[SOLVED] conversion of hexadecimal to decimal code in 8051 embedded c

[vattipalli]

hi,
my work is to read data from temperature sensor which is interfaced to 8051, i can read it but to display it , i need to convert hexadecimal to decimal, plz any one give some info how i can convert it and display it.

Dear friend,

If you are using mikroc ,then

Bcd2Dec16(unsigned bcdnum);

I have posted a thread about converting hex value to BCD(decimal value). Just check that thread. The code is included in it....

// to initialize adc.

void Timer_Init()
{

}

void UART_Init()
{

}

void Send_Char0( unsigned char Data)
{

SBUF0 = Data;

SCON0 &= 0xFD;
}

void ADC_INIT(void)

}
void sys_init(void)
{
Timer_Init();
UART_Init(); //sys intialization.
OSC_INIT();
PORT_INIT();
ADC_INIT();
}



void main(void)
{
unsigned int d1 = 0, d2 = 0, d3 = 0, d4 = 0,read_h = 0x00;
unsigned int x = 0,y = 0;
unsigned char Data = 0x00;

PCA0MD &= ~0x40;
sys_init();


AD0BUSY = 1;
while(1)
{
if(AD0BUSY == 1)
//TO START ADC CONVERSION.

read_h = ADC0H; // adc data in hexadecimal
x = read_h;
// decimal conversion
d1 = x / 100;
x = x % 100;
d2 = x / 10;
x = x % 10;
d3 = x;


P0 = d1;
P1 = d2;

Data = (unsigned char)(P0);
Send_Char0(Data);

}
}
plz check my code once. i am getting junk(symbols).

Which compiler have you used? I have done my code in MikroC.......

[vattipalli]

c8051f920 silicon labs microcontroller. keil compiler

 

[incomplete_jerin]

Haven't used that.......
You want the conversion of adc hex value to decimal rite?
Store the 10 bit value to a variable of integer type & do the divide operation as explained in the code.
