Hi Bruno,
My apology for the delay in my
response.
This feature
is not supported in Processor Expert.
Allocation of the interrupt, without using a bean for the
peripheral, is
supported by a special bean InterruptVector which allows
you to specify name of
the ISR and generates a name of the IRS into vectors.c
file.
However, the runtime changes of the vector is not directly
supported in this
case as well and you will have to do this within your code
(for example using
an IF condition or using a function pointer variable).
Hope this helps.

Again
with that question. With the SDK, I was using the function
:
but now with CW7.0, I'm stock
without that SDK function.
My question is: how can I set dynamically an ISR in
the interrupt
vector?
Thanks,
Bruno

Hi
Bruno
I'm on CW 6, not 7. Also, we do not use PE except in
little "stub" projects, to produce sample code snippets..
What we
use for the vector table has a name like "vector_isr.ASM", or
"vectors.c" . I forget where we got the first version of vector.ASM - maybe
from stationary, or some sample program. The sample vector.c file came
from Processor Expert.
To
select the ISRs at compile-time, we basically type in the name of the C function
that has "#Pragma interrupt saveall", preceded by an "F", directly into the
vector table. You have to provide a function prototype in
vector_isr.ASM.
Little
bits of sample code are below, from Metrowerks.
Is that
what you were trying to do? Or do you want to change the ISR at
run-time? For that we made the real ISR call a function pointer, and we
change the function pointer at run-time. In the example below,
"FISR_GPIO_Port_D_Interrupt " means "jump to the C function
"ISR_GPIO_Port_D_Interrupt" . That function has "#pragma interrupt
saveall". It calls a function pointer, that we set up at runtime, usually
a different function pointer for each pin on PortD.
