A bug in 8.2

I tried to create a component that uses an interrupt handler. Unfortunately the name mangling used doesn't seem to apply to the macro called in the enable interrupt icon.

A simple example:

bug.fcfx: (7.48 KiB) Downloaded 157 times

Which creates a simple component with an Init macro.

int_bug.fcpx: (1.03 KiB) Downloaded 166 times

A program that attempts to use this:

bug_demo.fcfx: (6.17 KiB) Downloaded 144 times

The C generated for the interrupt handler:

Code: Select all

void FCD_0ff51_int_bug1__interrupt_handler()
{
    //Local variable definitions
    MX_UINT8 FCL_N;

    // .n = 1
    FCL_N = 1;

}

& the interrupt setup using the wrong name is:

Code: Select all

    
    ISR(USART0_RX_vect)
    {
        FCM_interrupt_handler();
    }

Which gives compilation errors

Is there a way around this - force FC to use a particular name etc ??

Hi Martin,

Yes there is an event macro to allow you to add interrupt code inside a component. I'll send you a PM with an example.
