/*
|
||||
* 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 allows the device to be controlled through IODevice::write() and
|
||||
* IODevice::writeAnalogue() calls.
|
||||
*
|
||||
* The driver is configured as follows:
|
||||
*
|
||||
* DFPlayer::create(firstVpin, nPins, Serialn);
|
||||
*
|
||||
* Where firstVpin is the first vpin reserved for reading the device,
|
||||
* nPins is the number of pins to be allocated (max 5)
|
||||
* and Serialn is the name of the Serial port connected to the DFPlayer (e.g. Serial1).
|
||||
*
|
||||
* Example:
|
||||
* In halSetup function within myHal.cpp:
|
||||
* DFPlayer::create(3500, 5, Serial1);
|
||||
* or in myAutomation.h:
|
||||
* HAL(DFPlayer, 3500, 5, Serial1)
|
||||
*
|
||||
* Writing an analogue value 1-2999 to the first pin (3500) will play the numbered file from the
|
||||
* SD card; e.g. a value of 1 will play the first file, 2 for the second file etc.
|
||||
* Writing an analogue value 0 to the first pin (3500) will stop the file playing;
|
||||
* Writing an analogue value 0-30 to the second pin (3501) will set the volume;
|
||||
* Writing a digital value of 1 to a pin will play the file corresponding to that pin, e.g.
|
||||
the first file will be played by setting pin 3500, the second by setting pin 3501 etc.;
|
||||
* Writing a digital value of 0 to any pin will stop the player;
|
||||
* Reading a digital value from any pin will return true(1) if the player is playing, false(0) otherwise.
|
||||
*
|
||||
* From EX-RAIL, the following commands may be used:
|
||||
* SET(3500) -- starts playing the first file (file 1) on the SD card
|
||||
* SET(3501) -- starts playing the second file (file 2) on the SD card
|
||||
* etc.
|
||||
* RESET(3500) -- stops all playing on the player
|
||||
* WAITFOR(3500) -- wait for the file currently being played by the player to complete
|
||||
* SERVO(3500,2,Instant) -- plays file 2 at current volume
|
||||
* SERVO(3501,20,Instant) -- Sets the volume to 20
|
||||
*
|
||||
* NB The DFPlayer's serial lines are not 5V safe, so connecting the Arduino TX directly
|
||||
* to the DFPlayer's RX terminal will cause lots of noise over the speaker, or worse.
|
||||
* A 1k resistor in series with the module's RX terminal will alleviate this.
|
||||
*
|
||||
* Files on the SD card are numbered according to their order in the directory on the
|
||||
* card (as listed by the DIR command in Windows). This may not match the order of the files
|
||||
* as displayed by Windows File Manager, which sorts the file names. It is suggested that
|
||||
* files be copied into an empty SDcard in the desired order, one at a time.
|
||||
*
|
||||
* The driver now polls the device for its current status every second. Should the device
|
||||
* fail to respond it will be marked off-line and its busy indicator cleared, to avoid
|
||||
* lock-ups in automation scripts that are executing for a WAITFOR().
|
||||
*
|
||||
* *********************************************************************************************
|
||||
* 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
