STEVAL-ICV001V1

STEVAL-ICV001V1 Sound/voice playback demonstration board based on the ST7LITE02Y0 Data Brief Features 1% calibrated on-chip RC oscillator Low-voltage detector (LVD) on chip Small footprint Low-power operation Supports lower density serial Flash if fewer messages needed Order of filter can be reduced for further cost savings Description This board demonstrates how to add audio playback to any application using a general- purpose ST7 microcontroller. The audio player demonstration board reconstructs audio signals STEVAL-ICV001V1 through the PWM of the ST7FLITES2 microcontroller, and a serial Flash is used to store the audio data in a binary file format. Once the data is stored, the microcontroller reads it through an SPI interface and generates the sound using the PWM feature. A sixth order low-pass filter removes any unwanted high-frequency components from the signal before passing it to a speaker.
