2.4 OTHER DEMO CODE EXAMPLES

The starter kit software CD includes other demo code examples.

The SASK Record Play Demo with Intro Code Example demonstrates the low-cost

speech capture and playback option. It uses the dsPIC DSC 12-bit ADC to capture

speech samples. The data is stored in the serial Flash memory. The application then

uses the Output Compare module in Pulse-Width Modulation (PWM) mode to generate

a PWM signal representing the speech signal.

The SASK Intro Speech Prog code example can be used to program the introductory

message into the serial Flash. This is useful in a case where the entire serial Flash has

been erased and it is desirable to set up the introductory message again.

Note: Jumper J6 should in the OCPWM position to use this demo.

Note: The SASK Intro Speech Prog code example performs a full chip erase on

the serial Flash. In order to prevent accidental serial Flash chip erase when

the board is taken in and out of Reset, erase the dsPIC33F program Flash

via MPLAB IDE after the running the SASK Intro Speech Prog code

example. Refer to the readme.txt files in the project folder for more

details.
