SCTimer in LPC845 is not invoking with IRQ

angiey0017 — Wed, 26 Jun 2019 16:16:12 GMT

Hi,

I need to generate a PWM signal with lower frequency say from 0.5hz,1hz...and want to execute

using interrupt, so checked with the sample code of [sctimer_16bit_counter] without interrupt call

getting the 1hz pwm signal, but after adding ISR not getting the pwm signal since interrupt is not

invoked, kindly suggest any changes to be done in the implementation in the attached file.

Thank you

Hi ,

Thank you for your interest in NXP Semiconductor products and
the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you to refer to the sctimer_pwm_with_dutycyle_change demo in the SDK for details.
Have a great day,
TIC
