Hi all, first of all sorry for inconvenience from me. i'm trying to interface imxrt1170 with WILINK1807 wifi chip over the sdio protocol .here i have illustrated the wilink 1807 and rt1170 connection's prototype.
rt1170 wilink1807
SDMMC->DATA0 SDIO->DATA0
SDMMC->DATA1 SDIO->DATA1
SDMMC->DATA2 SDIO->DATA2
SDMMC->DATA3 SDIO->DATA3
GPIO10->12 RST/Enable
GPIO10->13 IRQ
i need to set the GPIO10->13 as SDMMC card interrupt.
i have gone through the rt1170's RM. The DATA1 line is default interrupt pin.
i hope the sdmmc stack designed for default parameters .
my questions
how can i disable default interrupt related functionalities?
can i add the any GPIO's interrupt for sdmmc stack for further works?
Hello
Hope you are well.
To disable the interrupts from certain handled you might want to use "DisableIRQ()" Regarding USDHC you can use "USDHC_DisableInterruptStatus(), USDHC_DisableInterruptSignal()"
GPIO interrupts can be added with "GPIO_PortEnableInterrupts()"
If you have more questions do not hesitate to ask me.
Best regards,
Omar
