- BYTE Index
Range: 0-3 / 0=Command, 1=Feedback, 2=Data MSB, 3=Data LSB 
- BYTE Return


Initialise

Initialise
Sets up the UART and does some housekeeping. Must be called before calling any of the other component macros. 
- VOID Return


IsPlaying

IsPlaying
Checks to see if the last played track is still playing 
- BOOL Return


IsReplyAvailable

IsReplyAvailable
Checks to see if new data has been received from the module. Returns true when new data is available. Collect the data using the GetReplyByte macro.

- UINT Mode
0=Pause, 1=Play, 2=Reset, 3=Stop 
- VOID Return


PlayTrack

PlayTrack
Plays track from the selected folder. MP3 & Advert folder track numbers should be 4 characters long e.g. 0001 any name.mp3, Other folder track numbers should be 3 characters long e.g. 001 Any name.mp3, Root the Track played in placement order. 
- BYTE Directory
0=Root, 1=Folder "01" - 99=Folder "99", 100=MP3, 101=Advert 
- UINT Track
Track number 1="001*.MP3" / "0001*.MP3", 100="100*.MP3" / "0100*.MP3" 
- VOID Return


SendCommand

SendCommand
Sends a command to the DFPlayer module 
- BYTE Command
Command code byte

- VOID Return


SetVolume

SetVolume
Sets the volume level for the module 
- BYTE Volume
Range: 0 (min) - 30 (max) 
- VOID Return


SkipTrack

SkipTrack
Jump to the next or previous track 
- BOOL Direction
0=Next, 1=Previous

- UINT Timeout
Number of milliseconds to wait, 0=WaitForever 
- BOOL Return


Property reference

Properties
Connections
Channel
UART Channel selector Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels. Hardware channels use the selected peripheral on-board the target microcontroller. 
Baud Options
Baud rate option selector 
Baud Rate
 
TX
Pin to be used for Transmit data 
RX
Pin to be used for Receive data 
Use Busy Pin
Controls if we are monitoring the busy pin or not. Used by the IfBusy component macro. 
Simulation
Scope Traces
Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD. 
Console Data
Selects if the console data is automatically generated or not 
Console Format
Controls if the data is shown as a log with time and date stamps or just as raw data 
Console Columns
Number of characters that can be displayed on a single line of the console. 
Data Source
