How to Generate 1 millisecond interrupt using LPIT Module in S32K144

[sakthivelkuland]

Hello Supporting Team/ All

I have newly startup the TPMS project with S32K144 MCU, First walk through the SDK Example Startup code for my better Understanding of the MCU Initialization.

1) My Project requirement to generate the 1millisecond timer interrupt that I will use for my task calling with 2ms and 10ms container.

2) FTM channel configures as Input Capture mode to measure the External signal from the sensor and decode the signals for my application usage.

3) My Project have to use the GENY Generated CAN Driver with my S32K144 MCU, If anyone has used the third part CAN Driver embedded with 

My question,

As the example code explained the about 1second timer interrupt using LPIT module,

could you please explain to me how to setup the 1millisecond timer interrupt?

Because this 1-millisecond timer, I have used all over my project for execution of all the task.

Please help me if any one has done before..

Thanks in Advance,

Thanks, Robin &  Daniel,

I have not done the "Generate Process Export Code" Before After Generated Project build success.

► Available Update

Should I process with this Updates?

Other,

My Project has to use the GENY Generated CAN Driver with S32K144 MCU, If anyone has used the third part CAN Driver embedded with S32K144 Project?

Is there any other document or guidelines available for this implementation?

If you are using the lpit_periodic_interrupt example in S32SDK_S32K14x_EAR_0.8.6(C:\nxp\S32DS_ARM_v2.0\S32DS\S32SDK_S32K14x_EAR_0.8.6\examples\S32K144\driver_examples\timer\lpit_periodic_interrupt).
Then please modify the period in lpit1_ChnConfig0.

Thanks For your Information,

I have not fount the Program path as you mentioned,

My S32SDK screen,

Then browse  for the Example program, with My S32 Design Studio,

Soi Could not find the right file lpit1.c

any simple way there to configure the LPIT for 1millisecond interrupt timer configuration.

Note: When I have tried to build LPIT_Example project, build fail with errors.

Thanks,
