http://www.dunfield.com/downloads.htm it does not look like there is a C
compiler found here at all

how to program that 2051 so that I have the same of result

when I apply the realterm.

and suppose to store "hello world" in a register or P.X , I need help

1. idenify itself "I am here" like hello world in

#include c:\mc51io.h  /* include i/o header file */
#include c:\mc51reg.h

printf, sprintf, concat
int main()
{
unsigned char temp;
BAUD = 0x30; // 9600b
SCCR1 = 0x00; // 8-bit mode
SCCR2 = 0x0C; // enable Tx/Rx, no interrupts

printf("Hello, world!\n");

temp = 0;
while(1)
{
if(temp%2)
PORTA = PORTA | 0x10; // turn on Port A, pin 4
else
PORTA = PORTA & ~(0x10); // turn off Port A, pin 4
temp++;
}
return 0;
}


no sure if this will work  since I have not compile micro-c compiler


TIA
