Description
User Interface
Data Sheet
The user interface is the 5 pin male header,
underneath the board. This provides direct access
to the same 5 pin header on the uOLED-128-G1
display modules (extended electrically). It is also a
used to attach either a uUSB-MB5 or uUSB-CE5
(USB to Serial Converters) for connecting the
display module to a PC for development and
programming purposes as illustrated below.
The
CB-128-G1
is a compact carrier board
designed to provide a simple means of adding user
input to the already capable uOLED-128-G1(SGC)
(Serial Platform) and the uOLED-128-G1(GFX)
(4DGL Platform) range of intelligent display
modules. The tiny 5-position joystick, along with
an on-board speaker, facilitates user input and
output for these displays.
The joystick can be used for menu navigation,
exciting game play or any kind of user input
needed for your applications.
The small speaker can be used for game sounds,
audible feedback for user interaction with
applications or just to experiment with the sound
capabilities of the embedded GOLDELOX-SGC or
the GOLDELOX-GFX2 processors on the display
modules.
The carrier board also provides a secure stable
attachment for the OLED-128-G1 range of displays.
When the display is mounted on the carrier board,
the combination provides additional protection for
the display.

Attaching the Display Module
The following images illustrate various ways of
attaching the uOLED-128-G1(SGC) and the uOLED-
128-G1(GFX) display modules to the CB-128-G1
carrier board.
Joystick Circuit
The The Joystick is a 5 position multi switch and
each position connects to a junction of a resistor
ladder network that forms a voltage divider.
uOLED-128-G1(SGC) Serial Display:
The output of
the Joystick connects directly to the
SWITCH
pin.
Each Joystick position is interpreted as 1 of 5
buttons or switches.
uOLED-128-G1(GFX) 4DGL Display:
The output of
the Joystick voltage divider connects directly to
the
IO1
pin. The IO1 pin can be programmed as an
Analogue to Digital (A2D) converter input under
4DGL. Utilising the A2D feature, each individual
switch position voltage value can be read and
decoded. The IO1 pin of the display modules are
directly connected to the output of the joystick
voltage divider circuit.

Note:
The uOLED-128-G1(SGC) (Serial platform)
and the uOLED-128-G1(GFX) (4DGL platform)
display modules are both similar electrically and
mechanically.

Sound Circuit
The uOLED-128-G1 range of display modules are
capable of generating complex sounds and music
from their respective I/O pins.
The
SOUND
pin of uOLED-128-G1(SGC) and
IO2
pin of uOLED-128-G1(GFX) is connected to the
speaker circuit as illustrated in the circuit below.
