View Full Version : Output a 1mhz 'clock' signal via BS2
08-23-2008, 08:00 AM
I messed up a few of my Atmel AVR chip fuse settings and it was recommended that I can fix if I can feed it a 1mhz clock signal.
Is it possible to use my BS2 to output a 1mhz pulse?

Why don't you just use a 1 MHz oscillator?

WHy buy a hammer if a brick works?

Because a hammer works better at removing nails.

And there's not as much surface area with a hammer in case you miss... http://forums.parallax.com/images/smilies/smilewinkgrin.gif

a 74HC14 with a 1MHz crystal may be·a simpler solution...· If it doesn't need to be 'exactly' 1MHz you could fudge with a 555 or even a 74HC14 for that matter.

Well, if the OP is anything like me, he has no patience (or spelling skills, but its 5am, lol) and wants to fix this with whatever he can find at home. Sounds to me like he just needs to feed the chip the signal long enough to get it fixed\reprogrammed, and not again.
That being said, I dont know, but I didnt think the stamp could do that fast, if you have a 555 timer, which any electronics scrap box should, it can be done.
