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.
