CCS/MSP-EXP432P401R: Interrupt not being created

Shelby Critcher

Part Number: MSP-EXP432P401R

Tool/software: Code Composer Studio

I have made edits to startup_msp432_ccs.c file and changed the defaultisr name to a custom name, but when I do this the interrupt function is not being created. I can look in assembly code and see that it sees that part of the program but in the disassembly views and the memory browser it is not there. I have tried manually linking the startup file to the project but I then get an error that Interruptvector has been declared multiple times. Do you know where I could remove all the instances the startup file is linked, or another way to fix this problem?

Hello Shelby,

You can use the default ISR handler provided in the startup_msp432p401r_ccs.c file in your application.

For example if you have enabled ADC interrupt, then your application should use the ISR handler "ADC14_IRQHandler". If you want to use a custom handler, then you must add this custom handler to the correct location in the array "interruptVectors".

Thanks,

Sai

I know this and I tried this but when I do this and declare the function it is never created, I cannot see it in my disassembler or memory.

Hi Shelby,

Can you share the snippet of code for how you tried adding the custom handler?

Thanks,

Alexis
