Libraries-Drivers Hardware Android 5.1.1

Hi, I´m working with Dragon Board 410c and I´m trying to interface some devices such camera, headset, sensors and a projector (display).

I´m looking for libraries and drivers that allows me to change and control the paramaters of all of these things. I do not know exactly what kind of libraries or drivers I have to use.

Can anybody help me with it? Any guides or current references to work with it will be helpful too.

Thank you in advance.

As a comment, the camera I´m using has an UART communication protocol and the projector (DLP LightCrafter 2010EVM) has a different resolution (lower) than Android already has.

As far as sensors, please refer to the porting guide here: https://developer.qualcomm.com/download/db410c/sensors-porting-guide-dragonboard-410c.pdf
