2. Soldering the headers 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. 1 DALI click 2 3 1. Introduction 4. What is DALI 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 differential bus by means of Turn the board upside down so that Turn the board upward again. Make sure asynchronous, half-duplex, serial protocol. bottom side is facing you upwards. Place to align the headers so that they are It is possible to address up to 64 devices in shorter parts of the header pins in both perpendicular to the board, then solder the DALI stand alone systems and more than 64 soldering pad locations. pins carefully. devices as DALI subsystem (gateways) DALI Click is an add-on board in mikroBUS 3. Plugging the board in form factor. Its a compact and easy solution click for adding Digital Addressable Lighting Once you have soldered the headers your Interface (DALI) to your design. It features two board is ready to be placed into desired BOARD optocouplers, push button and screw terminals. mikroBUS socket. Make sure to align the www.mikroe.com DALI Click communicates with target board cut in the lower-right part of the board microcontroller via four mikroBUS lines (RST, with the markings on the silkscreen at the DALI click Manual CS, PWM and INT). The board is designed to use mikroBUS socket. If all of the pins are ver. 1.01 3.3V and 5V power supply. LED diode indicates aligned correctly, push the board all the presence of power supply. the way into the socket. 0 100000 0222216. SMD Jumpers 5. DALI Click Board Schematic 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 VCC DALI Vdali VCC J2 which is used to select between 3.3V or R1 C1 5V power supply. Jumper J2 is soldered in the R4 R2 R3 1K0 10K 1K2 +3V3 +5V 3.3V position by default. 100 LD1 220pF U1 YELLOW VCC +3V3 ICP ICP R5 AN PWM DALI TX DALI TX INT DALI RX RST INT PHY SEL INT 6K8 CS TX TLP181 SCK RX J1 7.
