            Please use any of the example firmware present in the FX2LP DVK as a reference for creating and building you project. The example firmware in DVK package contains the required framework file fw.c which initializes device in a proper sequence so as to enumerate the device in the host PC and perform the required operation.


            Refer to the EZ-USB Development Kit User Guide present in the FX2LP DVK package Chapter 6: FX2LP Code Development Using the EZ-USB Framework for more details regarding the developing the firmware for FX2LP, which is a simple process when the fw.c file is used.

            The functional code can be put into the TD_Init() and TD_poll() sections of the firmware file.


            For details regarding the FX2LP registers and snippet of codes for the respective functions can be found in the EZ-USB Technical Reference Manual.
