Quick fixes: the binary tape player now considers talk to the sleep observer only if motor control changes. The Amstrad CPC no longer attempts to use the component argument to identify the caller, since this will often be that of the superclass and not that of the derived class known to the CPC.

Added support for the ID 20 block and fixed a minor error in my skip-the-contents version of block 11: length is three bytes long, not two. This gives me enough structure properly to get to the end of my current test CDT, albeit without making any of the noises.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.

Thomas Harte
75d67ee770
Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.

Clean ups along the Electron::Tape line: ensured that the ClockReceiver is opted into only once, and that its run_for propagates all the way along the chain.

Discovering that there is such a thing as P81 — a ZX81 file without the name omitted — added support for it. Extended FileHolder while I was here to retain the file name and be able to supply its extension, as my quick-fix test-the-last-character approach to o/p/80/81 discrimination stops working with p81 thrown into the mix and this feels like the correct factoring.

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.

Chopped time accumulation out of the default Tape process because it's proving to be sufficiently expensive for a TZX as not to be worthwhile. Introduced a cheaper position capturing/restoring method.

Started sketching out greater support. Mostly TODOs right now, but pulse sequence and pure tone are implemented. I probably also need at least the CSW block to hit everything you might see in a ZX80 or ZX81 tape. Then I can worry about the rest when I have a way to test them.

Thomas Harte
238348c885
Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required.
2017-07-16 21:33:11 -04:00

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.
