microstacknode 0.4.2

The Microstack node functions module.

microstack-node
================
Common functions for interacting with Microstack node boards (Accelerometer,
GPS, etc).

Documentation
=============
[http://microstack-iot.github.io/](http://microstack-iot.github.io/)

You can also find the documentation installed at:

/usr/share/doc/python3-microstacknode/

Install
=======
Make sure you are using the lastest version of Raspbian:

$ sudo apt-get update
$ sudo apt-get upgrade

Install `microstacknode` for Python 3 with the following command:

$ sudo apt-get install python3-microstacknode


Enable Serial Port on Raspberry Pi for GPS
==========================================
1. Disable serial port login
Comment out `T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100` in
`/etc/inittab`

2. Disable bootup info. Remove references to `ttyAMA0` in `/boot/cmdline.txt`.

That is, change from:

dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p6 rootfstype=ext4 elevator=deadline rootwait

to:

dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p6 rootfstype=ext4 elevator=deadline rootwait

3. Reboot.


Controlling the on board OK LED (Raspberry Pi)
==============================================

# disable mmc0 for led
echo none >/sys/class/leds/led0/trigger

# enable mmc0 for led
echo mmc0 >/sys/class/leds/led0

# turn on led
echo 1 >/sys/class/leds/led0

# turn off led
echo 0 >/sys/class/leds/led0
Change Log
==========

v0.4.0
------
- mma8452 accelerometer now returns dictionary for xyz instead of tuple.
This was confusing as it's unexpected for a method to return three values.
*Explicit is better than implicit.*
- Improved docs -- uploaded to readthedocs.

v0.3.0
------
- Fixed mma8452 accelerometer bug. `get_xyz()` now returns values in Gs no
matter what the range is set as. That is, set the range to be 8G and the
`get_xyz()` will return 1 is the accelerometer is only experiencing 1G.
- Changed mma8452 register implementation.
- Added mma8452 SI units method.

v0.2.0
------
- Moved internal hardware drivers to hardware directory.
- Added display and humidity/temperature sensor drivers.
- Added examples for drivers.
- NOT updated HTML docs for new changes. This will be done in the next
update.

v0.1.1
------
- Changed docs for new install instructions (altered name) and also
changed default address for accelerometer.

v0.1.0
------
- Inital structure.
