Hi

I have the code and schematic for zero crossing detector, and code for 1/2 cycle AC /10 whether it goes to positive from 0 or negative half cycle from 0.

Since every 1/2 of AC is devided with 10 divisions for equal time,(for 50Hz, 1 full AC cycle=200ms so line crosses at 0 volts at every 100ms, and if we devide 100ms into 10 = 10ms at every increment) the power output for every increment in number of divisions are not equal.

I could not get the time to measure the output power after every increment or decrement. But the concept is working so far so good, now it is the just the matter of fine tuning the code.

I am sure many of gurus have already done this, one way or other, but still if someone wants to see my code, he/she is welcome. Please Email me.

babar, I already sent you this code some time back. If you still require this, please let me know.
