Test the FrontPanel Interface

After configuring the FPGA with your desired bitfile, it’s a good idea to test that FrontPanel is enabled in your FPGA configuration using IsFrontPanelEnabled(). Testing FrontPanel after configuration is a good way to check for a variety of issues. For example,

• It assures that the bitfile was found and transferred to the device.
• It assures that the bitfile has proper host interface pin mappings.

C/C++

  OpalKelly::FrontPanelDevices devices;
  auto dev = devices.Open();

  okErrorCode error = dev->ConfigureFPGA("example.bit");
  // It's a good idea to check for errors here!!

  // IsFrontPanelEnabled returns true if FrontPanel is detected.
  if (dev->IsFrontPanelEnabled()) {
      std::cout << "FrontPanel host interface enabled.\n";
  } else {
      std::cerr << "FrontPanel host interface not detected.\n";

C#

  okCFrontPanelDevices devices = new okCFrontPanelDevices();
  okCFrontPanel dev = devices.Open("");

  string bitfile = "example.bit";
  okCFrontPanel.ErrorCode error = dev.ConfigureFPGA(bitfile);
  // It's a good idea to check for errors here!!

  // IsFrontPanelEnabled returns true if FrontPanel is detected.
  if (dev.IsFrontPanelEnabled()) {
      Console.WriteLine("FrontPanel host interface enabled.");
  } else {
      Console.Error.WriteLine("FrontPanel host interface not detected.");

  dev = devices.Open()

  error = dev.ConfigureFPGA("example.bit")
  # It's a good idea to check for errors here!!

  # IsFrontPanelEnabled returns true if FrontPanel is detected.
  if dev.IsFrontPanelEnabled():
      print("FrontPanel host interface enabled.")
  else:
      print("FrontPanel host interface not detected.", file=sys.stderr)Code language: PHP (php)
