Hide
In the file SPIMSP432E4DMA.c the function spiPollingTransfer enables the SSI, performs the transfer and then disables the SSI. As a result the SSI module gets stalled and the clock does not transition. To rectify the same a check for SSIBusy must be added before SSIDisable is called

    while(SSIBusy(hwAttrs->baseAddr));

    SSIDisable(hwAttrs->baseAddr);

In the file SPIMSP432E4DMA.h the define for the SSI1FSS is incorrect. The current file has the define as

SPIMSP432E4_PB4_SSI0FSS

which must be

SPIMSP432E4_PB4_SSI1FSS
