Introduction

This module features the MSGEQ7 graphic equalizer display filter.It will give your arduino ears. Sound is broken down into seven frequency bands and the peak level for each band can be read. The seven frequencies measured are as follows 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz. This module can be used to create sound visualizers, detect patterns in music or add sound activation to your microcontroller.

CVAVR Code:
using atmega128 clock 16Mhz , usart0 9600 baud rate , timer1 scale clock 1024 , adc. formula timer1 when use clock freq 16Mhz

Ttimer1 = Periode Timer1 TCNT1 = Register Timer1 N = Scale clock 1, 8, 64, 256 dan 1024 Tosc = Periode clock Fosc = Frekuensi clock cristal

Tosc = 1/Fosc Tosc = 1/16Mhz =

Ttimer1 = Tosc * 65536 - TCNT1 * N 1 second = * 65536 - TCNT1 * 1024 TCNT1 = 49911 TCNT1 = C2F7 in hex <-- this use in //Timer 1 overflow interrupt service routine

Clock value = Fosc/N Clock value = 16Mhz/1024 = 15,625 kHz <-- this use in clock value timer1

Can use timer0 or other timer with each formula
