Fork

This repo is a fork with a few special enhancements:

• Defines to setup dali (see below)
• Support for rp2040, ESP32, ESP8266*, AVR*
• Supports externally called timer isr (DALI_NO_TIMER)
• added functions for easy broadcast telegrams
• added Dali Commands (DaliCmdExtendedDT8)
• added receive dali commands
• added callback for dali activity (ex to use a led to show activity)
• use of macros for set/get BusLevel to reduce time spent in interrupt

* not tested

arduino-dali

A timer-based DALI library for Arduino

This library allows you to create a DALI controller/gateway with an Arduino device. It supports sending commands, receiving responses and commissioning devices. It requires the TimerOne library for transmission and the PinChangeInterrupt library for reception. These libraries need to be installed with the Library Manager in the Arduino IDE.

Library Documentation: https://hubsif.github.io/arduino-dali/

Short example usage:

#include <Dali.h>

void DaliCommand(uint8_t *data, uint8_t len)
{
  // do wathever you want with this information
  // but keep it really short!
  // to long and you miss commands or corrupt sending commands
}

void DaliActivity()
{
  // do wathever you want with this information
  // but keep it really short! Really short!
  // to long and you miss commands or corrupt sending commands
}

void setup() {
  Dali.begin(2, 3);

  // add a callback for received commands
  Dali.setCallback(DaliCommand);

  // add a callback for activity notification (use for leds or something)
  Dali.setActivityCallback(DaliActivity);
}

void loop() {
  // blink ballast with short address 3
  Dali.sendArc(3, 254);
  // alternatively to prevent fading you could use
  // Dali.sendCmd(3, Dali.CMD_RECALL_MAX);
  delay(1000);

  Dali.sendArc(3, 0);
  // alternatively to prevent fading you could use
  // Dali.sendCmd(3, Dali.CMD_OFF);
  delay(1000);
}

Use Defines

Define	Description	Values	Default
DALI_TIMER	Specify Timer Instance	0-3 (rp2040) 0-1 (esp32/8266) 1-2 (avr)	0
DALI_NO_TIMER	Don`t use a timer. DaliBusClass::timerISR will be called external	-	-
DALI_NO_COMMISSIONING	Exclude commissioning Code	-	-
DALI_DONT_EXPORT	Don`t automaticly export a Dali instance	-	-
DALI_NO_COLLISSION_CHECK	Remove collission check if you are the only master (use with caution)	-	-
