Installing D2XX Drivers
Return to Introduction  Previous page  Next page
Download the driver from the D2XX Drivers section of the FTDI web site and save it to the hard disk. The driver is provided in disk image (.dmg) format. Mount the disk image by double clicking on the PPC D2XX0.1.0.dmg icon for Power PC users or the Universal D2XX0.1.0.dmg icon for Intel Mac users.

·Start a Terminal session (Go > Applications > Utilities > Terminal)  

·Copy libftd2xx.0.1.0.dylib to the /usr/local/lib directory (cp Desktop/D2XX/bin/libftd2xx.0.1.0 /usr/local/lib)  

·Change directory to the /usr/local/lib (cd /usr/local/lib)  

·Create a symbolic link to the library (ln -sf libftd2xx.0.1.0.dylib libftd2xx.dylib)  

Samples written in C are provided to show how to use the library and verify the installation. These are command line based applications that must be executed from the Terminal window. To compile and run the samples perform the following steps (these assume you have copied all of the distribution files to the desktop and installed the library as per the Installation section above):

·Open a Terminal window (Go > Applications > Utilities > Terminal).  

·Change directory to the root samples directory (cd Desktop/D2XX/Samples).  

·Build the samples by typing "make" then return. If you have issues at this stage revisit the installation section above to ensure the library is correctly installed. Read the error messages and try to determine the source of the problem. If you still have issues then contact support detailing your issue with as much information as possible.  

·To run an application, have a suitable FTDI device with default VID (0x0403) and PID (0x6001) and change to the Simple directory (cd Simple) then type "./simple" followed by return (make sure the dot and the forward slash precede the simple command).  

·If you have issues at this stage then consult the troubleshooting section later in this document. If the troubleshooting section doesn't help then contact support with your problem details.
