This module enables MicroPython-based projects to use the DFPlayer Mini via simple function calls.
It only supports SD-Card playback and operates in tranmit only mode.
First import the SimpleDFPlayerMini module from dfplayer.py
from dfplayer import SimpleDFPlayerMini
Then create an instance of SimpleDFPlayerMini
player = SimpleDFPlayerMini(1, 0, 1)
Arguments for the constructor consist of the following parameters:
- The UART-id
- Initial volume
- Initial playback mode
The above constructor initializes a SimpleDFPlayerMini object with UART-id 1, an initial volume of 0 and the folder repeat playback mode.
As a example for the ESP8266 this means UART1 is used which supports TX-only communication via GPIO2. This may differ from board to board so take a look at this.
The function calls are self-explanatory for the most cases. If not take a look at the wiki.
Basically you only have to connect the RX of the DFPlayerMini to the specific TX port of your board. Continuing our example from before RX from the DFPlayerMini goes to GPIO2 on the ESP8266.
Also solder a 1k resistor inbetween the connection or professionally speaking in serial.
No other Pins (except VCC and GND) should be used.
