Please refer to the 'DIABLO16-4DGL-Internal-
Functions.pdf' document for information on how
to set the DIABLO16 pin mappings.
Audio Interface 5.4.
The audio support in the DIABLO16 Processor
makes it better than its peers in the Graphics
processor range. PWM ensures better sound
quality with a volume range of 8 to 127. A simple
instruction empowers the user to execute the
audio files. Audio operation can be carried out
simultaneously with the execution of other
necessary instructions.
For a complete list of audio commands please
refer to the separate document titled 'DIABLO16-
4DGL-Internal-Functions.pdf'.
AUDIO pin (Audio PWM output):
External Amplifier Output pin. This pin provides a
16-bit DAC/PWM audio output to use with an
external audio amplifier. If unused then this pin
must be left open or floating.
AUDENB pin (Audio Enable output):
External Amplifier enable pin. This pin provides
ON/OFF amplifier control. If unused then this pin
must be left open or floating.
LOW: Disable external Audio amplifier.
HIGH: Enable external Audio amplifier.
Touch Screen Interface 5.5.
The DIABLO16 supports 4-Wire resistive touch
panels. The diagram below shows a simplified
interface between the DIABLO16 and a touch
panel.
XR pin (Touch Panel X-Read input):
4-Wire Resistive Touch Screen X-Read analog
signal. Connect this pin to XR or X+ signal of the
touch panel.
XL pin (Touch Panel X-Drive output):
4-Wire Resistive Touch Screen X Drive signal.
Connect this pin to XL or X- signal of the touch
panel.
YU pin (Touch Panel Y-Read input):
4-Wire Resistive Touch Screen Y-Read analog
signal. Connect this pin to YU or Y+ signal of the
touch panel.
YD pin (Touch Panel Y-Drive output):
4-Wire Resistive Touch Screen Y Drive signal.
Connect this pin to YD or Y- signal of the touch
panel.
