Detailed Description

RecNPlay Click example.

Description

This application demonstrates the processof recording a message and playing it back.

The demo application is composed of two sections :

Application Init

Initializes SPI interface in proper mode and performs all the necessary commands to put the device in proper working mode (chip reset, chip power up, chip erasing, clock configuration).

Application Task

Performs the chip configuration for recording message via microphone, then records a message for 8 seconds to specified memory location. After that, it reads the recorded message address with message length and then plays the recorded message. When playback is done it erases the recorded message from memory. Afterwards, it repeats all the operations every 10 seconds.

note: The ISD3900 must be properly configured to work in record mode every time when user wants to record a message. When user wants to play a recorded message, then ISD3900 must be properly configured, but now to work in play mode.
