Babyphone audio playback

January 21st, 2012 · No Comments · Uncategorized

The final circuit has been built inside the phone enclosure, including amplifiers for the speaker and the microphone.

Playback and record modules are developped an tested but the application code only supports playback for the moment.

Next I need to improve the matrix keyboard driver to allow multiple key detection to trigger the record of a new sound. The key combination should be hard enough to prevent the boy from erasing existing message.
