Detailed Description

This library is a highly modified version of Ladyada's Wave Shield library. I have made many changes that may have introduced bugs.

WaveHC class

Macro Definition Documentation

◆ OPTIMIZE_CONTIGUOUS

#define OPTIMIZE_CONTIGUOUS 1

If nonzero, optimize the player for contiguous files. It takes longer to open a file but can play contiguous files at higher rates. Disable if you need minimum latency for open. Also see open by index.

◆ DVOLUME

#define DVOLUME 0

Software volume control should be compatible with Ladyada's library. Uses shift to decrease volume by 6 dB per step. See DAC ISR in WaveHC.cpp. Must be set after call to WaveHC::create(). Decreases MAX_CLOCK_RATE to 22050.

◆ RATE_ERROR_LEVEL

#define RATE_ERROR_LEVEL 2

Set behavior for files that exceed MAX_CLOCK_RATE or MAX_BYTE_RATE. If RATE_ERROR_LEVEL = 2, rate too high errors are fatal. If RATE_ERROR_LEVEL = 1, rate too high errors are warnings. If RATE_ERROR_LEVEL = 0, rate too high errors are ignored.

◆ PLAYBUFFLEN

#define PLAYBUFFLEN 512UL

Buffer length for Arduinos other than 168.

◆ MAX_BYTE_RATE

#define MAX_BYTE_RATE 88200

Maximum SD read rate for 512 byte buffer and contiguous file

◆ MAX_CLOCK_RATE

#define MAX_CLOCK_RATE 44100

maximum DAC clock rate
