Serious Warning

[Ron]

Hello,

How do I determine where this warning is coming from. I searched the "C" file using VS2008 and only found 4 lines in the code that call out FCM_TMR0. How do I locate which is causing this and where it is located in my project?

Building CASM file
Serious Warning: Possible sw stack corruption, function 'FCM_TMR0' called by more than one asynchronous thread (main/Task, interrupt, interrupt low)

The 4 areas I have found the FCM_TMR0 are listed below.

First Area Of C file
//Macro function declarations
void FCM_TMR0(); // This is required.

Second Area Of C file
//Call Macro: TMR0
FCM_TMR0(); // I think this is where I enable TMR0 in flowchart


Third Area Of C file
void FCM_TMR0()
{

//Comment: // This is the TMR0 code itself


Fourth Area Of C file
void interrupt(void)
{
if (intcon & (1 << TMR0IF))
{
FCM_TMR0();
clear_bit(intcon, TMR0IF);
}


}



Thank you,

Ron

Hello Ron,

Its hard to see without having your program but are you calling the TMR0 macro via a software macro icon or is it simply the interrupt icon that referrs to it.

If you are using a software macro call then this should not be needed as the timer macro will run by itself once you have called the interrrupt enable function.
