wasp-os: MicroPython for PineTime!

[danielt]

To be honest I've never seen the simulator unreactive to these things. There are a couple of ways a broken application could cause this but you've done a fresh clone and the built-in applications are unlikely to cause this.

Either way I'd recommend starting by adding a couple of prints:

1. Check the lowest level of the simulator is correctly handling events by printing event here: https://github.com/daniel-thompson/wasp-...ay.py#L221
2. Check wasp-os is handling interrupts from the (simulated) touch screen by printing dbuf here: https://github.com/daniel-thompson/wasp-...ay.py#L105

After that follow where the prints lead and add further prints further through the stack to zoom in. If you need to learn more about the structure of wasp-os you might be able to use traceback.print_tb or pdb.set_trace from critical bits of code (the former prints a stack trace, the later enters a text mode debugger allowing you to explore dynamically)... or you can just ask here once you have gathered more evidence!

1. Gives back <sdl2.events.SDL_Event object at 0x.....
2. Gives back bytearray(b'\x03\...

Now, I realized that the simulator seems to be working -- it tells me "volume down" (for the mock music app), for example -- but not updating the simulator display (the time does not change either, for example). I'm a bit overwhelmed by deciding where to look next. What I've been doing is removing the dependencies of the simulator (requirements.txt) via pip and installing them via my distro's package manager, which my distro's wiki says is the preferred way to install python packages. The point being, this looks like a sdl-related problem if I understand correctly, and well, I have very little experience with that. Oh and the simulator's stdout tells that it does in fact refresh (I put a print there), and a lot so. What would you do next? Thanks for the advice so far!

A simple trick might be to reverse the comments in lines 57/58: https://github.com/daniel-thompson/wasp-...lay.py#L58

Using sdl2.ext.PixelView instead of sdl2.ext.pixels2d makes screen updates incredibly slow but there is a warning issued by pixels2d to say it is experimental so it is worth a try.

Might also be useful to know what distro you are running.
