MSP-EXP432E401Y: SD-Card connection to MSP432

Part Number: MSP-EXP432E401Y
Other Parts Discussed in Thread: TIDM-TM4C129SDRAMNVM, MSP432E401Y

Hi,

i search for Source code / Hardware connection / Demo board for contacting an SD-card with MSP432

is it better to use the legacy SPI Mode or the newer SDCard interface (DAT0..3 lines) ?

Can the driverlib handle SPI mode?

Is this connection correct?:

SSI0CLK -> 5-SCLK

SSI0TX -> 3-DI

SSI0RX <- 7-DO

SSI0FSS (or any other pin) -> 2 - ChipSelect

Thank you

    Hello Simon,

    The MSP432E401Y device uses the SPI interface for a SC Card. You may refer to the TIDM-TM4C129SDRAMNVM for suitable connections as per the schematics. It is an equivalent reference design applicable to the MSP-EXP432E401Y LaunchPad.

    However the driverlib does not support the SD Card function. All such examples have been moved to the no-RTOS or RTOS framework, which allows for easy migration between SimpleLink devices. Such an example can be found at
