PE overrides the interrupt vector table

[Ivand]

I am using Processor Expert to init and generate Bean code, but i also have my own interrupt routines.

The problem is PE overrides my interrupt vectors and replaces it with the default vector address.

How can i instruct PE not to override the vectors i have set?

Setting the file properties to readonly doesn't help when you re-open CW.

Any help on this would be appreciated, thanks

Hello

If you are using ProcessorExpert to generate low level drivers and if you want to associate your own interrupt function for a specific interrupt you should proceed as follows:

   - Add an Interruptvector Bean to your project

   - Initialize the InterruptVector Bean with the appropriate InterruptVector name

   - Specify the name of your interrupt function in the "ISR name" edit box.

Also if you are using your own interrupt function I assume you are programming one of the devices on the CPU yourself.

I would than also recommend you to marked the corresponding resources as used by an external device.

This can be done as follows:

  - Open the Bean Inspector for the CPU bean

  - Go to the Used Tab

  - Look for the resource you are programming outside of ProcessorExpert (for instance I/O Port A)

    and toggle its status from "ready for use in PE" to "Used by an external device".

I hope this helps.
