mikroElektronika 7x10 R click Manual

7x10 R click
1. Introduction
7x10 R click carries a matrix of 70 red LEDs
driven by a pair of 8-bit serial-in, parallel-
out shift registers, a Darlington Transistor
array and a Johnson counter. The click
communicates with the target MCU through
the mikroBUS™ SPI interface (SCK, SDO,
SDI), with additional functionality provided
by R CLK, MR#, LATCH and R RST pins. 7x10
R click is designed to use either a 3.3V or a
5V power supply.
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.

Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the 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 the
™
pins are aligned correctly,
push the board all the way
into the socket.
4. Essential features
7x5 is a standard resolution for displaying
ASCII characters, so 7x10 click is essentially
a dual-character display capable of showing
letters in more readable typefaces compared
to a 14-segment display. The dot matrix can
also show scrolling text, thus fitting longer
messages in small space. The pair of 8-bit
SIPO shift registers drive the display. The
current amplification necessary for driving
the LEDs is performed by a Darlington
Transistor array while a Johnson counter
performs the necessary LED multiplex.
