Class CanOpenMG550P

java.lang.Object

org.lsst.ccs.subsystems.fcs.drivers.CanOpenDevice

All Implemented Interfaces:

org.lsst.ccs.framework.HasLifecycle, AlertRaiser, NamedComponent, PieceOfHardware, EmergencyMessageListener

public class CanOpenMG550P
extends CanOpenDevice

A class for carousel accelerometer. Each PDO includes a 16-bit trigger * counter (unsigned), followed by three 16-bit (signed) pieces of data. For the first PDO, this is the angular velocity along the three axes, with a conversion factor of 0.008 dps/LSB. The second PDO encodes the acceleration along the three axes (gravity if there is no movement), with a conversion factor of 0.2 mG/LSB.
