Pulse generator using p89c51rd2

sonarO connected to INT0 pin P3.2 not P1.0 to make things easier.


sonarO = 0; //make it o/p pin and o/p low on P3.2
sonarO = 1; //
5uS delay// or whatever u want to keep
sonarO = 0;// pulse complete L-H-L
//no delay required, prepare your controller for calculating time..
sonarO = 1;//make it i/p pin to read the pulse width
TMOD = 0x09; //Timer0, 16bit gate controlled(P3... Read Compelte post
