function RPI_sn3218Setup(pinBase)
// Function for setting up SN3218 I2C based LED controller.
//
// Calling Sequence
//  RPI_sn3218Setup(pinBase)
//
// Parameters
//  pinBase: any number above 64. The consecutive 18 pins will be allocated alongwith.
//
// Description
//  This function sets up the extension module for the SN3218 I2C based LED controller.There is no I2C device address passed into the setup function – the SN3218 has a fixed I2C address of 0x54, so there’s no need to refer to it other than internally inside the driver. This also means that only one device can be connected to a Raspberry Pi.
