and libraries used in the project:

Remember - they are dirty, daily updating, may not work properly

  • The ARD-AUDIO-DA7212 is an ‘audio shield’ that can be used with a number of MCU development platforms due to its compatibility with the Arduino™ R3 pin layout.
  • The audio shield can be used with commercially available development platforms such as Freescale ‘Freedom’, Intel ‘Galileo’, Microchip ‘chipKIT’ and Arduino.
  • Introduction page for this board
  • Product page on Digi-Key(1564-1021-ND)
  • 5V power for speaker
  • 3.3V for I2C/I2S and headset mic bias
  • 1.8V(by on-board LDO) for internal analog
  • I2C access by address 0x34(8bit)/0x1A(7bit)
  • onboard I2C 2.2k pullups (R19 and 20; may be too strong pullup in case of multi slaves)
  • I2S
  • stereo AUX input
  • MIC1 R-ch input used for headset mic
    • (alternate) MK1 MIC2 R-ch input used for onboard MEMS (such as 423-1138-1-ND at digikey, not assembled by default)
  • MIC1/2 L-ch is accessible by testpads
  • Every part is gain controllable
    • Microphones1/2 L/R
      • 3bits range
    • AUX L/R
      • 6bits range
    • ADC/DAC L/R
      • 7bits range
    • Headphone Out L/R
      • 6bits range
    • Speaker Out
      • 6bits range
  • J3 microSD card socket Molex 0492250821/WM3295CT-ND
    • not assembled by default
    • Need to short R14 ~ R17 for use
