Support for APDS9960

[dglaude]

I have an "APDS9960 Proximity, Light, RGB, and Gesture Sensor" and plan to do a minimal support library for Circuit Python (maybe just gesture detection).

This is a place holder to avoid duplicate work if somebody is working on this.
I will update if I make any progress... and if you start working on this, please say it here.

For reference, *Python ressources that can be usefull

Some very old attempt in Micro Python I made a year ago: https://gist.github.com/dglaude/1ab912dd060f22e54aa9dc083b058957

Some GPL code for plain Python found on Github for a simple version of the chip (9930 vs 9960):

Some Python project that failed to use apds9960 because of missing library:

I created a repository for this library: https://github.com/dglaude/adps9960-circuit-python

Cool! Ping me when you want me to look at it. Once its ready I'll fork it into adafruit's repos.

oof we have to issues for this, other one is here!
#411

[dglaude]

I have not started working on the APDS9960 driver for circuit python...
So if anybody feel like doing it, please do.
I'll report here if I find more time and energy for that project.

Some work in progress from @mrmcwethy here: https://github.com/mrmcwethy/Adafruit_CircuitPython_APDS9960

I have completed a candidate library that is written CircuitPython that support gesture, proximity, and color detection. I used the Adafruit_APDS9960 Arduino library as a template for the CP version. This has had some serious testing by @Jerryn and @kattni . Thanks to them. i would like the following project to be reviewed and forked into github.com/adafruit. @tannewt has already given me early feedback and I have made the requested adjustments as a result.

@deanm1278 heya dean, here's the py library to test :)

[tannewt]

I've forked it into the Adafruit repo. Please do a release and add it to the bundle. Thanks!

@ladyada @mrmcwethy @tannewt Tested all examples with circuitpython metro m0 2.1.0, latest bundle 2.1.0, myp-cross 2.1.0
gesture, color, prox interrupt all work very well! Interface is very good any circuitpythony

Dear @mrmcwethy , I tested a little bit on
Adafruit CircuitPython 2.2.0-rc.2 on 2017-12-30; Adafruit Feather M0 Express with samd21g18

Testing involved:

1. Copy the 3 files from https://github.com/mrmcwethy/Adafruit_CircuitPython_APDS9960/tree/master/adafruit_apds9960 into a folder named /Volumes/CIRCUITPY/lib/adafruit_apds9960
2. Copy the 3 examples files gesture.py proximity.py and color.py into /Volumes/CIRCUITPY/
3. Copy each to main.py to test them one by one.

They all fail with MemoryError: memory allocation failed, allocating ### bytes at respectively line 3, 4 and 5.
The offending line is from adafruit_apds9960.apds9960 import APDS9960.

Since @deanm1278 successfully tested, I may I missed one step.
Should I use myp-cross to consume less memory?

[dglaude]

My fault... I had to use mpy-cross-2.2.0-macos-high-sierra to transform init.py apds9960.py colorutility.py into *.mpy file.

Now I can confirm it is working with 2.2.0-rc.2.

The only issue I have is on the non uniform use of pin for interrupt.

Readme.rst suggest to use A1:

int_pin = digitalio.DigitalInOut(A1)

Proximity.py example use A2:

int_pin = digitalio.DigitalInOut(board.A2)

Some cleaning to make Readme and example match in style and pin selection would be welcome.
