P _Description
lete ^{This board demonstrates how to add audio}
o playback to any application using a general-
s _{purpose ST7 microcontroller. The audio player}
b _{demonstration board reconstructs audio signals}
O _{through the PWM of the ST7FLITES2}
- _{microcontroller, and a serial Flash is used to store}
t(s) ^{the audio data in a binary file format. Once the}
data is stored, the microcontroller reads it through
c _{an SPI interface and generates the sound using}
u _{the PWM feature. A sixth order low-pass filter}
rod ^{removes any unwanted high-frequency}
components from the signal before passing it to a
Obsolete ^{P speaker.}
