Implementation interface SPI on NX2LP over GPIF

Hello!

I read AN14558 "Implementing I/O Bit-Bang SPI Interface with EZ-USB FX2LP ™", it says that it is possible to implement SPI GPIF. Does anyone have a ready solution for the implementation of the SPI interface using the GPIF? Can I set the GPIF to work with NAND flash memory and the SPI Flash memory?

Thank you?

Hi,

We don't have any example to show you how to implement SPI interface over GPIF.

We can implement SPI using GPIF but it can perform either read or write operation at a time. It will not be able to read data coming on MISO while writing data on MOSI.

Please let me know the exact application requirement so that we can help you in suggesting alternate solutions to your problem.

Thanks,

Sai Krishna.
