||Command:||'''expose'''||
||Contexts:||Network socket, serial console, stage2 only||
||Function:||Take an exposure (integration)||
||Required Parameters:||None.||

=== Usage ===

This command is used after setting up parameters for an exposure.  The last [wiki:GraspSwControllerCmdEtype etype] and [wiki:GraspSwControllerCmdEtime etime] commands used since the controller booted will apply.  For example, a 45 second DARK exposure (no shutter activation) is performed as follows:

{{{
etype dark
etime 45000
expose
}}}

This command is typically preceded by [wiki:GraspSwControllerCmdClean clean] and followed by [wiki:GraspSwControllerCmdReadout readout].
