Code Mercenaries

1. Features

• DALI master

• I2C to DALI bridge

• Turns standard light switch into a DALI master

• According to DIN EN 62386-103

• Simplified access to DALI

• Minimal external circuitry

• 5 V supply

1.1 Variants

LED-Warrior09 is available in DIL8, SOIC8

packages, or as modules.

1.2 LW09-01MOD

The LW09-01MOD is a ready to use module. It is

primarily intended to be used as a I2C to DALI

bridge and needs a 5 V power supply. Two swit-

ches may be connected.

1.3 LW09-02MOD

The LW09-02MOD is a ready to use module for

stand alone devices. LW09-02MOD can be used to

turn switches into DALI controllers or as a I2C to

DALI bridge. It extracts its power supply from the

DALI bus and can provide some power for

additional electronics like a RF receiver.

1.4 Custom variants

Custom variants are possible for the chips as well

as for the modules.

2. Functional overview

LED-Warrior09 is a type II DALI master. It can

coexist with other masters on the same bus but is

not addressable.

LED-Warrior09 generates the necessary DALI

commands to set light levels from simple I2C

commands, or two switch inputs.

Standard light switches can be turned into DALI

masters with the LED-Warrior09. The function of

the two switch inputs is programmable via I2C.

On/off switching and dimming can be controlled

by one or two switches for individual DALI

ballasts, groups, or broadcast.

3. Pin Descriptions (Chip SOIC-8 or DIL-8)

Vcc

5 V supply voltage positive input.

GND

Supply voltage negative input.

SDA

Data line of I2C interface.

High impedance input and open drain output.

SCL

Clock line of I2C interface.

High impedance input and open drain output.

DALIrx

Receive data input from DALI bus.

Connect a DALI bus receiver to this pin.

Positive logic, high = high level on bus.

High impedance input.

DALItx

Transmit data output to DALI bus.

Connect a DALI bus driver to this pin.

Positive logic, high = high level on bus.

Open drain output with internal pull up resistor for

high.

SW0, SW1

Switch inputs for direct lighting control.

The function of these pins can be programmed via

I2C.

Factory default setting is for two momentary

switches to control on/off for short action and up/

down dimming for press and hold.

Inputs with internal pull up resistors.

LED-Warrior09 4. I2C Addressing LED-Warrior09 uses $20 (7 bit value, needs to be shifted and extended by R/W bit: 0100 000R) as the factory default I2C address. Reassigning a different address is possible via I2C commands. 4.1 I2C Commands Commands are implemented via register addresses that are transmitted as the first byte following the I2C address byte.

LED-Warrior09 4.3.3 $00 - OFF Command code $00 switches the addressed lamp off. 4.3.4 $01 - UP Command code $01 fades the addressed lamp up for 200ms with its internally programmed rate. 4.3.5 $02 - DOWN Command code $02 fades the addressed lamp down for 200ms with its internally programmed rate. 4.3.6 $03 - STEP UP Command code $03 steps the power of the addressed lamp up by one step. It does not switch a lamp on. 4.3.

LED-Warrior09 Two switch up/down dimming sets the addressed devices to maximum level on a short press on SW0 and off on a short press on SW1. Holding down SW0 results in dimming up and holding SW1 dims down. Code Mercenaries The first byte has to contain the address in normal format (i.e. values 0 to 127), the second byte must contain the value of the first byte XORed with $FF.
