5 Software Drivers

This solution supports control through I2C bus.

Linux drivers for the LP875x-Q1 and LP8732-Q1 are available in public git repository. These can be used to help integrate the LP875x-Q1 / LP8732-Q1 control to system software:

LP8756x-Q1

LP8732-Q1

Note: Every header file is in the include folder starting from the root directory. So once in include folder, the user can navigate to the relevant header file. For example, the LP87565.h file: https://github.com/torvalds/linux/blob/master/include/linux/mfd/lp87565.h.
