logiHAC Clips

The logiHAC Automotive Hybrid Instrument Cluster shows the welcome screen and switches different instrumentation lights on and off.

Hybrid Cluster can work automatically and present different cluster screens that can be exchanged during a drive. This movie clip shows just the beginning of this automatic mode. Provided HMI allows for switching into hand-controlled mode of operation.

Needles' (instrumentation pointers) controlled by stepper motors must be properly positioned at the start-up time. The logiHAC Automotive Hybrid Instrument Cluster sets up the needles' zero position in two different ways:
- Return To Zero: needles are forced back for a predetermined number of steps
- Stall Detection: needles are stepped back while dedicated electronics monitors their position

Stepper motors are controlled by Xylon's logiSTEP Stepper Motor Controller IP core.

This movie shows fast Return To Zero (RTZ) positioning at the startup. Needles are forced towards gauge scale's needle stopper. The logiSTEP Stepper Motor Controller support RTZ in the noiseless microstepping mode. Very fast needle driving can prevent or minimize needle bouncing at the stopper.

Integration of video inputs, such as the input from the Rear-View Camera, is an important feature supportable by instrument clusters with high-resolution LCD display. The logiHAC supports it by the logiWIN Versatile Video Input IP core.

Xilinx FPGA cannot handle fast analog inputs. This clip shows demo hand control. Input potentiometers are read by the PIC microcontroller with integrated ADCs. The PIC sends read data to the FPGA through the SPI serial bus interface.

The logiHAC simulates driving conditions which do not require extremely fast needle movements. This demo shows faster needs achievable by the logiSTEP IP core. The needles can be moved even faster without loosing a single microstep.
