PPI & Timer counting PWM Pulses

[motters]

Hi All,

I'm trying to generate an interrupt on the X PWM's falling edge. My idea was to setup the PWM and count the number of falling edges using PPI & a timer / counter. Once the counter reached value X it would generate an interrupt.

For some reason PPI is not incrementing the count on the timer, even though the GPIOe event is being generated (dummy handler is triggered).

See https://gist.github.com/motters/f17a2043ee3fd42481ddf8d07b2d00f9 for the implementation. 

I can post the code on here, just though Gist is easier to view.

Cheers all.

This is now solved, few small issues with enums mainly. 

I've updated the Gist for anyone else who's having an issue.
