Package cbsw.adept.xilinx

Class XilinxDjtg

  • All Implemented Interfaces:
    java.awt.event.ActionListener, java.util.EventListener
    public class XilinxDjtg
extends java.lang.Object
implements java.awt.event.ActionListener

    Implements Xilinx FPGA programming and other functionality through the Digilent Adept DJTG interface.

    The programming function should work for both Series7 FPGAs and Spartan6 and probably others.

    Other functions, such as XADC access is only available on some devices.
