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.

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.

See Figure 1 on the back of this page to view the Speech Playback PICtail Plus 
Daughter Board schematic.
