- Download: http://sparks.gogo.co.nz/GD5800_Serial.zip
- Open the Arduino IDE (1.0.5)
- Select the menu item Sketch > Import Library > Add Library
- Choose to install the GD5800_Serial.zip file you downloaded
- Now you can choose File > Examples > GD5800_Serial > HelloWorld
There are two varients of the GD5800 module as shown.
To use this library with a 5v Arduino, connect as follows.
| GD5800 Module | Arduino |
|---|---|
| RX | through a 1K Resistor then to pin 9 |
| TX | pin 8 |
| GND (any of) | GND |
| VCC (any of) | VCC |
To use this library with a 3v3 Arduino, connect as follows...
| GD5800 Module | Arduino |
|---|---|
| RX | pin 9 |
| TX | pin 8 |
| GND (any of) | GND |
| VCC (any of) | VCC |
You can use pins other than 9 and 8 if you wish, simply set them in your code.
If using the on-board speaker driver, then naturally the power demands are significant, and your USB power may not be sufficient at more 1/3rd level of volume or so, the symptom is the audo breaking up and potentially resetting when volume increases.
You should use either an external power source, an external amp, or a lower volume if you experience this problem.
