Sparki-learning

The primary changes to this release which are visible to users are related to retry logic. Over the years, OSes appear to be more aggressive with energy saving. This causes the connection to sparki to timeout on a regular basis. Rather than report the error to the user, it's better to retry the connection to see if it was just a power saving issue.

This release places constants into their own constants.py file.

GUI functions have been modified to use pySimpleGUI, and gui functions which are not specific to sparki have been moved into their own gui.py file.

I have abandoned the use of the standard logging module. It never worked quite how I wanted it to.

I believe that no code that relies on the library will need to be changed, unless it relied on the fact that we previously used logging.

The sparki_myro library which runs on the sparki itself now contains new setup code which will (I hope) fix ultrasonic sensors which aren't working properly.

I have broken out a variety of utility functions into a util library. This is in preparation of ultimately making the library object oriented.

The LCDdrawLine() command in the underlying sparkiduino library was buggy. I have reimplemented it in Python and removed the code from sparki_myro.c

The sparki.systemVoltage() command in the sparkiduino library was unreliable per ArcBotics. I have depricated it -- it will always return -1.

This release cleans up the source code some, and adds the syncWait() command to make synchronized movement across multiple computers with multiple sparkis a little easier

This version updates the library to work with Python 3.6 (the most recent version as of this date), and adds the noop command.

Macs continue to be problematic in the sense that they drop the bluetooth connection very quickly, and the library has to compensate behind the scenes to restore that connection. This release adds a noop command and a noopWait to continue to send packets to keep the connection alive.
