mesytec-mvlc - driver and utilities for the mesytec MVLC VME Controller

mesytec-mvlc is a driver and utility library for the Mesytec MVLC VME controller written in C++. The library consists of low-level code for accessing MVLCs over USB or Ethernet and higher-level communication logic for reading and writing internal MVLC registers and accessing VME modules. Additionally the basic blocks needed to build high-performance MVLC based DAQ readout systems are provided:

• Configuration holding the setup and readout information for a single VME crate containing multiple VME modules.

• Multithreaded readout worker and listfile writer using fast data compression (LZ4 or ZIP deflate).

• Readout parser which is able to handle potential ethernet packet loss.

• Live access to readout data on a best effort basis. Sniffing at the data stream does not block or slow down the readout.

• Examples showing how to combine the above parts into a working readout system and how to replay data from a previously recorded listfile.

• Various counters for monitoring the system.

mesytec-mvlc is used in the mvme DAQ software to implement MVLC support.
