FX3 spi mode

Hello,

can i use UART_RTS,UART_CTS,GIPO[26],GIPO[27] as spi signals in FX3?

I have found example in the path C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\serialif_examples\cyfxusbspigpiomode.can i implement the spi controller using this example and above gpios?

thank you.

Hi,

I had understood your question wrongly.

CyU3PMemSet ((uint8_t *)&io_cfg, 0, sizeof(io_cfg));

io_cfg.isDQ32Bit = CyFalse;

io_cfg.s0Mode = CY_U3P_SPORT_INACTIVE;

io_cfg.s1Mode = CY_U3P_SPORT_INACTIVE;

io_cfg.useUart = CyTrue;

io_cfg.useI2C = CyFalse;

io_cfg.useI2S = CyFalse;

io_cfg.useSpi = CyFalse;

io_cfg.lppMode = CY_U3P_IO_MATRIX_LPP_DEFAULT;

As per the reference above, UART_RTS and UART_CTS i.e GPIO[53], [54] alongwith GPIO[26],[27] can be used as software (bit banging) SPI signals.
