Added support for DFPLayer over I2c - IO_I2CDFPlayerh
Added IO_I2CDFPlayer.h to support DFPLayer over I2C connected to NXP SC16IS750/SC16IS752 (currently only single UART for SC16IS752) Added enhanced IO_I2CDFPLayer enum commands to EXRAIL2.h Added PLAYSOUND alias of ANOUT to EXRAILMacros.h EXRail additions as per advice from Chris

* DFPlayer is an MP3 player module with an SD card holder. It also has an integrated
|
||||||
|
* amplifier, so it only needs a power supply and a speaker.
|
||||||
|
* This driver is a modified version of the IO_DFPlayer.h file
|
||||||
|
* *********************************************************************************************
|
||||||
|
*
|
||||||
|
* 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, 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 (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 a pin that can be read, it indicate if the DFPlayer has finished playing a track
