hello,
i'm still new to proteus and currently working on impact sensing circuit.However,i'm facing some errors once i try to simulate the circuit, as the errors,'no models specified' is being displayed upon the simulation. Thus, i really need some suggestions and guidelines from you guys.Thank you very much.Below are the image of my circuit:
 

As you have said before, i have clicked all the connectors and checked the 'Exclude from Simulation' options, and the circuit shows no error upon simulation. However the lcd screen doesn't display anything,even though i have inserted the specific coding,as shown below:

}


your reply would be most welcomed.

Try this code. Also Connect Vss of LCD to GND and Vdd and Vee pins to +5V and pot respectively. If you are testing in hardware then according to your LCD connections the LCD will be dead. Also you have to pull up MCLR pin. You have connected to GND. It will keep the processor in RESET state.

Is this the connection that u mean ?

I also have few questions:

1. Where should i pull up the MCLR pin to ?
2.what do u mean by,'testing in hardware then according to your LCD connections the LCD will be dead'....is that mean that the output is achievable only if using proteus and not by using hardware (in real life) ?
 

The LCD connections shown in post #6 is right. Connect MCLR pin to +5V through a 10k resistor. I meant if you are testing in hardware and not only in Proteus, then if you had connected LCD as in post #1 then LCD will be already dead due to applying reverse voltage.
 

OH..thanks for the help

one more help..i've another string of codings,as shown below:

void main()
 
while(true)
 
  if(input(PIN_DO))
  {
  output_bit(PIN_D1,0);
  printf("No Detect\n\r");
  delay_ms(500);
  }
   else
  {
  output_bit(PIN_D1,1);
  printf("\fDETECT1\n\r");
  delay_ms(500);
  }
}//close while
}//close main


The problem is,once i tried to paste the above coding with the previous one,it displays error in simulation.I used microC PRO for PIC for your attention.

oh, the codings are from different softwares,is it ? Then how i need to change the above coding,so that it will compile with lcd coding ? and yes microC gives the error when i compile the above coding with lcd coding.

while(1){
 
    if(PORTD.F0){
        Delay_ms(50);
        if(PORTD.F0){
            PORTD.F1 = 0;
            LCD_Out(2,1,"No Detect");
        }
    }
    else if(!PORTD.F0){
        Delay_ms(50);
        if(!PORTD.F0){
            PORTD.F1 = 1;
            LCD_Out(2,1,"Detect   ");
        }
    }
 
}
 

Thank for the code,however the microC displays error upon compiling the above coding with previous code (lcd)

thank you very much for the coding. Do you know how to write coding in order to display gps location(longitude & latitude) to specified number in form of sms using gsm modem ?
