phase angle control 89s52

hey guys. i am planning to create project using principal of phase firing angle.

my reference is this site http://www.8051projects.net/news-i188-single-phase-ac-motor-speed-controller-project-report.html. in the download page you will find the report,code,and schecmatic.

using that reference i model it into proteus(attached)
using the same code:

#include<reg52.h>


#define bargraph P2

sbit  led1 = P3^7;
sbit  led2 = P3^6;
sbit   s1  = P1^0;
sbit   s2  = P1^1;
sbit   s3  = P1^2;
sbit pulse = P0^0;

in the oscilloscope the form of wave doesn't change. what could be the cause?

when i connect the output of zcd to MCU, the probe 1 in oscilloscope read it as full dc (flat). if i dont connect it, the probe 1 read it as pulse each 10ms

anybody?

This is a cut down version of your circuit that works.
It may give a starting point to fault find the full circuit.

Remember to use SW1 to turn the power on.

How much of your PC's cpu power does it take to simulate your full circuit ?

how do i know the power that i used for running the circuit? is it the power that i used to plug to my computer?

In Proteus, click the "Run" button.
Move the mouse cursor to the area just below the Run/Stop/Pause buttons
The text will display something like "CPU load 34%"
If too high ..say 99% the simulation will be slow and not reliable.

the load using your project is 23% and using mine is 80-90%. why is that?

what happen about this, in simulation, when i connect the output of zcd to MCU, the probe 1 in oscilloscope read it as full dc (flat). if i dont connect it, the probe 1 in the optocoupler pin 5 read it as pulse each 10ms

i change the mcu in proteus using 8535, and its fine. the zero cross is detected. when i use 89s52, the zcd not pulsing each 10ms.

is it just in simulation? because there is no oscilloscope around me right now

when using clock generator instead of moc npn, the oscilloscope in proteus can show that zcd pulsing.

if i use moc npn, the oscilloscope cant show any. if it just output of moc npn (without connecting it to interrupt pin), it can shows.

@ bagusdj
do not make a full circuit in the Proteus
some things in Proteus will not work as we think
simply check a logic in Proteus is it ok or not
the pin that is controlling the fire angle
check on that is wave is present or not
wave will be like a pwm signal

i tried to simulate only the moc npn and the 8051. no signal detected (the colored box indicated hi or low doesnt blink). when i replace it with 8535 in the same schematic, it pulsing. here is the example (attached)

if you dont connect it o int0, it reads pulse. if you connect it, it flat.
