RGB Button Guide

This page describes the information about the RGB button

The button on the DAQ-A contains a color-changing RGB LED inside it to show the user the current system state. The LED is daylight-readable from afar and can be adjusted for brightness.

RGB LED Modes

The DAQ-A features a comprehensive LED status system that provides visual feedback for both system state and GPS readiness.

System Status LEDs

LED Color	Mode	Status
⚫BLACK (OFF)	Solid	No Power System Booting
🔴RED	Solid	System Starting Data Logging OFF
🟢GREEN	Solid	Data Logging ON Image Capture OFF GPS Ready
🟢GREEN	Fade/Pulse	Data Logging ON Image Capture ON
🟣PURPLE/INDIGO	Flash	Trigger Pulse (momentary flash during image capture)
🔵BLUE	Flashing	Firmware Updating

GPS Readiness Status LEDs (NEW in v1.03)

The v1.03 firmware introduces GPS readiness checking with intuitive color progression from searching to ready:

LED Color	Pattern	GPS Status	Description
🟠ORANGE	Slow Flash (1s on/off)	Searching	Searching for GPS signal
🟡YELLOW	Fast Flash (0.3s on/off)	Acquiring	Getting GPS lock (partial signal)
🟢GREEN	Solid	Ready	GPS locked and ready for capture
⚪WHITE/PINK	Fast Flash (0.3s on/off)	Error	GPS error or malfunction
🔴ORANGE-RED	Fast Flash (0.3s on/off)	Timeout	GPS readiness timeout (exceeded wait time)

Typical GPS Startup Sequence

When powering on the DAQ-A, you will see this LED progression as the GPS acquires a signal:

🔴 RED (solid) → 🟠 ORANGE (slow flash) → 🟡 YELLOW (fast flash) → 🟢 GREEN (solid)
System Boot     → GPS Searching        → GPS Acquiring          → Ready for Capture

During Capture Session

Once capture begins, the LED will pulse and flash to indicate activity:

🟢 GREEN (solid) → 🟢 GREEN (pulsing) → 🟣 PURPLE (flash) → 🟢 GREEN (pulsing)
Ready            → PWM Active         → Trigger Pulse    → PWM Active

Dimming or Turning OFF the Button LED

Most of the time you will probably not need to adjust the LED brightness. For the times you do need to dim the LED or turn it off you just need to edit the "led_brightness" parameter.

"led_brightness": 10

To turn the LED off, edit parameter "led_brightness" to a value of 0.

The brightness value range is 1-10, with 1 being the dimmest and 10 the brightest.

When the image capture sequence is on, the LED will fade between the max brightness set by the "led_brightness" parameter and a value of 1 (lowest but not off). For example, if "led_brightness" is set to 10 (default), it will fade between 10 and 1 (10-1-10-1...).
