After you soldered your headers and mics, it's time to try and get some sound in and output from your teensy devices! Here is a short how-to, partially summarizing what we did in the last online session.

  1. Installing Arduino IDE and Teensyduino: https://www.pjrc.com/teensy/td_download.html
  2. Opening and programming the example patch
opening the example test patch

If you are having problems connecting your teensies :( read through the following sections:


  1. check out the teensy web ide patches: https://www.pjrc.com/teensy/gui/
    • add the following nodes from the gui:
      1. from "input" add "i2s"
      2. from "output" add "i2s"
      3. from "control" add "sgtl5000"
Audio System Design Tool "Audio through patch"
  1. Click the export button to generate the setup code for your teensy and paste it in your Arduino IDE patch!
  2. In the setup routine of the arduino IDE you need code to choose the microphone port and audio levels. It should look more or less like this:
void setup() {
  // Audio connections require memory to work.  For more
  // detailed information, see the MemoryAndCpuUsage example
  AudioMemory(8);
  // Enable the audio shield and set the output volume.
 
  sgtl5000_1.enable();
  sgtl5000_1.inputSelect(AUDIO_INPUT_MIC);
  sgtl5000_1.micGain(36); //from 0dB 40dB
  sgtl5000_1.volume(0.8); // from 0.0 to 1.0 // 0.8 standard
}
  1. Press upload and compile the patch.
