General Reference Complex

How Does It Work?

The General Reference is a multifunctional solution featuring the following integrated demonstrations:

1. LED Control:
   • Individually turn on and off up to four LEDs.
   • Toggle all LEDs simultaneously or set all to ON/OFF.
2. Graph Simulation:
   • Display dynamic curves, such as ECG or sine waves.
   • Control graph behavior with a potentiometer in play, pause, and stop modes.
3. Pressure Measurement:
   • Gauge-style graph with a pointer displaying pressure values.
   • Visual alarms based on received pressure values.
4. Text and QR Code Manipulation:
   • Receive text, invert it, and display it directly on the screen.
5. Volume Adjustment:
   • Graphical representation of volume using X and Y bars.
6. Date and Time Adjustment:
   • Calendar: Direct date adjustment on the display.
   • Scrolling Picker: Intuitive interface for setting the time.
7. Settings Screen:
   • Brightness Adjustment: Control the display's backlight intensity.
   • Buzzer Configuration:
     • Set the time interval for the buzzer sound.
     • Test button to hear the buzzer for the configured time.
     • Save button to store the defined interval as default.
   • Reset Button: Restarts the display.
   • Display Information: Shows details like firmware version and other technical data.
