External Interrupt on both Falling edge & rising edge

ABORT!, ABORT!, ABORT!
01/01/70 00:00
Better circuits exists
01/01/70 00:00
one more
01/01/70 00:00
DANGER!! Don't Try This At Home!
01/01/70 00:00
Its not just Atmel
01/01/70 00:00
interrupts on both edges
01/01/70 00:00
Thank you All

Read about external Gate for Timer
01/01/70 00:00
gate for timer
01/01/70 00:00
Jan, will you Shhhhh!!!
01/01/70 00:00
Great Idea !
01/01/70 00:00
But i've used up INT0 and INT1 pins
01/01/70 00:00
int0 is gate for timer0
01/01/70 00:00
T1(T0) pin is not use here
01/01/70 00:00
so only one Ext.int pin will do
01/01/70 00:00
i think so
01/01/70 00:00
I haven't tried it yet
01/01/70 00:00
is a Zener that costly?
01/01/70 00:00
so try something safely
01/01/70 00:00
That the most exhaustive reply i got so far !
01/01/70 00:00
You are wellcome
01/01/70 00:00
Here's what i have done
01/01/70 00:00
simulation is partial
01/01/70 00:00
I'll try writing a sample code
01/01/70 00:00
Dimmer
01/01/70 00:00
its a dimmer for commercial sale
01/01/70 00:00
Dimmer
01/01/70 00:00
Its in my Profile
01/01/70 00:00
is 8051/2 I/O similar to Zilog Z8
01/01/70 00:00
Cease and Desist
01/01/70 00:00
It's DANGEROUS - It's not about the IOs!!
01/01/70 00:00
Either you are NOT listening...or you don't want to listen
01/01/70 00:00
It's worse than that!
01/01/70 00:00
Its like openning Pandora's box
01/01/70 00:00
chip A != chip B != chip C
01/01/70 00:00
Consider these points...
01/01/70 00:00
not a newbie to electronics
01/01/70 00:00
What results do you really get from an experiment?
01/01/70 00:00
Reply to Arun Kumar V
01/01/70 00:00
what if the result is death?
01/01/70 00:00
very positive opinion
01/01/70 00:00
Thanks for the pointer
01/01/70 00:00
A generic approach to dual edge detection
01/01/70 00:00
Here is the method I have been using...
01/01/70 00:00
Oh Noes!!!!!!
01/01/70 00:00
4 -> 10 nsec Pulse Does Not Work for MCU
01/01/70 00:00
No additional logic gates
01/01/70 00:00
Modifying design
01/01/70 00:00
Yeah But...
01/01/70 00:00
If you say so
01/01/70 00:00
Poppycock
01/01/70 00:00
Why you should not do this...
01/01/70 00:00
Galvanic isolation
01/01/70 00:00
Can't we use single AC optocoupler
01/01/70 00:00
not 1,8V
01/01/70 00:00
can be wrong circuit below
01/01/70 00:00
Critical again...
01/01/70 00:00
varistor?
01/01/70 00:00
Yes, but...
01/01/70 00:00
You can do a lot of things...
01/01/70 00:00
25V is too coarse
01/01/70 00:00
use tha appnote I gave you the link to
01/01/70 00:00
25V is not bad
01/01/70 00:00

No headphones
01/01/70 00:00
Then take a better opto!
01/01/70 00:00
he wants to build a Yogo, not a Mercedes
01/01/70 00:00
which makes the lamp flicker when the fridge turns-off
01/01/70 00:00
it (probably) does that anyhow
01/01/70 00:00
No body wants to buy a Mercedez
01/01/70 00:00
