NAME ^

FTDI::D2XX - Perl extension for interface to FTDI d2xx library (tested with version 0.4.16 linux, see readme for windows)

SYNOPSIS ^

  use FTDI::D2XX;
  my $FTD = FTDIId2xx->new(0); # open device with id 0
  unless( $FTD->FT_Write(\@data,@data,$written) == FT_OK ) {
        print "Write error";
  }

  # not needed due to destructor: $FTD->FT_Close();

  OR

  use FTDI::D2XX;
  my $handle;
  FTDI::D2XX::FT_Open($handle,0); # open device with id 0
  unless( FTDI::D2XX::FT_Write($handle,\@data,@data,$written) == FT_OK ) {
        print "Write error";
  }
  FTDI::D2XX::FT_Close($handle);

DESCRIPTION ^

This is an interface to the d2xx library from Future Technology Devices International Limited (FTDI). The basic idea for this interface comes from the Win32::FTDI:FTD2XX perl module. It was started as a port from the Windows module to linux but it became a completly new implementation. This modules does not contain any code from the Win32::FTDI:FTD2XX module. Thanks for the source code from Scott K MacPherson as a starting point.

The mainly all standard functions of the D2XX library excluding the FT_W32_* functions are implemented. The functions can be used as in the D2XX documentation or in a object oriented way.

STATUS

This is a pre-alpha version. Only small tests have been done by using a test script included in this package and an FT2232L IC. Testers are welcome.

EXPORT

FT_OK is the only default export.

FUNCTIONS and METHODS ^

The module provides a new constructor which connects a ftdi handle with the module by using bless. Therefore all FT_functions can be called as a method if a handle is the first parameter.

The following list describes only the differences to the original implementation by FTDI. All functions, except new() returns the status of the operation. Parameters marked by * will be changed by the function. Mosts of the * marked parameter are only feedback from the library. These scalars are not initialized by the xs code - result: $device->FT_GetBitMode($mode) works but not $device->FT_GetBitMode(\$mode) because the library generates a new variable instead of using the existing one.

New

Parameters: deviceID [mode]

Returns: Object Reference of the Object FTDI::D2XX

Purpose: Open a FTDI device and return the handle as a object reference. This function behaves like FT_Open with one parameter and like FT_OpenEx with two parameters.
