Hi,

I am working on a project about fx3 recently.FPGA generates interrupt signal to FX3 through GPIO.Fx3 receives the interrupt signal and then reads the register of FPGA.I don't know much about FX3.What should I modify about GPIO based on the AN65974?

Thanks,

Hi,

Please refer to the firmware example found at  C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\serialif_examples\cyfxgpioapp

The above example can be used as a base to configure a gpio as an interrupt and define a call back function to handle it.

You will need to define the code for the required function( read register of FPGA) in the callback function.

Regards,

Yashwant
