mikroElektronika DALI click User manual

1. Introduction
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all of the pins are
aligned correctly, push the board all
the way into the socket.

4. What is DALI?
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down so that
bottom side is facing you upwards. Place
shorter parts of the header pins in both
soldering pad locations.

Before using your click board™, make sure
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.

DALI click Manual
ver. 1.01
DALI Click™ is an add-on board in mikroBUS™
form factor. It’s a compact and easy solution
for adding Digital Addressable Lighting
Interface (DALI) to your design. It features two
optocouplers, push button and screw terminals.
DALI Click™ communicates with target board
microcontroller via four mikroBUS™lines (RST,
CS, PWM and INT). The board is designed to use
3.3V and 5V power supply. LED diode indicates
the presence of power supply.
DALI (Digital Addressable Lighting Interface)
is international standard for network based
systems that controls lighting in buildings.
Data between MCU and devices is transferred
over two-wire dierential bus by means of
asynchronous, half-duplex, serial protocol.
It is possible to address up to 64 devices in
DALI stand alone systems and more than 64
devices as DALI subsystem (gateways)

6. SMD Jumpers
Target board microcontroller can receive a
signal from DALI peripherals via interrupt pin
(INT) or input capture pin (PWM). Jumper J1
enables you to choose between these two
ways. J1 is soldered in the INT position by
default. There is one zero-ohm SMD jumper
J2 which is used to select between 3.3V or
5V power supply. Jumper J2 is soldered in the
3.3V position by default.
