hey I have a code for serial interfacing in C, and also a code for the stop watch design in C, so i want to know how to integrate both codes together in order to make a one hex file.
here is the code for serial interfacing:
#include<reg51.h>
void ini() // Initialize Timer 1 for serial communication
{
TMOD=0x20; //Timer1, mode 2, baud rate 9600 bps
TH1=0XFD;
SCON=0x50;
TR1=1;
}
void recieve() //Function to receive serial data
{
unsigned char value;
while(RI==0);
SBUF=value;
P1=SBUF;
RI=0;
}
void transmit() // Funtion to transmit serial data
{
P2=P1-32;
SBUF=P2;
while(TI==0);
TI=0;
SBUF=P1;
while(TI==0);
TI=0;
}
void main()
{
while(1)
{
ini();
recieve();
transmit();
}
And here is the code for stop watch timer in C:
#include<reg51.h>
#define msec 1
unsigned int sec1,sec2;
int sec1_1,sec1_2,sec2_1,sec2_2;
unsigned int
digi_val[10]={0x40,0xF9,0x24,0x30,0x19,0x12,0x02,0xF8,0x00,0x10};
sbit dig_ctrl_1=P1^0;
sbit dig_ctrl_2=P1^1;
sbit dig_ctrl_3=P1^2;
sbit dig_ctrl_4=P1^3;
sbit start_pin = P1^4;
sbit stop_pin = P1^5;
sbit reset_pin = P1^6;
int s,t;
void mplex_delay(unsigned int time)
{
int i,j;
for (i=0;i<=time;i++)
for(j=0;j<=50;j++);
}
void digi_out(unsigned int current_num)
{
P2=digi_val[current_num];
mplex_delay(msec);
}
void display(unsigned int dig1,unsigned int dig2)
{
sec1_2=dig1%10;
sec1_1=dig1/10;
sec2_2=dig2%10;
sec2_1=dig2/10;
TMOD=0x01;
TL0=0xFF;
TH0=0xDB;
TR0=1;
while(TF0==0)
{
dig_ctrl_1 = 1;
dig_ctrl_2 = dig_ctrl_3 = dig_ctrl_4 = 0;
digi_out(sec1_1);
dig_ctrl_2 = 1;
dig_ctrl_1 = dig_ctrl_3 = dig_ctrl_4 = 0;
digi_out(sec1_2);
dig_ctrl_3 = 1;
dig_ctrl_2 = dig_ctrl_1 = dig_ctrl_4 = 0;
digi_out(sec2_1);
dig_ctrl_4 = 1;
dig_ctrl_2 = dig_ctrl_3 = dig_ctrl_1 = 0;
digi_out(sec2_2);
}
TR0=0;
TF0=0;
}
void main()
{
while(1)
{
start:
start_pin = 1;
stop_pin = 1;
reset_pin = 1;
dig_ctrl_1 = 0;
dig_ctrl_2 = 0;
dig_ctrl_3 = 0;
dig_ctrl_4 = 0;
P2 = 0xFF;
s = t = 0;
while(start_pin == 1)
{
display(0,0);
}
stopwatch:
for (sec1=s;sec1<=99;sec1++)
{
if (stop_pin == 0 )
break;
for (sec2=t;sec2<=99; sec2++)
{
if (stop_pin == 0 )
break;
t=0;
display(sec1,sec2);
}
}
stop_pin = 1;
s = sec1;
t = sec2;
while ( start_pin != 0 && reset_pin != 0 )
{
display(sec1,sec2);
}
if (start_pin == 0)
{
goto stopwatch;
}
else
{
if (reset_pin == 0 )
{
s = t = 0;
goto start;
}
}
}
}
