Serial Wombat Arduino Library

Video Tutorial

A video is available for Getting Started with the Serial Wombat 4B using I2C:


This library is designed for use with the Arduio platform.
The SerialWombat class is the basis for all sketches. Include SerialWombat.h to access all Serial Wombat classes.

One Serial Wombat instance should be declared for each Serial Wombat attached to the host. This is typically done by declaring it globally:

SerialWombat sw;

Once the Serial Wombat is declared, it must be initialized using the SerialWombat.begin() method. There are separate begin methods for I2C (Wire) and Uart (Serial):



sw.begin(Wire, 0x6C);  //I2C initialization with address 6C

Presense of a Serial wombat can be determined by testing the return value of the SerialWombat.queryVersion() method:

if (sw.queryVersion())
    //Serial Wombat detected.
    //Serial Wombat not detected.

Pin Modes

Most Serial Wombat functionality is achieved through Pin Modes. Most pin modes are achieved by declaring an instance of a class for that pin mode with the Serial Wombat instance that pin mode will be attached to as a parameter. A .begin call with additional parameters is typically called during the Arduino setup() function.

The following Pin Modes are avaialble on all 4 pins of the Serial Wombat 4B:

The following Pin Modes are avaialble on pins 1,2,3 of the Serial Wombat 4B and all 4 pins of the Serial Wombat 4A:

Due to hardware initializations unexpected side effects may occur if the same pin is configured multiple times to different pin modes after Serial Wombat initialization

Additional Capabilities:

The Serial Wombat can measure its own source voltage with the SerialWombat.readSupplyVoltage_mV method.

The Serial Wombat can report its Model and Firmware revision with the SerialWombat.queryVersion method.
