LEDFEEDBACK

Path: ../src/components/LEDFeedback.h

Revision History: Initial documentation

This component controls an LED strip (NeoPixel) with various modes like fade, range display, and tri-color blink. It integrates with Modbus for industrial control.

REQUIREMENTS

• Pins: Data pin for NeoPixel (configurable via PIN_LED_FEEDBACK).
• Dependencies:
• Adafruit_NeoPixel library for LED control.
• ModbusTCP library for communication.
• config.h and config-modbus.h for configurations.

FEATURES

• Multiple LED modes (OFF, Fade Red-Blue, Range display, Tri-Color Blink).
• Modbus integration for remote control and monitoring.
• Configurable LED strip parameters (pin, pixel count, Modbus address).

TODOS

• Add more LED modes (e.g., SOLID_COLOR, RAINBOW).
• Implement brightness control via Modbus.
• Enhance error handling in Modbus communication.

EXAMPLE

#ifdef PIN_LED_FEEDBACK_0
ledFeedback_0 = new LEDFeedback(
this,                  // owner
PIN_LED_FEEDBACK_0,    // pin
LED_PIXEL_COUNT_0,     // pixelCount
ID_LED_FEEDBACK_0,     // id
LED_FEEDBACK_0_MB_ADDR // modbusAddress
);
if (ledFeedback_0)
{
components.push_back(ledFeedback_0);
Log.infoln(F("LEDFeedback_0 initialized. Pin:%d, Count:%d, ID:%d, MB:%d"),
PIN_LED_FEEDBACK_0, LED_PIXEL_COUNT_0,
ID_LED_FEEDBACK_0, LED_FEEDBACK_0_MB_ADDR);
}
z[
{
Log.errorln(F("LEDFeedback_0 initialization failed."));
}
#endif
