Module ImgAlgos::UsdUsbEncoderFilter

This ImgAlgos::UsdUsbEncoderFilter (ImgAlgos > V00-03-43) module is created by request of Thomas Kroll for experiment with mobile rack in SACLA .

It has This psana module contains an example of how to get UsdUsb::DataV1 object and timestime-tamps stamps from different data sources for event synchronization purpose.

Functionality:

To work with time-code objects it uses helper class TimeCode. It loads input timing information from file defined by the  ifname  and store it in the std::vector<TimeCode> member object. For each event the TimeCode object is defined from data; time stamp from PSEvt::EventId, and unique code from UsdUsb::DataV1. TheTimeCode object from data is compared with information loaded from the input file. If the TimeCode object from data is consistent with one of the records in the file event is passed for further processing, otherwise discarded.

  • +4 - open/close info for output file
  • +8 - filter summary
  • +16 - content of the UsdUsb::ConfigV1 object
  • +32 - content of the UsdUsb::DataV1 object

 

Input (ifname) and output (ofname) files have any number of records of the same format. Each record consists of four integer numbers:

  •     timestamp sec (uint32_t),
  •     timestamp nsec (uint32_t),
  •     UsdUsb 6-bit code (uint8_t),
  •     user defined counter (unsigned).

Example of the input/output file content:
