I did a port of my previous library for the TLV5620 to the MSPhere framework, including the demo. This is classified as an "auxiliary library" since it depends upon the core framework, yet is a bit too specific to be included with it.
Anyways, you can get it at the MSPhere website.
Development on the main library and documentation is coming. I am currently busy with classes, but I have some free time this week. I will use that to update the documentation on the wiki.
Thanks for reading!
