How are interrupts handled in custom PSOC 4 components? Normally I have had to comment out the interrupt handler in the isr.c file in order to use the isr_StartEx() and put the ISR code in my main.c. However, as far as I can tell, when you make a custom componant the API code for included componants isn't generated until runtime. How should this be handled?
Hello
Double-click the TopDesign.ctl file to open it for editing. The attribute keyword is used in the control file to specify the interrupt vector number for each interrupt component. The method of specifying the interrupt vector number depends on whether the interrupt component has been placed by the user on the example schematic or the interrupt component is used internally in a PSoC Creator component in the schematic. The method is as follows:
a) For the interrupt components placed by the user on the schematic, the syntax is:.
attribute placement_force of instance_name : label is "Intr(0, DesiredVectorNumber)";
Here instance_name refers to the name of the Interrupt Component in the schematic and DesiredVectorNumber is the vector number (0 to 31). For example, to assign vector 17 to the Interrupt Component isr_1:
attribute placement_force of isr_1 : label is "Intr(0, 17)";

I hope my answer can help you.
