Hi,
I have checked the code of the driver you provide, and I see some updates are needed in the driver itself as it doesn't support raspberry pi 2
I can do this for you : Fix the compilation to work with raspberry pi 2;
Validating the functioning of the driver is out of the scope of my bid;( I didn't go into much details of the driver when I checked it, I just checked the compiling steps and how they are done)
If you want to work on that too, I will add cost and time to my bid to cover that.
I suggest we do the compilation fix first, then you try it, if it doesn't work from scratch correctly, which means some deeper fixes in the driver algorithm is needed, then we can do a second project.
Contact me back if interested.
Cheers
