PIC18F26K22 UNDER FLOW ERROR

Posted: Tue Jan 18, 2022 6:18 am

Hi guys! This is too much for me, I need help.

I am developing a new code for my clock, using the 18F26k22 and an 8 bits LCD routine. Everything was just fine, until I added the external RB0 ISR, that’s receives an 1Hz clock pulse from RTC. At this point, the program starts to show strange behaviors, and I start the MPLAB SIM to check what is going wrong.

All code works fine, but when I set PC to the EXTERNAL ISR, the debugger shows the following error:

CORE-E0002: Stack under flow error occurred from instruction at 0x0000ac

Really don’t have any idea of what is going wrong!

This is my list!

Code:

Don't have any idea how to solve this, and never get this error before. May be something is wrong in the EXT ISR configuration, I don't know, please help me!

you enable an interrupt for the CCP but I don't see the 'handler', the 'INT_CCP{}..... code If you don't have the ISR code, eventually the PIC program will crash. you say you use an RTC, which one ? also why update sec,min,hrs in the ISR why not just read the RTC.Also most(all ?) require a 'setup' or 'initialization' .

Hum..... The CCP interrupt is commented, it is not enable. I just GET the time at the beginning, them I update the clock by 1Hz output. Please don't pay attention to this now ok? Just want to know this strange behavior. Regards;

What if the problem reoccurs when the product is in production and
is in the hands of customers ? What if it's an intermittent problem ?

A proper engineer would not want this or allow it. A proper engineer
would want to find out why the problem occurred, and fix it.

You are right! But this is only for me, my use, not to sell to anybody! The problem were in the include file, the device I choose was 18F46K22, and not the 18F26K22. When I changed to correct device, the problem vanishes. My mistake as usual..... Sorry, and thank all of you! Regards.
