Speaker – Sound and Music Generation
3.4.
The µOLED-96/128/160-G2 µOLED display modules and µLCD-144-G2, µLCD-24/28/32/32WPTU µLCD display
modules are capable of generating complex sounds and music from their respective I/O pins. Using a shunt
and shorting the relevant AUD pin on the Jumper Header (refer to section 3.9 for further information), audio
generation is possible from any of the Display Modules and played out of the on-board speaker on the
Development Board.
Joystick – 5 Position Multi Switch
3.5.
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, and therefore display modules using the GOLDELOX processor are capable of
reading this voltage in with its Analogue to Digital (A2D) converter. The IO1 pin of µOLED-96/128/160-G2 and
µLCD-144-G2 display modules can be programmed as an A2D input using the Workshop software suite.
Utilising the A2D feature each individual switch position voltage value can be read and decoded. Refer to
section 3.9 for further information.
Power Supply
3.6.
The 4DevBoard can be powered by the 5 Volts supply provided by the 4D Programming Cable or it can be
powered by an external wall-plug (9 Volts to 12 Volts DC) centre tap positive. The board also has provisions for
soldering a flying lead 9V battery clip. Both the wall plug and the 9V battery clip are not provided.
