OMAP-L138 GPIO Interrupt

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

I am using Code Composer Studio/C Language to program OMAP-L138, trying to generate an GPIO Interrupt at a frequency ~1MHz. I have looked over the sample C libraries functions, as well as the L138 Manual, but I found them confusing and still don't know how to do so. Are there any sample codes I can look at? More particularly, I don't know exactly how to set the frequency of interrupt and how to write to/read from a register in L138.

Thanks

Hi,

I think, looking at the quickStart_rCSL below would be a good reference code for GPIO interrupts

Thanks & regards,

In addition to Sivaraj's suggestion, I would like to add the following.
We have also some GPIO interrupt based example code in starterware package.
