Can I use two FTM Dual Edge Capture block?

[utkuckmgl]

Hello,

   I need to get two different time values which are Rising-Falling edge time and Rising-Rising time of one PWM signal. I'm changing duty cycle with potentiometer and assuming observe same duty cycle value from (Rising-Falling time)/(Rising-Rising time) calculation.

   Used different modules and different pins(I made connection of pins on breadboard with jumpers) caused error. I can take time values seperately but when I use two blocks at same time I have error. Can you please help me with this, thank you.

Hello utkuckmgl@gmail.com‌,

I can't reproduce it on my side.

Can you please tell me which MBDT for S32K are you using (run the ver command in Matlab and tell te results for MBDT). Also please consider attaching the model and the generated code :smileygrin:.

Thank you,

Marius
