OSGi Services

Method documentation for all OSGi services (from BUG and from other users) is available in the javadocs. The services listed below can be found in the com.buglabs.bug.module.lcd.pub package in the latest revision of the BUG javadocs. Each service is an interface with its own methods.

From com.buglabs.bug.module.lcd.pub:

• ILCDModuleControl – Service for basic module controls & interaction with base (extends IModuleControl and IModuleLEDController)
• IModuleDisplay – Service for GUI widgets & display control

Through com.buglabs.bug.module.lcd.accelerometer classes:

• IAccelerometerRawFeed – Service that provides raw data from the accelerometer
• IAccelerometerSampleFeed – Service for reading continuous samples from the accelerometer
• IAccelerometerSampleProvider – Service for reading a single sample from the accelerometer

Web Services

When a BUGview module is attached, the Acceleration web service becomes available, providing acceleration along 3 axes.
