FTM using processor expert for K53

annamol — Wed, 17 Feb 2016 10:06:41 GMT

Hi,

I am trying to generate the processor expert code for FTM. The Init_FTM module was added and the following changes were made. I am using FTM0_CH4.

FTM clock was enabled
channel was initialized

When I port the code onto the target hardware, FTM_CNT increments , but FTM_C4V doesn't increment. What am I missing in the configuration to generate a PWM on the pin corresponding to FTM0_CH4.

I have attached snapshots of the PE configuration for reference.

Please do suggest the modification needed

Hello alex,

Why the register of FTM_C4V increase?

When you configure the channel to the PWM function , this register store the match value the

PWM output, when the FTM counter (FTM_CNT) match the value of Cnv , refer to the different PWM mode

, there will be different result , for the detail information , please refer to this part :

For example :

Hope it helps
Have a great day,
