Hi Jason,
Attached is example using KDS_3.0+KSDK_1.3 for FRDM-K64F that is using GPIO, FTM0, and FTM3.
FTM0 PWM duty cycle is going from 0-100 to see the Green LED change when jumper J1-pin 5 connects to J2-pin 2.
FTM0 PWM duty cycle is going from 100-0 and can be seen on J2-pin 10 (optionally connect it to R68 of RED LED) on o-scope.
The GPIO is used to toggle Green LED every 15 seconds.
Regards,
David
