PICASO Processor
The module is designed around the PICASO
Graphics Processor from 4D-Labs.
The PICASO GPU is a smart Controller and the
interface to the TFT- LCD displays is almost plug-n-
play.
All of the data and control signals are provided by
the chip to interface directly to the display.
Powerful graphics, text, image, animation and
countless more features are built right inside the
chip.
The data sheet for the processor is available from
the
the chip to interface directly to the display.

Audio
Audio playback support in the PICASO Processor
enables the µLCD-43 module to play audio WAV
files stored in the micro-SD memory card. PWM and
an on-board audio amplifier with 8Ω speaker
ensure ample audio output capability. A simple
instruction enables the user to play/pause/stop
audio files while continuing the execution of the
user application code, such as display updates,
touch recognition, communications, etc. The audio
system also allows real time pitch change of audio
samples.
For a complete list of audio commands please refer
to the separate document titled:
“PICASO-4DGL-Internal-Functions.pdf”
Note: The on-board speaker is a small device
designed to project into an audio cavity. It is not
very loud by itself. To enable louder audio, it is
recommended to use a larger external 8Ω speaker.
See the ‘Hardware Interface Pins’ – ‘System Pins’
section for more information.

SD/SDHC Memory Cards
The module supports
micro-SD memory cards
via the on-board micro-
SD
connector.
The
memory card is used for
all multimedia file retrieval such as images,
animations and movie clips. The memory card can
also be used as general purpose storage for data
logging applications. Support is available for off the
shelf micro-SD and high capacity HC memory cards
(4GB and above).

Note: A microSD card capable of SPI is a
requirement for all 4D Systems’ display modules
powered by Goldelox, Picaso or Diablo16
Processors. If a non-SPI compatible card is used, it
