  5. Digital I/O Fiber link FPGA Main WFS components: Microgate BCU39 and BCU47 • HO ccd frame grabber • Slope computer • Relays bank • Technical viewer frame grabber • Tip-tilt sine wave generator DSP Memory

  6. Other (hardware) components • CCD controllers • Linear stage controllers • Relay switches for powering on/off devices • Pupil rerotator controller • Stepper motor controllers for filter wheels and ADC • Reference lamp controller • Temperature sensors • Various network devices

  7. HW control software • One process for each hardware device • Each process has only two interfaces: • one socket to MsgD-RTDB • one socket to the HW device • Mostly written in C/C++ with a series of libraries for common functions • Commands and answers are implemented using MsgD-RTDB variables.

  9. Engineering interface WFS diagnostic data: Ethernet UDP Diagnostic process Shared memory • CCD frames • Wavefront slopes • Mirror commands • Downloaded at 70 Hz (limited by protocol speed) • -> an internal 4000-frames buffer is available Monitoring scripts

  10. Engineering interface Python classes MSGLIB AO arbitrator MsgD RTDB MSGLIB C Wrapper MSGLIB MSGLIB MSGLIB Python scripting interface To controller programs Python scripts

  11. Python classes MSGLIB MsgD RTDB MSGLIB C Wrapper MSGLIB MSGLIB Graphic interface MSGLIB Engineering interface • Graphical & commandline • Mainly Python with some custom C/C++ modules for realtime sections (like displays) • Graphic library: QT 3.3 + using the PyQT wrapper • Numeric library: Python numarray module To controller programs

  12. Calibration routines • Calibration (usually) requires tight interaction between WFS and secondary mirror operations. We have a mix of Python scripts an IDL routines • Python • scripts are short-lived (but fully featured) MsgD-RTBD clients acquiring the calibration data. • IDL • used to make calculations because of the extensive math library. • Examples: pupil acquisition, reconstruction matrix calculation, etc.
