GPIO not functioning as desired

Rupesh Mehta

Hey

When i tested the sample GPIO input program ( GPIO11 connected to GPIO4 with a jumper),it gave a successful result

when i removed the jumper and tested it,it still gives a successful result !

Actually was working to get a LCD module interfaced with the VC5505 ezDSP through GPIO pins.

Thanks,

Rupesh

Hi,

I am trying to do the same simple program, creating a GPIO interrupt between GPIO 4 and 11 but i can't get it. It never goes inside ISR.

How do you do that?

Thanks

Hi,

Did you try to looking at the GPIO examples in the C55xx CSL example package. These examples use interrupts and could help resolve your issue.

You can download the C55xx CSL package from the below lonk.

Hope the above helps.
