Speech Playback PICtail? Plus Daughter Board Info Sheet

Speech Playback PICtail™ Plus Daughter Board
Overview
The Speech Playback PICtail™ Plus Daughter Board is a demonstration board for
evaluating speech playback algorithms that operate on Microchip’s PIC® microcontrollers
or dsPIC® Digital Signal Controllers. It is an expansion board that is compatible with
many of the PIC16 and PIC18 development boards employing a PICtail connector and
with the Explorer 16 Development Board using the PICtail Plus connector.
Features
-
3V or 5V operation
Potentiometer for volume control
4th order Low Pass Filter
Mono output via on-board speaker or stereo output via headphone connector
Shutdown control of power amplifier
On-board 256 Kbit SPI Serial EEPROM for voice storage
Getting Started
To get started, an HPC Explorer Board with a PIC18F87J10 or PIC18F8722
microcontroller, or an Explorer 16 Development Board with a PIC24F microcontroller
is needed. The headers on the Speech Playback PICtail Plus Daughter Board allow
insertion in the development boards in only one orientation. Projects for both PIC18 and
PIC24F devices can be downloaded from the Microchip web site (www.microchip.com).
The demonstration software implements a talking thermometer using the TC74
temperature sensor on the HPC Explorer Board or the TC1047A temperature sensor on
the Explorer 16 Development Board.

Daughter Board schematic.
