This is a fork of the Sunsaver interface software created by Tom Rinehart
Updated by ken restivo to add a Makefile and some other minor modifications.
I had to use libmodbus 2.0.3 because 3.02 suggested in the original blogpost did not compile properly on my system.
This fork requires a forked branch of libmodbus which supports half-duplex operation.
As the original author mentioned in his blog post, you'll also need a build system for linux or OSX.
I built and run libmodbus and this software successfully on a Beaglebone running Angstrom linux, and on Debian Linux on X86-64, i386, and ARMEL.
You'll also need a SunSaver MPPT and a MSC interface or equivalent.
Have fun!
