Kinetis K60 Tower FTM Capture Mode not working ... Please Help !

proberts — Sat, 14 Jul 2012 21:07:21 GMT

I've set up FTM1 Channel 0 to Capture using FTM1_C1V using the capture input pin at PTA13 (FTM1_CH1). I'd like to interrupt on both edges. My interrupt is enabled. I have placed a breakpoint inside the generated function TU2_OnChannel0.

I am using FTM0 to generate a 60 Hz square wave by toggling a GPIO from within the ISR. I have hard-wired this GPIO to location A20 on my Freescale proto board for my K60 tower. My schematic shows that A20 is connected to PTA13. I have connected a scope and can see the 60Hz square wave plain as day on location A20 (which I really hope is connected to PTA13.)

I have spent a lot of time juggling things around to get my debugger to go to the breakpoint, with no luck. Attacvhed is my PE screen shot.

Hi,

Unfortunatelly, your screenshot does not show configuration of the capture component.

Could you please post a sample project showing the problem or at least ProcessorExpert.pe file (it contains configuration of all components).

best regards
