*
* Dec 2023, Added NXP SC16IS752 I2C Dual UART
* 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:
*
* I2CRailcom::create(1st vPin, vPins, I2C address);
*
* myAutomation configuration
* HAL(I2CRailcom, 1st vPin, vPins, I2C address)
* 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 (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
