Folks,

 

R3-1 of ADEiger is available.  This is from the release notes:

• Fixed a race condition with the Stream interface.
• The detector sends the first message over the ZMQ socket as soon as the "arm" command is sent when starting acquisition.
• However, the driver was not creating the ZMQ socket to receive those messages until after the "arm" command was sent. This was a race condition. It was failing on an Eiger2 at APS sector 34.
• This release creates the ZMQ socket before acquisition begins.
• Added "epsilon" PVs EnergyEps and WavelengthEps. Thanks to Bruno Martins for this.
• These are used to prevent minute or accidental changes to Energy and Wavelength from taking too long to be applied. Their values are now only updated if the difference between the desired and current value is greater than some configurable parameters. Specifically, changes in Wavelength only take effect if they result in a difference greater than WavelengthEps (default: 0.0005 Angstroms). Similarly, changes to PhotonEnergy, Threshold and Threshold2 only take effect if they are greater than EnergyEps (default: 0.05 eV).
• Improved the error diagnostic messages in the Stream API.
