LPTMR to Trigger ISR every second

Hello all,


I am trying to write an application that uses the LPTMR module of the FRDM-KL26Z to toggle an LED every second.

However, the LED is just lighting steadily. I am not sure if the ISR that I have created has been triggered or is correct. Below is the code for my LPTMR module.



The "DELAY_MS" has a value of 1000 in my header file.

RESET = 0 in my header file.


I got an idea that the ISR that I have created needs to be added in the startup file written in assembly.

Can anyone help me?


Thank you in advanced.


Best Regards,
