[En-Nut-Discussion] using Timer1 16bit interrupt

[Damian Slee]

Hi,
I'm trying to make use of the Timer1 interrupt.  I don't think is being used by NutOS.

I am working with the HTTPD sample, which is working.

When I add a call to NutRegisterInterrupt(), I get linker errors for multiple define interrupt vectors.  It appears that the libnutdev.a includes ivect*.c, but also irqreg.c, where NutRegisterInterrupt() exists.   Both have SIGNAL() handlers.

Is there anyway of making it use one or the other? without rebuilding the library without ivect*.c?

--------------
#include <dev\irqreg.h>
...
{
	NutRegisterInterrupt(IRQ_TIMER1_OVF, MyTimer1_Interrupt, NULL);
}
--------------------

makefile
...
LIBS =  $(LIBDIR)/nutinit.o -lnutpro -lnutfs -lnutos -lnutdev -lnutnet -lnutcrt
...
