[Amforth-devel] Forth word ISRs

[Robert L. <xu...@xu...>]

Hello-

I apologize if this question has been asked before on the mailing list, and
I missed it.  I spent some time perusing the archives and didn't see quite
this question asked.

I'm just beginning to use amforth for some of my ATmega-based projects, and
I have a need for a timer ISR.  Ideally I'd like this to be in Forth rather
than AVR assembly, mostly because I'm not very good at assembly.  Basically
all I want to do is keep track of the number of milliseconds since "boot",
for interval tracking purposes.  The technical documentation for amforth
makes it sound like this is possible in a native Forth word, but doesn't go
into detail, or if it does, I missed it.

Is this possible?  Am I barking up the wrong tree?

Thanks.
