    These are the given examples:

    1. example_mibspi_trigger_tick.c
    2. example_mibspiDma.c

    I would like to start with basic, Could you please provide us basic example on how to transmit and receive data to and from external device like port expander, display drivers etc.

    Hi Rahul,

    I suggest to use standard SPI example as the starting point for your study: example_spi_Master_Slave.c

    5340.example_spi_Master_Slave.c

    Hello Rahul,

    The hardware connection is listed in the files:

    *   PIN Connections must be as Below
    *     ---------------         ---------------
    *     SPI1 ( Master )          SPI2 ( SLave)
    *     ---------------         ---------------
    *     SIM0             --->    SIMO
    *     S0MI             <---    SOMI
    *     CLK              --->    CLK
    *     CS0              --->    CS0
    *
    HALCoGen Configuration:
    *  ------------------
    *  GUI configurations
    *  ------------------
    *  1) Driver TAB
    *       - Select SPI2
    *       - Select SPI1
    *  2) VIm Channel 0-31
    *       - Enable SPI2 Level 0 and Level 1 channels.
    *  3) SPI2 TAB
    *       - SPI2 Global SubTAB
    *           - Uncheck Master Mode
    *           - Uncheck Internal Clock
    *       - SPI2 Port SubTAB
    *           - Uncheck DIR for CS 0
    *  3) SPI1 TAB
    *       - Have it default
    *  4) Generate Code.
