Driving LCD on BOOSTXL-EDUMKII using SPI

Other Parts Discussed in Thread: MSP-EXP432E401Y, BOOSTXL-EDUMKII

Hi all,

I am trying to interface LCD on BOOSTXL-EDUMKII with MSP-EXP432E401Y LaunchPad, using SPI.

To do that, I made pin connection as follows:

                                             BOOSTXL-EDUMKII           MSP-EXP432E401Y         

      Pin Function                   Plug-in Connection              Plug-in Connection

    LCD SPI Clock                      J1.7                                 PD3(J1.7)  SSI2CLK

    LCD SPI MOSI                      J2.15                               PD1(J2.15) SSI2XDAT0

    LCD SPI Chip Select            J2.13                                PD2(J5.2)  SSI2Fss

    LCD Reset Pin                      J2.17                                PE4(J1.2)  SSI1XDAT0

    LCD Register Select             J4.31                                PC6(J1.5) EPI0S5

But, these pin connection does not work properly.

Appreciated in advance any advice/suggestion for the pin connection, specially, the pins in 432E LaunchPad against LCD Reset Pin and LCD Register Select.

    Hi,

    I checked on the BOOSTXL-EDUMKII board. This board is recommended to work with MSP432P401R and TM4C123. If you want to use this board with MSP432E301Y, you might need to change the pin connection instead of using the plug in connection.

    Best regards,
