another machine requires PLL-esque parsing is probably to template out the Acorn wiring of a PLL to a Parser, and/or generalise the Acorn shifter. It'll be easier to decide when the time comes.	2017-07-16 19:25:26 -04:00
Thomas Harte	1d3ae31755	Abstracted the concept of an Acorn shifter away from being a PLLParser. The Acorn tape parser now skips using that class and uses the shifter. The actual Electron also uses the shifter. So the two are completely aligned. Net result: the Electron should successfully load exactly when static analysis was successful.	2017-07-16 19:24:01 -04:00
Thomas Harte	e5188a60dc	Settled on the new average-of-length approach to a PLL window sizing, eliminating the old errors-of-phase approach. Since it anchors automatically to the original target clocks per bit, killed the explicit mention of a tolerance.	2017-07-16 19:03:50 -04:00
Thomas Harte	e71d13c090	With the new PLL implementation, switching to a deeper window size returns the Acorn tape parser to: working.	2017-07-16 17:12:12 -04:00
Thomas Harte	c8575fe6e0	Mild clean ups, and a tweak to permitted top and bottom phase.	2017-07-16 13:39:08 -04:00
Thomas Harte	253f9603ed	Split the normal tape parser class into two in order to add a new option: a PLL-driven tape parser. Decided to see what happens if I attempt to use that to parse CSW Acorn data.	2017-07-15 19:07:35 -04:00
Thomas Harte	648618d280	Tweaked bit timing decision.	2017-07-13 21:26:05 -04:00
Thomas Harte	2f42874fd3	Another fix to deal with real-time fighting: allow 8 and 18 pulses to be recognised as 1s and 0s. That's because the hand-off from ROM routines to parsing may occur very shortly before the first pulse of a valid sequence, making it look like there's a ghost. A cleaner solution needs to be found, probably revolving around allowing parsers to be attached to tapes and therefore to run constantly.	2017-07-06 22:33:03 -04:00
Thomas Harte	919fc48cc5	Fixed dumb out-of-bounds access error.	2017-06-22 22:28:50 -04:00
Thomas Harte	2c6414ce11	Adjusted to allow inspect_waves to swallow a gap before a bit if necessary, increasing the opportunities for its call.	2017-06-11 18:31:09 -04:00
Thomas Harte	b07af2660d	Adjusted to make sure that the very end of a tape is properly measured.	2017-06-08 21:33:35 -04:00
Thomas Harte	bc0d70b2f7	Added: a shout-out when the tape has been exhausted.	2017-06-08 21:32:27 -04:00
Thomas Harte	7e10c7f9d8	Relocated the ZX80/81 concept of a 'file' out from Tape into Data, given that it's an exact duplicate of memory.	2017-06-08 19:09:51 -04:00
Thomas Harte	c47128f433	Widened tolerances and ensured zero bits aren't prematurely discarded.	2017-06-07 17:50:03 -04:00
Thomas Harte	dbd2944c13	Took an initial run at the ZX80/81 parser.	2017-06-07 17:27:05 -04:00
Thomas Harte	4603fa6f24	Extended explicitly to support a token of lookahead, which is pretty much what was on offer anyway. Also corrected instance variable names, as per better adoption of C++ norms.	2017-06-07 17:21:57 -04:00
Thomas Harte	60300851ea	Started sketching out a tape parser for ZX80 and '81 files. I think this'll help me to verify whether the .O input is working.	2017-06-07 10:12:13 -04:00
