FED Library

This software review covers the FED Crate's control and monitoring systems, error handling, data transmission, and hardware self-monitoring capabilities. It provides insights on programming, communication protocols, and software-hardware interactions. The conclusion highlights operational status and future tasks.

  4. DDU Error Checking

  5. FED Library (C++) • Controls/Monitors/Updates DDU/DCC Electronic Boards • CAEN VME Crate Controller • JTAG PROM/FPGA programming • Read DDU/DCC Registers for Debugging • Monitor Voltages/Temperatures • Very Few Write Registers • VME Write Registers • Kill Fiber • Use Fiber • Scaling Local Farm • FMM Error Register • Test Registers

  6. FED Library (C++) • Modeled directly on Peripheral Crate Library • (see M. Von der Mey previous talk) • Similar structure reduces programming work • XDAQ communications/messaging identical • JTAG Firmware (*.svf) Programming Routines Identical • Voltage/Thermometer and Register Readout Identica • Problems found in Peripheral Crate Software can be fixed • in FED Crate -Software and visa versa • FED Crate – Run Initialization • No special initialization necessary. TTC signals only.

  7. FED Library (C++) • FED Crate Hardware is Self Monitoring • Hardware sends VME IRQ interrupt on Error Detection • 4 threaded processes (one for each crate) capture/service VME interrupts • use CAENVME_IRQWait(); CAENVME_IACKCycle(); • Threaded processes can request Global Reset from FMM • FMM is signaled via VME write to a DDU register • Hardware can also request Global Reset independently • DCS (see V. Sytnik’s Talk) • Board Temperature/Voltage will be accessed periodically • through Slow Control

  8. Another HyperDAQ GUI. There are 10 more Unique pages I won’t show.

  9. FED Library (C++) Conclusions • FED Library Status • Software fully operational • XDAQ Soap messaging for Run Control working • XDAQ HyperDAQ GUI for local monitoring fully working • VME Interrupt and FMM signaling threads fully working To do: • xml initialization file  Oracle data base • Firmware not presently archivaled, will do soon • Library not tested for multi-crates (will work)
