Hello ,
I am using LPC54628(OM13098) development board.
I intent to use PWM output with different period.
Is it possible to have different PWM period in SCT0?
e.g.
SCT0_OUT4 with 50KHz period (+ variable Duty %)
SCT0_OUT6 with 100KHz period (+ variable Duty %)
regards,
Hemanth
Hello Alice,
Thanks for your inputs.
Is possible to configure the SCTimer as complimentary pair?
e.g.
SCT0_OUT4 with 100KHz period (+ variable Duty %)
SCT0_OUT6 complimentary output of (SCT0_OUT4)

Hemanth
Hello Hemanth,
Yes, just config output3 and output4 with opposite level.
Recommend you use the MCUXpresso Config to config it:
There are PWM demo under SDK:

Hello Alice,
Thanks for the info.
How to set the dead time in SCTimer/PWM?
Is it possible to have complimentary PWM pair in CTimer?
I couldn't get any options.

Hello Hemanth,
You can have a look at the SCTimer cookbook, it includes these demos you mentioned.

Hello Alice,
Thanks for the info.
Is complementary PWM with dead time possible from C Timer? The above reference tells mostly about SC Timer.

Hi Hemanth,
No, because "All single edge controlled PWM outputs go LOW at the beginning of each PWM cycle.
Each PWM output will go HIGH when its match value is reached."

Thanks for the info Alice.
