| External Interrupt on both Falling edge & rising edge | | 01/01/70 00:00 |
| 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 |

| Thank you All | | 01/01/70 00:00 |
| 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 |

| 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 |

| 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 |

| 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 |

| 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 |
| You still don't know what my product is? | | 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 |
