// Three types of output may be used, by configuring the code below.
|
|
//
|
|
// 1: Digital I2S - Normally used with the audio shield:
|
|
// http://www.pjrc.com/store/teensy3_audio.html
|
|
//
|
|
// 2: Digital S/PDIF - Connect pin 22 to a S/PDIF transmitter
|
|
// https://www.oshpark.com/shared_projects/KcDBKHta
|
|
//
|
|
// 3: Analog DAC - Connect the DAC pin to an amplified speaker
|
|
// http://www.pjrc.com/teensy/gui/?info=AudioOutputAnalog
|
|
//
|
|
// To configure the output type, first uncomment one of the three
|
|
// output objects. If not using the audio shield, comment out
|
|
// the sgtl5000_1 lines in setup(), so it does not wait forever
|
|
// trying to configure the SGTL5000 codec chip.
|
|
//
|
|
// The SD card may connect to different pins, depending on the
|
|
// hardware you are using. Uncomment or configure the SD card
|
|
// pins to match your hardware.
|
|
//
|
|
// Data files to put on your SD card can be downloaded here:
