k64 pwm output pin

hotashu — Tue, 18 Aug 2015 08:54:11 GMT

hello expert,

in the past i used K64 on KDS+processor expert. i can set PTC2 as output PWM wave.

now i use K64 on KDS+KSDK processor expert, using fsl_ftm component, (because no PWM component supportd in KSDK processor expert. ) . but i found PTC2 is not avaiable for PWM output in fsl_ftm.

please instruct me how to use KDS3.0+KSDK processor expert to output pwm on PTC2.

thanks.

Hello Hotas,

Please try with the FTM0_CH1 instead of the FTM0_CH0, is the PTC2 pin available?

Best regards,

Earl.

hi,

I think Earl is correct.

In addition, I made a demo code use FRDM-K64 + KSDK processor expert. see attached.

PWM output PTC2, FTM0_CH1, frequency is 10Khz. duty cycle is 50%.

this is the wave output from PC2 pin from scope:

Have a great day,
Zhang Jun
