send data to the serial port using proteus based ATmega16

[aminanto]

I recently made ??a small project for my final project,
This project involves the transmission of data via the serial port.
I am using proteus to simulate the system as a whole and based on ATmega16.
since my laptop does not have a serial port so I
using Virtual Serial Port Emulator. While I use huperterminal to receive data transmitted by the microcontroller. I just do not have the data sent by the microcontroller.
Someone please help me, I’ve thought about it for hours and did not manage to make the data sent ..

This is a screenshot of proteus and code. ..

 

#include <mega16.h>
#include <stdlib.h>
#include <delay.h>
#include <io.h>

#define ADC_VREF_TYPE 0×40
#define USART_BAUDRATE 9600
#define BAUD_PRESCALE ((8000000/ (USART_BAUDRATE*16UL)) – 1)
//————————————————

unsigned int ADC_read(unsigned char adc_input);
void ADC_init(void);
void usart_init();
void usart_putch(unsigned char send);
void USART_transmit(unsigned char data);
void SEND_reading(unsigned char abc);

void ADC_init(void)         // Initialization of ADC
{
    ADMUX=(1<<REFS0);
    ADCSRA=(1<<ADEN)|(1<<ADPS2)|(1<<ADPS1)|(1<<ADPS0);    // faktor pembagi 128
}

void usart_init()
{
    UCSRB |= (1 << RXEN) | (1 << TXEN);   // Turn on the transmission and reception circuitry
    UCSRC |= (1 << URSEL) | (1<<USBS) | (1 << UCSZ0) | (1 << UCSZ1);
    // Use 8-bit character sizes
 
    UBRRL = BAUD_PRESCALE;
    // Load lower 8-bits of the baud rate value into the low byte of the UBRR register
    UBRRH = (BAUD_PRESCALE >> ; // Load upper 8-bits of the baud rate value..
    // into the high byte of the UBRR register
}

void usart_putch(unsigned char send)
{
    while ((UCSRA & (1 << UDRE)) == 0); // Do nothing until UDR is ready..
    // for more data to be written to it
    UDR = send; // Send the byte
}

void USART_transmit(unsigned char data)
{
  /*
  while((UCSRA & 0×20)==1)
  {
  UDR=data;
  }
  */
  while ((UCSRA & (1 << UDRE)) == 0); // Do nothing until UDR is ready..
        // for more data to be written to it
        UDR = data; // Send the byte
       
}
   
void SEND_reading(unsigned char abc)
{
    unsigned char k,l,m;
    k=abc/100 + 48;
    l=(abc/10)%10 + 48; 
    m=abc%10 + 48;
    USART_transmit(k);
    USART_transmit(l);
    USART_transmit(m);
    USART_transmit(‘,’);
}

// Read the AD conversion result
unsigned int ADC_read(unsigned char adc_input)
{
    ADMUX=adc_input | (ADC_VREF_TYPE & 0xff);
    // Delay needed for the stabilization of the ADC input voltage
    delay_us(10);
    // Start the AD conversion
    ADCSRA|=0b01000000;
    // Wait for the AD conversion to complete
    while ((ADCSRA & 0×10)==1);
    ADCSRA|=0b00000;
    return ADCW;
}

void main(void)
{
    unsigned int value;
    DDRA=0xFE;
    DDRB=0xFF;
    DDRD=0xFE; //0×03;
    ADC_init();         // Initialization of ADC
    usart_init();

    while(1)
    {
        value=ADC_read(0);
        value=value*500/1024;
        PORTB=value;
        usart_putch(‘C’);
        //SEND_reading(value);
        delay_ms(100);
    }     
}

 

 

 

 

 

 

 

 

 

 

 

one more, I’m using code vision

I would greatly appreciate any help you guys

It is your final project right? If you’ve done your code, then why don’t you try it on real hardware and find the result ! The simulation software can’t completely simulate the rael hardware at it fails most of the time to get the correct result due to countless reasons.

Hi i m working on the same project with help of proteus but i m getting the problem, i m not getting ht12e in proteus i hav tried to download a lot but i m not getting so can you plz provide me the. dsn file along with libraries

[AJISH ALFRED]

Hi all,

Please don’t waste yourm time on simulating things, try it on real hardware!

[Ashutosh Bhatt]

may be problem in your  BAUD_PRESCALE

for 8 MHZ your UBRRL must be 33h. try this direct value.

[manimaran]

The problem is you are not having the idea about the proteus. Proteus can send the data to outside world by using compim. And also try to change the baud rate in virtual terminal. Then check the crystal value in microcontroller properties..

[sashi]

yes ,u shoud check the clolk freq of micro controller on proteous ….and the check the boud rate of virtual terminnal ……
