mikroElektronika AlphaNum R click Quick Start Manual

AlphaNum R click
1. Introduction
AlphaNum R click is a simple solution for
™
adding 14-segment alphanumeric displays
to your device. The board carries two TLC5926
16-bit Constant-Current LED sink Drivers
as well as a dual character LED 14-segment
display. AlphaNum click ™ communicates with
the target board through mikroBUS RST, CS,
™
SCK, MISO, MOSI, PWM and INT pins (marked
here as LE2, LE1, CLK, DOUT, DIN, NUMSEL# and
NUMSEL respectively). The board is designed
to use either a 3.3V or 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
While a standard 7-segment display is
sufficient only for displaying digits, a
14-segment display (also known as a
starburst display) is necessary for legibly
rendering the ISO basic Latin alphabet. The
dual character display onboard AlphaNum
click also contain two commas (decimal
™
points if used for digits) as additional
segments. The two TLC5926 ICs contain 16-
bit shift registers and data latches to convert
serial input data into parallel output format.
