Explaining how to build the code is on my todo list and will be on the main site.
It's not straightforward.
If you want to try :
You need a Linux machine and to compile libmaple first.
Take the libmaple 0.0.11 also from gibhub:
https://github.com/leaflabs/libmaple/Rename limaple directory to "libmaple".
and follow the instructions here :
http://leaflabs.com/docs/index.htmlGo ahead untill you can compile it with the ARM cross compiler.
Once this is done, you made the most difficult part.
Take the PreenFM sources from github
https://github.com/ixox/preenPut the preenFM tree at the same level as the "libmaple" directory.
Go in the PreenFM tree, then "make" then "make install".
