Set up a counter, break on a memory location, do something so you can catch the processor a few cycles prior to the failure, then step through until you catch it. This is very painful, but entirely possible. Could an interrupt interfere and change the flags after the test, but be

Ok, now I'm looking at warning messages.. I get a few, all complaining about .db segs with odd lengths. So, I go look at the indicated line.. How can COMMENTS and assembler directives generate this warning? The warnings all point to the lines below, inbetween the star bars. ALL o

Digikey ED3128-ND will do the job. Or just buy a 28 pins dip 600mils, serrate in the middle (wire clipper will do it), make it 300mils wide. David VanHorn wrote: > At 04:15 PM 1/1/2004 -0800, Mark Weston wrote: > >> Brian: >> >> A 28 pin chip is much wider than a fourteen pin chi

You don't need the schmitt trigger: all AVR input pins are schmitt triggers! 200krpm = 3.3k/s You could use the ICP function on timer1 with 16us (8 mhz clock/128) resolution and measure from 18 ticks/pulse (~200k) to 65000 ticks/pulse (~60 rpm). Is that enough range? Heck, make i

William, Perhaps you may want to run your phototransistor output through a schmitt trigger such as an 74ls14 chip which will make the pulses cleanly toggle between digital one and zero. Otherwise there could be a slow rise and fall shape to the output which could confuse your cou
