S32k LPIT Timer

Hi, 

For non autosar application, how to configure and generate the internal Timer interrupt for 1ms from the Configuration tool.

RTD Version 1.0.1 HotFix 01 AND SDK version 3.4

Hi

I did not find a place to configure the LPIT timeout in the S32 Configuration Tool interface. 

In the Clocks tool interface of the S32 Configuration Tool, you will see that the currently selected peripheral functional clock source for LPIT is 48MHz FIRCDIV2_CLK.

Therefore, it is recommended to modify the main.c of Lpit_Gpt_Example_S32K144:
/* LPIT time-out period - equivalent to 1ms */
#defineLPIT_PERIOD 48000
