Detailed Description

The MSGEQ7 is an 7-band audio filter.

The band frequencies are centered around: 63Hz, 160Hz, 400Hz, 1000Hz, 2500Hz, 6250Hz, 16000Hz. After a pulse on "reset_gpio" pin, a peak detector for each band is multiplexed on the pin "signal_out" at each pulse on pin "strobe_gpio".

Constructor & Destructor Documentation

MSGEQ7()

MSGEQ7::MSGEQ7	(	uint	strobe_gpio,
		uint	reset_gpio,
		uint	signal_out )

Construct a new MSGEQ7 object.

Parameters

strobe_gpio	the gpio connected to strobe
reset_gpio	the gpio connected to reset
signal_out	the gpio connected to the analog multiplexed peak detector
