Hi Adam,
I'm trying to use an 8051 to generate a PWM and it doesn't seem to be working. Attached below is the code I used, could you help check it and point out where I made a mistake?
This is for my project and I'm presently frustrated. Kindly help.
Note: the values I have used are just for simulation purposes and are not mearnt to be used on the servo.


#include<reg932.h>
sbit pulse=P0^0;
unsigned long count_high=50000;
unsigned long count_low=50000;
void main(void)
{
TMOD &= 0xF0;
TMOD=0x02;

EA=1;
pulse=1;
TH0=0xB8;
TL0=0xB8;
ET0=1;
TR0=1;
while(1);
}


void x(void) interrupt 1
{
if (pulse==1)
{
if (count_high==0)
{
pulse=0;
count_high=50000;
}
else
{
count_high--;
}

}
if (pulse==0)
{
if (count_low==0)
{
pulse=1;
count_low= 50000;
}
else
{

count_low--;
}

}

}
