Instrument Cluster
The information/status include gauges for various parameters,
indicators, and status-lights as well as acoustical effects.
Displays range from small dot matrix up to large color, high
resolution LCD displays
In addition to CAN/LIN interface there are LVDS interfaces.
LVDS interfaces are used to transfer large amounts of data via a high-
speed serial connection to an external location like a video screen.
The main load types in a Cluster are the stepper motors that operate
the gauges and the various indicator and back light sources.
The Stepper motor drivers are typically integrated in the μC.
LED drivers are typically multi-channel devices with serial interfaces to
the μC or Darlington arrays.
