Interrupts in C6000

Manuel Fernandez-Ros

Hi, my name is Manuel

I need to work with interrupts (C6455 and C6713). I have found a lot of information about them, but I don't find a single complete example. I explain, if I want that a function is a subroutine for the interrupt (ISR), I must write interrupt my_func_int (void). Well, ¿how can I pass its adress to the interrupt vector table? For other (and simple) processors (8051) there are a set of funtions to make this.

Sorry for my little english.

Best regards.

Manuel,

The best way to configure interrupts (and assign ISRs) depends on whether or not you are using DSP/BIOS in your application. Please take a look at this older post for a list of helpful resources:

Let me know if you need more information (or example code) for one method in particular.

Dear John,

I know all documents that are in the link (and more).

First, I don't use DSP/BIOS, I'll do it later. I have created a simple (I think so) project without DSP/BIOS on a dsk6455. I'd like work like I've done with other processors (8051) if it's possible.

I think I must manage the memory for the vector table, its allocation in the memory, and then pass to it the address of the ISR. I thought that it was easier, but now I don't think so.

Could you help me? Have you got any simple example? I'm working with timer interrupts, when the timer finish the count I send a message to 'console'. It's a simple program, but with it I can see how manage the vector table and allocations in memory.

If you know some example or forum it will be wellcome.

Best regards.

Manuel,

I don't have any examples that configure interrupts using only basic register access, but there are several examples showing how to configure interrupts using CSL. First, download the CSL release for C6455 from this page:

http://focus.ti.com/docs/toolsw/folders/print/sprc234.html

Navigate to the csl_c64xplus_intc\example\c64xplus\intc folder inside the CSL installation to find the interrupt controller examples. Please let me know if this works for you, or if it's still not what you're looking for.

Joe,

I know that document, but is too abstract for me. I have always worked in low level. In any case thanks four your time.

Best regards.
