Adding another platform

[Gadgetoid]

How would I go about adding PicoSystem as an additional platform to ugame? I started by copying and pasting one of the existing platforms and making some minor tweaks therein, and that seems to work.

However, it looks like there are distinct stage.py files for each platform. Which one is the source of truth?

In my case I'll probably also need to shim out a custom audio engine, since the tiny piezo doesn't quite handle PWM audio and is better driven with a simple single-tone PWM. Is within ugame the right place to do this?

Am I even barking up the right tree?

Edit: I've raised a PR adding DisplayIO to the PicoSystem board in CircuitPython here - adafruit/circuitpython#5398

Hi, this is great, I was planning to port Stage on the PicoSystem myself, as soon as I got my hands on one.

There is only one "real" stage.py at the root of the repository, all the others are just symbolic links to that one file, to make it easier to include it as a frozen library (the directory is then added to the board definition, like this https://github.com/adafruit/circuitpython/blob/main/ports/atmel-samd/boards/pewpew_m4/mpconfigboard.mk#L45).

You can have a DummyAudio in your pygame.py, like here https://github.com/python-ugame/circuitpython-stage/blob/master/itsybitsy_m4_express/ugame.py#L49-L57 if you don't want sound at all. If you want to use audiopwmio after all, then here is an example of that: https://github.com/python-ugame/circuitpython-stage/blob/master/meowbit/ugame.py#L55-L74

If you want to implement your own way of making sounds, that is incompatible with all the other boards that use Stage, I would recommend doing that as a completely separate library, and letting the game author choose (for example, they could then try to import your library, and if that fails, fall back to Stage's audio object).

I haven't seen your displayio pull request before, as I'm on a vacation right now and have worse access to the Internet, I agree that you probably want to use the keypad module instead of gamepad/gamepadshift. You can see the examples of changes required in ugame.py for this here: b014aa0 and here: a895b3a

Let me know if I can help in any way.

I can certainly make that happen sooner rather than later if you want to play.

I completely missed this! And - of course - completely broke it when hacking on a copy of stage.py for picosystem.

I'll look into it! Thank you.

In the mean time, enjoy your vacation!
