Simply Automationized: Raspberry Pi Digital Picture Frame: Part 2 Adding an Accelerometer and some more!

UPDATE (4-17-2015):

To see "Part 1" of this project please go here
So we have few new features!!

Ability to hide/show clock and temperature via phone webapp
Change time between image transitions via webapp
Uploading multiple images from the web interface now works.
Deleting Images now works.
Lazy loading of images when looking through them on the webapp. (loads as you scroll)
I just added a 3-axis sensor to the 7" frame and have it broadcast to the HTML side the angle of rotation.

TODO(Coming Soon)

Weather feed option in the config. (see weather every 10 slides, and or outside temperature in right hand corner)
DNLA Support for those who have NAS servers with millions of images.
Option to only show images of the same aspect ratio as your picture frame rotation.(if you frame is vertical show vertical taken images and visa vera)
piframe image for download so no setup is required (except hardware)

Details on the new webapp features

To make it more handy to have a IoT picture frame I've added some handy configurations that load when the frame starts up.

Details on the Acceleromter

I updated the git repository with a class to communicate via i2c to a MMA7455 accelerometer.
https://github.com/SimplyAutomationized/piframe/blob/master/MMA7455.py
The class has a callback method within it so it can broadcast a tilt change to whomever instantiates the class. Which I'm calling it within the websocket code and broadcasting to the client(the frame) the correct angle.

#I check the config file to see if you have enabled the tilt sensor

if(config['tiltsensor']):
 self.tiltSensor=tilt.TiltSensor(self.rotateFrame)
 self.tiltSensor.start()
#...later in the code we define the callback rotateFrame when rotation changes.

#(when the X axis inverts)
def rotateFrame(self,data):
 rotation=data*270
 self.frameconfig.changeKey('rotation',rotation)
 self.sendNewConfig(self,all=True)
#the code then broadcasts it's new rotation, the CSS on the frame then rotate's the images based off of the new rotation :-) win!
