A DISPLAX Active OR Tag provides two types of feedback:
Light feedback through a full ring light around the tag
Vibration feedback using the built-in vibration motor
These features can be triggered in two ways:
In Displax Connect (mainly for testing purposes)
Note: After executing a feedback effect, the sleep mode timeout is reset.
To trigger a light effect, the following parameters must be defined along with the Tag ID:
color – RGB value (hexadecimal)
effect – predefined light effect ID
number of cycles – how many times the effect repeats
time duration – time in milliseconds for each cycle
Color: RGB hex code (example: FF0000 for red)
Effect Types:
effect ID | Effect | Comments |
0 | FadeToColor | Fade from last effect color to new color. The fade takes time duration milisseconds to reach the final color. This effect is power consuming, as the final color will remain active, until a different effect is sent or the tag enters sleep mode. |
1 | Blink | Fade from last color to color (20% duty cycle), maintains the color (60% duty cycle), and fade to blackness (20% duty cycle). |
2 | ShortPulse | Fade from last color to color (20% duty cycle) and fade to blackness (80% duty cycle). |
3 | TriangularWave | Fade from last color to color (50% duty cycle) and fade to blackness (50% duty cycle). |
4 | ToothsawWave | Fade from last color to color (99% duty cycle) and goes to blackness (1% duty cycle). |
5 | Heartbeat | color (10% duty cycle), followed by blackness (10% duty cycle), followed by color with 20% brigthness (20% duty cycle), followed by darkness (60% duty cycle) |
To trigger a vibration effect, the following parameters must be defined along with the Tag ID:
number of cycles – repetitions of the vibration sequence
level – vibration intensity (0–100)
time_on – milliseconds motor stays on per cycle
time_off – milliseconds motor stays off per cycle
Number of cycles: Defines total repetitions. Each cycle = time_on + time_off.
Level: Vibration intensity (0 = none, 100 = max).
Time_on: Motor on duration (ms).
Time_off: Motor off duration (ms).
Example: With level = 80, number of cycles = 3, time_on = 200 ms, time_off = 100 ms, the motor vibrates strongly for 200 ms, pauses 100 ms, and repeats three times.
Light and vibration effects can be used independently or together.
Use Displax Connect to test feedback functions before full SDK integration.
Effects reset the sleep mode timer, keeping the tag active longer.
