Dear all

I am trying to build delay of 1 ms using GPT start timer and I am using LPIT0ch0, I have enable even LPITIrqn via NVICISER0.

I have called enableiRq and passed lpit as arguments.please go through my code once.

Can anyone help me?

Hi @Ashish4525,

I see you have posted a similar thread on the community; I will try to answer them both on this post.

You are using EB Tresos along with SW32K1_RTD, is this correct? If so, please take a look into the EB examples for the S32K118;

Ftm_Gpt_Example_S32K118
Gpt_example_S32K118
Lpit_Gpt_Example_S32K118

The Lpit_Gpt_Example_S32K118 application uses the IP layer functionality to trigger a timer interrupt. Notification function increase a count variable by 1 and toggle state pin LED on board.

Please try this example for the GPT Pit interruption.

Best regards,
Julián

Hi @Ashish4525,

You can place a breakpoint inside your interrupt handler to confirm it is indeed running. For example, if you flash the lpit_periodic_interrupt_s32k118 example, you can place the breakpoint inside LPIT_ISR and confirm the isr is active:
