If you want to use Processor Expert Init and LDD components (without SDK) you can use DMAChannel_LDD and Init_SPI components (SPIMaster_LDD component does not support eDMA). You must set one DMAChannel for SPI receive request and one DMAChannel for SPI transmit request for the selected SPI device. The Init_DSPI must be initialized for using DMA. But you must implement all DSPI functions by yourself.</P><P>If you create a Processor Expert with Kineits SDK 1.1, you can use fsl_dspi component, set the requested DSPI mode (e.g. Master) and use DSPI_DRV_Edma... methods to use DSPI with eDMA.</P><P></P><P>Best Regards,</P><P>Marek Neuzil</P><P></P><P><BR /> </P></BODY></HTML> Tue, 17 Feb 2015 14:06:32 GMT https://community.nxp.com/t5/Processor-Expert-Software/How-do-I-Configure-DSPI-with-eDMA/m-p/352636#M2696 marek_neuzil 2015-02-17T14:06:32Z
