Failing to use / import apigpio

From missionpinball/mpf#1427

File "/usr/local/lib/python3.7/dist-packages/mpf/core/machine.py", line 212, in initialise
    yield from self.initialise_core_and_hardware()
  File "/usr/local/lib/python3.7/dist-packages/mpf/core/machine.py", line 197, in initialise_core_and_hardware

    m = __import__(module)

    import apigpio
  File "/usr/local/lib/python3.7/dist-packages/apigpio/__init__.py", line 2, in <module>
    from .apigpio import Pi

I then go on to try to import apigpio from python2 and python3 and get :

Seeing from .apigpio import Pi I was looking for a Pi.py in /usr/local/lib/python3.7/dist-packages/apigpio/ but couldn't fit it :

ls /usr/local/lib/python3.7/dist-packages/apigpio/
__init__.py  __pycache__  apigpio.py  ctes.py  utils.py
ls /usr/local/lib/python2.7/dist-packages/apigpio/
__init__.py  __init__.pyc  apigpio.py  ctes.py  ctes.pyc  utils.py  utils.pyc

async and await are now reserved keywords in Python 3.7: https://docs.python.org/3/whatsnew/3.7.html#summary-release-highlights. Afaik asyncio.ensure_future is the new method to use (does not work in early 3.4 but that is EOL anyway).

The PR does not work for me.

https://github.com/jabdoa2/apigpio/blob/patch-1/apigpio/apigpio.py#L475

self._loop.sock_sendall(self.s, data) is a coroutine, see:

https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.loop.sock_sendall

It needs a yield from.

My gpio_test.py had the content of https://github.com/PierreRust/apigpio/blob/master/samples/gpio_write.py

We moved to a different repository for our fork: https://github.com/missionpinball/apigpio

We also publish it as apigpio-mpf

Will look into your comment to see if it also affects that repo.

@NNTin have a look at our maintained fork: https://github.com/missionpinball/apigpio. We also ship that to pypi: https://pypi.org/project/apigpio-mpf/
