Hi.

I would like to know that CY3685 can support or emulate SPI i/f by GPIF?

If anyone has experiences about that, please tell me.

Regards.

Shigeto

Hi Shigeto,

I guess you are talking about CY3684 (FX2LP DVK), not CY3685 (NX2LP DVK).

Although the 8051 contains two UARTs, it does not include a hardware SPI (Serial Peripheral Interface) unit.

However it is possible to implement an SPI master using one of two methods.

Kindly refer to the AN14558 - Implementing an SPI Master on EZ-USB® FX2LP™

Hi Hirotaka.

Sorry, CY3685 is typo.

Any way I will check the AN1458.

Thank you for your cooperation.
