* This driver is a modified version of the IO_DFPlayer.h file
* *********************************************************************************************
*
* 2023, Added NXP SC16IS752 I2C Dual UART to enable the DFPlayer connection over the I2C bus
* Dec 2023, Added NXP SC16IS752 I2C Dual UART to enable the DFPlayer connection over the I2C bus
* The SC16IS752 has 64 bytes TX & RX FIFO buffer
* First version without interrupts from I2C UART and only RX/TX are used, interrupts may not be
* needed as the RX Fifo holds the reply
*
* Jan 2024, Issue with using both UARTs simultaniously, the secod uart seems to work but the first transmit
* corrupt data. This need more analysis and experimenatation.
* Will push this driver to the dev branch with the uart fixed to 0
* Both SC16IS750 (single uart) and SC16IS752 (dual uart, but only uart 0 is enable)
*
* myHall.cpp configuration syntax:
*
* I2CDFPlayer::create(1st vPin, vPins, I2C address, UART ch, AM);
* 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 (only 1 vPin is supported)
* I2C Address : I2C address of the serial controller, in 0x format,
* UART ch : Indicating UART 0 or UART 1, values 0 or 1
* AM : audio mixer, values: 1 or 2 to select an audio amplifier, no effect if AM is not installed
* vPins : Total number of virtual pins allocated (2 vPins are supported, one for each UART)
* 1st vPin for UART 0, 2nd for UART 1
* I2C Address : I2C address of the serial controller, in 0x format
* xtal : 0 for 1,8432Mhz, 1 for 14,7456Mhz
*
* The vPin is also an pin that can be read, it indicated if the DFPlayer has finished playing a track
