IDS peak 2.8.0 / uEye+ firmware 3.33

Latches the chunk value with the selected source signal, i.e. defines at which time the selected chunk data will be captured.

Values description

•ExposureStart: Chunk data is captured when an exposure starts.

•ExposureTrigger: Chunk data is captured when the camera receives a valid trigger.

•ReadOutStart: Chunk data is captured when the readout of the sensor starts.

Code example

C++

// Determine the current entry of ChunkLatchTriggerSource
std::string value = nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("ChunkLatchTriggerSource")->CurrentEntry()->SymbolicValue();
// Get a list of all available entries of ChunkLatchTriggerSource
auto allEntries = nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("ChunkLatchTriggerSource")->Entries();
std::vector<std::shared_ptr<peak::core::nodes::EnumerationEntryNode>> availableEntries;
for(const auto & entry : allEntries)
{
  if ((entry->AccessStatus()!=peak::core::nodes::NodeAccessStatus::NotAvailable)
          && (entry->AccessStatus()!=peak::core::nodes::NodeAccessStatus::NotImplemented))
  {
      availableEntries.emplace_back(entry);
  }
}
// Set ChunkLatchTriggerSource to "ExposureStart"
nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("ChunkLatchTriggerSource")->SetCurrentEntry("ExposureStart");

C#

// Determine the current entry of ChunkLatchTriggerSource
string value = nodeMapRemoteDevice.FindNode<peak.core.nodes.EnumerationNode>("ChunkLatchTriggerSource").CurrentEntry().SymbolicValue();
// Get a list of all available entries of ChunkLatchTriggerSource
allEntries = nodeMapRemoteDevice.FindNode<peak.core.nodes.EnumerationNode>("ChunkLatchTriggerSource").Entries();
List<string> availableEntries = new List<string>();
for(int i = 0; i < allEntries.Count(); ++i)
{
  if ((allEntries[i].AccessStatus() != peak.core.nodes.NodeAccessStatus.NotAvailable)
          && (allEntries[i].AccessStatus() != peak.core.nodes.NodeAccessStatus.NotImplemented))
  {
      availableEntries.Add(allEntries[i].SymbolicValue());
  }
}
// Set ChunkLatchTriggerSource to "ExposureStart"
nodeMapRemoteDevice.FindNode<peak.core.nodes.EnumerationNode>("ChunkLatchTriggerSource").SetCurrentEntry("ExposureStart");

Python
