Re: [avr-gcc-list] Interrupt redirect?

[v . sluiter]

Hi all,

First of all, thanks for your fast response! Secondly.. I should have
described  the problem more precisely (I had been working on this far too long
yesterday :-)...

The message to be received from the modules consists of a status and a data
message, the status messages are received at a fixed interval, and are
received simultaneously. This could be done with one interrupt routine.... The
problem comes with the data message, which is not always received. Sometimes 
both
units send data at the same time, sometimes only one module sends.... On my
way home I realised that redirecting interrupts still requires two interrupts
to be generated... *duh* :-) 
The transmitting can be done at the same time, and I only use one interrupt
to do this....

Okay, thanks for all the help so far, next time I'll try to clear my head
before mailing the list |-)

Greetings, Victor
