DM36x GPIO interrupt level trigger possible?

Hao Liu48112

would like to use GPIO interrupt on DM36x but realized it only supports edge trigger. i am using a SPI/Uart IC which generates level interrupt. Is there any way or reference design for DM36x to support level trigger for GPIO interrupt? either internally or via external logic. thanks a lot.

I checked this with PSP team. They told me DaVinci devices does not support GPIO level trigger interrupt.

Hi Edward, thank you for your info.

I am thinking a way to convert level trigger signal to edge trigger signal for DM368. Is there any external logic/circuit design as reference for this conversion? Thanks a gain.
