N2 - We describe the new control system for the PICNIC near-infrared camera
and the visible star tracker, implemented at the IOTA interferometer,
based on the ALTERA Complex Programmable Logic Device (CPLD) technology.
These digital components provide an adaptive interface between the
control system and the cameras used at IOTA, allowing flexibility when
connecting very different devices. In particular the clocking and
processing circuits used for the PICNIC camera can be changed in
milliseconds during normal operation. The camera can then switch between
full quadrant readout mode used for alignment and diagnostics, and a N
pixel readout mode used for science operation.
