External interrupts on DSK6455

Manuel Fernandez-Ros

Hello

I'm using a DSK6455 + 5-6K interface + ADS1274EVM and ADS1282EVM boards, and I'm working with SPI protocol.

The EVM boards use the interrupt on pin J5.15. I think that this pin is wired via 5-6K interface to the GP(6) pin in the 6455 CPU. Please, can you confirm this?

The interrupt GP(6) has asscociated the event number 57. Please, can you confirm this?

Well, my last question, must I program the GPIO module to prepare the external interrupts or is it programmed in the DSK6455 board?. If not, have you got any example?

Thanks and best regards.

Manuel Fernández Ros.

    Manuel,

    This sounds like a very capable system you have put together. It should allow you to build a powerful application on it.

    This is a bit challenging to get several boards working together. But I trust that you do have all the documentation on each one and on each of the major components of them, like the C6455 on the DSK6455. Those documents will confirm how things are connected.

    To your last question: Yes, you must program everything to make this work properly. There may be Board Support Libraries and Chip Support Libraries that will have API functions you can use and examples that you can follow. Have you installed the BSL and CSL for the DSK6455?

    Regards,
    RandyP

    Hello RandyP

    Thank you for your quick response. Now, I'm working with external interrupts.

    Best regards.
