I´m checking what's new on Creator 3.3, the New Project Wizard is good, Resource-Meter is really nice (to me), but what i can't quite understand is the Macro Callbacks usage.
I got an interrupt component attached to an Digital Input Pin (assigned to the SW1 of the 5LP Proto Kit). With Creator 3.2 i just write this on the main.c file:
isr_Start();
and then write my custom code on the merge region on the isr.c file (i can do this on Creator 3.3 aswell) but i was looking to know how to take advantage of this "feature". Now to have the same results using Macro Callbacks i need to make this on the cyapicallbacks.h:
#define isr_INTERRUPT_INTERRUPT_CALLBACK
void isr_Interrupt_InterruptCallback(void); /* Function declaration as Creator Help says*/
and then need to include cyapicallbacks.h on the main.c file, plus the implementation code of the function:
void isr_Interrupt_InterruptCallback(void){
SW_ClearInterrupt();
LED_Write(~LED_Read());
}
I'm using this right? What other advantages can we have with this feature?
Thanks in advance
Carlos

There is a brief description in the system reference guide, also in component author guide,
Creator, help menu to access both.

Thanks for the info.
I can see how the location of the callback would be fixed in component API code that *I* create, however, if I add a callback to a Cypress component, for instance, will subsequent builds leave it alone, or do I need to hide it in a "Merge Region?"

Did a easy program and the code on the callback function is kept after newer builds, "merge region" is there just for backward compatibility.

I looked at it. IMHO it won't help much until cypress starts adding the hooks to the component library. But will their idea of where to add match my/our desires.
It will make it a little easier to take a library component, copy it, mod it for MY wanted hooks, then use it. It will make it easier to port to new releases.
It is more of a standard coding practice than a 'feature' like the parsing engine of regions.
All my opinion,
Ed

different files for different task This is usually solved using a .h file (only Declarations, no variables except externals) and the corresponding .c file. The .h file is #included into main.c (and of course in the corresponding .c)
