LVI project | Cypress Semiconductor
Hi everyone and again I hope some of you can help me with that:
I am trying to save some variables when Vdda and /or Vddd drop down 2.95 V.
I have tried to adapt the example "D" on AN 54460 for Low voltage interrupt.
I have created a small project to test the LVI feature.
To verify that the ISR is working I have set the variable "Led_On" inside the ISR.
Later in the main loop, when Vddd or Vdda drop below the threshold, I should see the led connected to the Pin 1(2) turn on a some fraction of second .
That not happen, I do not know what is missing.
Thank you very much for any help.
