Hi, all.

I am a newman of FX3, and i using SuperSpeed Design Examples V1.2\FX3 Firmware Projects\GPIF_Example10 to set up a 8bits parallel communication with one slave mcu.

for now data send out from FX3 is ok, but i don't know how to trigger FX3 read procession.can any one help me out?

i have tried to set up the signals follow the GPIF design timing but the FX3 do not trigger a read procession.

where is the interface signal specification? i want to konw the signals timing.

and is there any files for good understanding of the GPIF state machine?

Tks

Hi Tony,

AN87216 has both Master and Slave firmwares. One FX3 acts as a Master and other slave. So, you can refer to the GPIF state machine implementations in both the cases and see how the reads and writes are managed.
