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 BarGraph click 2 3 4. Essential features 1. Introduction BarGraph Click with its JSB-R102510Z and 74HC595 ICs gives additional 10 segment light bar display to your design. The 74HC595 IC contains an 8-bit serial- in, parallel/serial-out shift register as well as 8-bit storage register. The storage Turn the board upside down so that Turn the board upward again. Make sure registers has parallel 3-state outputs. bottom side is facing you upwards. Place to align the headers so that they are Separate clocks are provided for both the shorter parts of the header pins in both perpendicular to the board, then solder the shift and storage register. Shift register soldering pad locations. pins carefully. has a direct overriding clear input. BarGraph Click is an accessory board in mikroBUS form factor. Its a compact 3. Plugging the board in and easy solution for adding ten-segment click light bar display to your design. It features Once you have soldered the headers your JSB-R102510Z light bar display as well board is ready to be placed into desired BOARD as two 74HC595 shift registers. BarGraph mikroBUS socket. Make sure to align the www.mikroe.com Click communicates with the target board cut in the lower-right part of the board microcontroller via mikroBUS SPI (MOSI, with the markings on the silkscreen at the BarGraph click Manual MISO, SCK, CS), RST and PWM lines. The mikroBUS socket. If all of the pins are ver. 1.00 board is designed to use 3.3V and 5V aligned correctly, push the board all power supply. LED diode (GREEN) indicates the way into the socket. the presence of power supply. 0 100000 0237546. SMD Jumpers 5. BarGraph Click Board Schematic There is one zero-ohm SMD jumper J1 used to select whether 3.3V or 5V power supply is used. Jumper J1 is soldered in 3.3V position by default.
