Member Function Documentation

AddToDASequence()

virtual int MM::SignalIO::AddToDASequence ( double  voltage )

pure virtual

Adds a new data point (voltage) to the sequence The data point can either be added to a representation of the sequence in the adapter, or it can be directly written to the device

Returns

errorcode (DEVICE_OK if no error)

ClearDASequence()

virtual int MM::SignalIO::ClearDASequence ( )

pure virtual

Clears the DA sequence from the device and the adapter. If this functions is not called in between running two sequences, it is expected that the same sequence will run twice. To upload a new sequence, first call this functions, then call AddToDASequence(double voltage) as often as needed.

Returns

errorcode (DEVICE_OK if no error)

GetDASequenceMaxLength()

virtual int MM::SignalIO::GetDASequenceMaxLength ( long &  nrEvents ) const

pure virtual

Returns the maximum length of a sequence that the hardware can store

Parameters

nrEvents

max length of sequence

Returns

errorcode (DEVICE_OK if no error)

IsDASequenceable()

virtual int MM::SignalIO::IsDASequenceable ( bool &  isSequenceable ) const

pure virtual

Lets the UI know whether or not this DA device accepts sequences If the device is sequenceable, it is usually best to add a property through which the user can set "isSequenceable", since only the user knows whether the device is actually connected to a trigger source. If isDASequenceable returns true, the device adapter must also inherit the SequenceableDA class and provide method implementations.

Parameters

isSequenceable

signals whether other sequence functions will work

Returns

errorcode (DEVICE_OK if no error)

SendDASequence()

virtual int MM::SignalIO::SendDASequence ( )

pure virtual

Sends the complete sequence to the device If the individual data points were already send to the device, there is nothing to be done.

Returns

errorcode (DEVICE_OK if no error)

StartDASequence()

virtual int MM::SignalIO::StartDASequence ( )

pure virtual

Tells the device to start running a sequence (i.e. start switching between voltages send previously, triggered by a TTL

Returns

errorcode (DEVICE_OK if no error)

StopDASequence()

virtual int MM::SignalIO::StopDASequence ( )

pure virtual

Tells the device to stop running the sequence

Returns

errorcode (DEVICE_OK if no error)
