software
CMA3000 DEMO KIT is controlled via USB serial port by GUI software.
The GUI software has four different display modes. The CMA3000 sensor can be set to:
-
normal measurement mode,
-
normal measurement mode with free fall detection enabled and
-
motion detection mode.
The interrupt detected due free fall or motion is indicated by led indicator and sound (if PC sounds
are enabled). Once interrupt is detected, the interrupt has to be cleared by user by pressing the red
led. The led appears on display only when the interrupt is detected.
The four different GUI displays and start up screens are presented below.
