#175313 - simulation is partial Responding to: ???'s previous message |
If You build ZCD and measure with real oscilloscope - You will see something like simulated waveforms. But trying to predict real circuit, when ZCD is connected to real IC - this is another thing.
Every 3 options are acceptable, if firmware sees what "oscilloscope" shows. Otion with 2 resistors - one at each wire from mains - is good for safety. I'm lazy to read DC characteristics of 80x51 INT0 pin. You should read and think. In Your simulation add load , adequate to INT0 pin. I'm little sceptic, because i never used simulator. Sorry. |
