14. GPIF™ II Designer
GPIF™ II Designer provides a graphical user interface to configure the processor port of EZ-USB
®
FX3 to connect to external devices. The interface between EZ-USB
®
FX3 and the external device
can be specified as a state machine, and the GPIF-II Designer tool will generate the register
configuration in the form of a header file that can be readily integrated with the FX3 firmware
application using the FX3 API library. Please refer to the GPIF II Designer User Guide for more
details on the tool.
The FX3 SDK includes the GPIF-II configuration header files for various Slave-FIFO modes. Please
see the Getting Started Guide and the Application Note AN65974 - Designing with EX-USB FX3
Slave FIFO Interface for details on using these configuration headers. Please contact Cypress USB
support team for any queries on GPIF-II configuration.
