Interrupt tutorial?

Gregory Scharr

I'm trying to get the ezdsp usb stick to interrupt when a gpio goes high, but I can't seem to figure it out. Are there any tutorials on how to use interrupts that I could reference?

Gregory,

Please take a look at this E2E thread with a step-by-step process of creating a GPIO interrupt.

Hope this helps.

I should have specified earlier: I'm using the C5505 board. Will that library still work even though it is it is for the C5515?

There is a board support library available for ezdsp usbstk 5505 here: http://support.spectrumdigital.com/boards/usbstk5505/revd/

The usbstk5505 BSL seems to incorporate the C55x CSL. The tutorial seems to take code from usbstk5515_gpio.c. The same functions are available in usbstk5505_gpio.c, but it includes a CSL header and makes function calls defined in csl_gpio.c. They should accomplish the same task, but will look a little different.

Hope this helps.
