    Hi  Mark,

    All the examples we have are working in full duplex mode. The halcogen has couple SPI or MibSPI examples:

    To configure the SPI as half-duplex, you need t write 1 to HDUPLEX_ENAx of SPIFMx register:

    In half-duplex mode, the SIMO is used as RX pin for master mode, and TX pin for slave mode.

    For full-duplex mode, the SIMO is master TX and Slave RX.
