Hi to all,
I'm trying to generate PWM signal starting from fsl_ftm component.
developing with KDS 2.0.0 and KSDK 1.1.0 on K20 device (i'm using K60 for PEx because KSDK for k20 is not ready yet)
I want to generate a PWM with frequency 10 Hz and 50 duty cycle
setting of PEx flex timer are:
basic config: overflow= 0, write protection disable, BDM = zero mode, SW trigger enabled and disabled all HW trigger
pwm chan config: Freq= 10 Duty=50, Edge mode= high true. mode= edge alligned pwm
pin, all disabled (fault all disabled; external clock pin disabled, HW sync disabled)
init: timer overflow interrupt and fault interrupt disabled
PWM channel: #2 ---> Pin PTA5
If I use Freq > 400 Hz all work right... but if I set 100 Hz (more then my 10Hz wanted) i see a PWM of about 550 Hz....
Why this problem occours?
