1 Introduction
The ISD93xx evaluation board –picture shown below, is a small but rather functionally
complete and flexible board. It consists of two parts, of which if broken either one can run
independently.
Left part –the ISD93xx demo board
Right part –the ISD_Nulink JTAG interface board, which is a Nuc123 application
system
With a USB cable, the evaluation board provides the user a complete hardware
environment for the ISD93xx project development. Under Keil the user can burn the
project program code into the in-system flash and do debugging; also the user can use
ICP tool provided by Nuvoton to burn the ISD93xx configuration bytes, in-system
application ROM, in-system data flash, and the external SPI flash on the ISD93xx demo
board.
In the later stage of a project development, the ISD93xx demo board might be required to
run in standalone mode. In this case, the user can simply break the evaluation board, and
let the left part –the ISD93xx demo board run alone. After the evaluation board is broken
into two pieces, and if the user needs to re-program or debug the system, then user may
either reconnect the two boards back together again via JP9 and JP12, or use Nu_Link
JTAG dongle to provide control interface, see picture below.

3 Demo Code
The ISD9300 series evaluation board comes with demo functions ready, which means
the ISD93xx device on board are shipped with default demo code burned. Once the
ISD93xx Touch Board and power supply are connected –see below for the complete
demo system, the system is ready to demo the following functions:
RGB LED randomly changes color when device is idle
oDriven by three channel PWM
Simple sound effect playback
oTouch CS15 once to start loop play one of the four pre-recorded sound
effects; touch CS15 again to stop the playback.
Voice Record and Playback
oTouch CS12 + CS9 then release CS9 to start recording (CS12 is irrelevant
after recording starts)
oTouch CS9 to stop recording
oNow every touch of CS9 will playback the recorded sound effect
Playback volume adjustment
oSwipe the bottom CS0-7 row to increase (from CS7CS0, Left to right) or
decrease (from CS0 CS7, right to left) the playback volume, during
playback, or when there is no active playback.
oThe RGB LED turns green during playback. The brightness of green color
varies indicating volume change.
Voice Recognition (VR)
oVR is constantly running when device is idle. In this idle state, the device
only responds to the leading command which is “Fruit_Color”.
oOnce the leading command “Fruit_Color” is recognized, the RGB LED
will be turned off indicating the device is waiting for further fruit
commands: “apple”,“banana”,“blueberry”, “kiwi”,“orange”or
“peach”.
oWhen the RGB LED is off, saying the fruit command to the device will let
the RGB LED show the corresponding color for ~3 seconds; then the RGB
LED will revert back to off state. In this off state, saying “Fruit_Color”
again will make the system back into idle, indicated by RGB LED randomly
changing color.
