Description
The goals of the SAM3S-EK Phone Demo are to get familiar with both the Analog-to-Digital Converter (ADC) and the Digital-to-Analog Converter Controller (DAC).
Therefore, in the first hands-on part, you will convert an analog signal coming from the microphone to a digital one. This is the sound recording part.
Then, in the second hands-on part you will convert the music digital data to an audio stream. This is the audio play part.
Finally by combining these two parts you will be able to record and play back sound. At the end, as a demo you can do a phone communication using Skype for example or any other communication tools. Depending on the comparison result, a dedicated bitmap image will be displayed on the LCD screen.
