GPIO DMA Event

GPIO DMA Event

This question is answered

Hello,

Are there any functions related to generating DMA events from GPIO input pins? I found in gpio.h only for setting interrupts. The Technical Reference Manual of C6748 section "19.2.11 EDMA Event Support" doesn't say anything just "The GPIO peripheral may provide synchronization events to the DMA controller."

Thank you in advance,

David.

    Hi Sujith,

    I cannot use the technical reference manual either, any documentation available regarding this matter then?

    Best regards,

    David,

    The GPIO interrupts definitely can be used to drive EDMA transfers.  The relevant event IDs (ex. EDMA3_CHA_GPIO_BNKINT0) are defined in the edma_event.h header file.  For C6748, you should find this file in the include/c674x/c6748 folder.  I recommend reviewing one of the existing example applications that uses EDMA, such as examples/evmC6748/uart_edma, to understand how to setup EDMA using the StarterWare APIs.
