yes, but these are for waiting, not measuring time.

Thanks, looks easier then i thought it would be.
Will try to do something similar.
Is there a special reason you selected timer 2?
I was thinking about using timer 0.

Hello,
my build of amforth trunk (r957) fails with amforth-eeprom.asm
that VE_ROOT is not defined anywhere.
It seems that even ONLY restores the wordlist order to contain
FORTH vocabulary and there are no words defined in VE_ROOT.
A patch below removes the VE_ROOT altogether, but I am not sure

Robert,
long time back I used these words for time measurements:
\ 2007-12-26 EW w4_clock_tick.fs
\ 2010-09-02 PITO - FLOAT TIME MEASUREMENT ATMEGA 32
\+timerregister and enable interupt
\-timerdisable interupt
\ this is for mega32
marker -mytimer
\ TIMER_COUNTER_2
$42

The directory examples may be a starting point. More can be found
in the subversion tree /applications

Does amforth set up a timer to measure time or do I have to do that by
hand? I need a word similar to arduino micros() to keep track of time.
Has somebody already written that?
btw: What hw initialization (like timers, setting up i/o pins and the
like) does amforth do, if any?
