Can any one tell me how can I compile this c program of 89c2051 :-



#include d:\mc51\8051io.h
#include d:\mc51\8051reg.h
extern register unsigned char speedleft,speedright;
register unsigned char high,low,flag,time;

main()
{
P1=0x40;
P3=0xff;
high = 80;
low = 30;
flag = 0;
time = 50;
Start();
while(1) {
P3|= 0x0f;
Run();
}
}

Start()
{
char exit,key;
exit =1;
while(exit)
{
key = P1;
if((key & 0x40)==0) exit=0;
}
}

Run()
{
char sensors;
sensors = (P3 &=0x0f);

if((sensors & 0x01)==0) {
TurnRight();
flag = 1; }

else if((sensors & 0x08)==0) {
TurnLeft();
flag = 2; }
else if(sensors == 0x09) {
Forward(high);
flag = 0; }

else if(((sensors==0x0b)||(sensors==0x0d))&&(flag==0))
Forward(low);

}

Forward(char speed)
{
P1=0x64;
speedright = speed+10;
speedleft = speed;
delay(time);
}

TurnRight()
{
P1=0x68;
speedright = low+5;
speedleft = low;
delay(time);
}

TurnLeft()
{
P1=0x54;
speedright = low+5;
speedleft = low;
delay(time);
}

Reverse(char speed)
{
P1=0x58;
speedright = speed;
speedleft = speed+5;
delay(time);
}

Detail man! Compile it to run on what? Where did you write it? In an IDE? What MCU, if any, are you going to be ultimately using it for?

OP has posted exactly once, 14 months ago. Probably isn't checking here for a solution.
