// Play mp3 files from a Micro-SD card, using a DFPlayer MP3 Module on a SC16IS750/SC16IS752 I2C UART
//=======================================================================
// DFPlayer via NXP SC16IS752 I2C Dual UART. Each device has 2 UARTs on a single I2C address
// Total nr of devices on an I2C bus is 16, with 2 UARTs on each address making a total of 32 UARTs per I2C bus
// I2C address range 0x48 - 0x57
//
// audioMixer can be 1 when connected to audio mixer 1, 2 when connected to audio mixer 2, 0 will default to 1
// Generic format:
// I2CDFPlayer::create(1st vPin, vPins, I2C address, xtal);
// Parameters:
// 1st vPin : First virtual pin that EX-Rail can control to play a sound, use PLAYSOUND command (alias of ANOUT)
// vPins : Total number of virtual pins allocated (1 vPin is supported currently)
// 1st vPin for UART 0
// I2C Address : I2C address of the serial controller, in 0x format
// xtal : 0 for 1.8432Mhz, 1 for 14.7456Mhz
//
// The vPin is also a pin that can be read with the WAITFOR(vPin) command indicating if the DFPlayer has finished playing a track
