This implements the proposal discussed in the re-opened #279 to add a
pin_factory argument at the device level and remove the ability to
specify a pin instance to device constructors (they now only accept a
pin specification).
Note: there's still a couple of bits to tidy up (tests on "real" Pis,
and pin_factory.release_all needs refinement) but the test suite is now
at least capable of passing on a PC.
Permit replacement of pin_factory without closing old factory. However,
continue closing devices associated with extant pin factory at script
termination.
The real pin tests were broken by the new factory stuff. This commit
fixes them up, and fixes up a few other bits besides (like why the
pigpio PWM tests were failing, why RPi.GPIO sometimes segfaulted on PWM
tests, etc.)
It also causes the real pin tests to run against MockPin (thanks to
@lurch for the suggestion!). This required some tweaks to MockPin to
make it emulate physically pulled up pins itself (which in turn
necessitated changing quite a few pin numbers in the main test suite
because we were using 2 and 3 everywhere), and to allow one MockPin to
drive another. Anyway, everything's working now including all the tests
on a Pi (haven't tried RPIO yet, but only because I'm on a Pi3 -
everything else works with overall coverage of 88% :).
Sorry! Dave's messing around with the pin implementations again.
Hopefully the last time. The pin_factory is now really a factory object
which can be asked to produce individual pins or pin-based interfaces
like SPI (which can be supported properly via pigpio).
Added SPI tests, simplified the shared SPI software bus implementation,
and fixed several protocol errors in our MCP3xxx classes (the x2 and x1
protocols were wrong)
Overhaul the pi_info system:
Pin factories are now capable of generating pi_info themselves (although
currently they all just look up the revision and call pi_info with a
specific one).
PiGPIOPin will now return pi_info for the remote pi which can be
specified by parameter or implicitly by the environment vars.
Overvolted Pis should work properly no matter what (some argument over
whether the revision 7 or 8 chars in this case; both should work). Added
some minor tweaks for the new camera-capable Pi Zero
Finally, added a bunch of tests for pins.data
While the tests work well on a PC or Travis, the Pi (where I ought to be
running them!) has some issues with the timing tests. Need to relax the
tolerance of the "assert_states_and_times" method to 0.05 seconds
otherwise it periodically fails even on something reasonably quick like
a Pi 2 (less failures on a Pi 3 but still occasionally).
Also reduced default fps to 25; if the default timing occasionally fails
on a Pi 2 it's evidently too fast for a Pi 1 and shouldn't be the
default; 25 also doesn't look any different to me on a pulsing LED.
There's also a bunch of miscellaneous fixes in here; last minute typos
and chart re-gens for the 1.2 release.
Change MockPin (and MockPWMPin) to make them behave more like 'real' pins - fixes#206
Add new MockPin tests, and rework some of the existing ones
