Buzzer, Stereo Jack and UART - muneeb-mbytes/FPGABoard_edgeSpartan6 GitHub Wiki

Buzzer:

  • The Edge board contains piezo buzzer( an electronic device that is commonly used to produce sound) interface with FPGA through transistor.
  • 5v Buzzer is used provide alert tone (where you can expect its best performance).
  • Note: To enable Buzzer, place jumper at Enable and centre pin of J6. To disable power, place jumper at Disable and centre pin of J6.

Stereo Jack:

  • Stereo Jack is the port into which you plug your headphones.
  • Stereo Audio Jack with low pass filter is connected on the FPGA I/O lines on the EDGE Board. Stereo Jack provides delta sigma audio output.

UART:

  • The EDGE Board includes FT2232 IC acts as USB UART Bridge to communicate board with windows PC COM port interface.
  • The UART Transmitter and Receiver lines of FTDI that is Future Technology Device International which is a USB to serial converter allowing simple connection to USB chip is directly connected to the Spartan6 FPGA I/O pins for USB UART Communication.

Note: the below shown is the image of FTDI IC present on the FPGA Edge board.
