Code Mercenaries

1. Features

• IEC62386 master

• I2C to IEC62386 bridge

• Turns standard light switch into a IEC62386

master

• According to DIN EN 62386-103

• Simplified access to IEC62386

• 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 IEC62386

bridge and needs a 5 V power supply. Two

switches 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 IEC62386 controllers or as a I2C

to IEC62386 bridge. It extracts its power supply

from the IEC62386 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 IEC62386 master. It

can coexist with other masters on the same bus but

is not addressable.

LED-Warrior09 generates the necessary IEC62386

commands to set light levels from simple I2C

commands, or two switch inputs.

Standard light switches can be turned into

IEC62386 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

IEC62386 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.

DArx

Receive data input from IEC62386 bus.

Connect a IEC62386 bus receiver to this pin.

Positive logic, high = high level on bus.

High impedance input.

DAtx

Transmit data output to IEC62386 bus.

Connect a IEC62386 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.
PAGE 4
LED-Warrior09 The functions of the other IEC62386 commands are described in the following section. 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.
PAGE 5
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. Two switch on/off only switches to maximum level or off and does not allow dimming, holding down a switch does not result in different behaviour. Single switch dimming does toggle between off and maximum level if pressed briefly. Holding down the switch when the lamp is off will result in up dimming.
