Hi sriram marisetty ,

Please refer to the FRDM-K22 sdk code, the official FTM code already connect the FTM PWM pin to the RGB LED.

You can download the code from this link:

https://mcuxpresso.nxp.com/en/select

Then refer to this code:

SDK_2.5.0_FRDM-K22F\boards\frdmk22f\driver_examples\ftm\simple_pwm\iar

The PWM pin is PTA1, it is FTM0_CH6, it connect to RED_LED.

Wish it helps you!

If you still have question about it, please kindly let me know.

Have a great day,
Kerry
