[General] c code for receiving 8 bit data from hyperterminal to 89c51

[Sagar Shinde]

i am doing home automation project but i dont know how to enable particular pin i.e P1.0 enable when 8 bit data is received
Description:
consider, when i send 10011101 from hyperterminal then only P1.0 pin is enabled
when i send 10111100 from hyperterminal then only P1.1 pin is enabled


please send me c code

which compiler you are using following explaination for 8051 and keil compiler.

first you have to define bit as

sbit pin1=P1^0;
sbit pin2=P1^1;

above main function.

then compare the recieved character with you data as you given

if(receiv_data == 0x9D)
	pin1 = 1;
else if (receiv_data == 0xBC)
	pin2 = 1;

thank you!!! i will try

#include<reg51.h>
sbit pin1=P1^0;
sbit pin2=P1^1;

void main(void)
{
unsigned char i;
unsigned char bit1[]="10101010";
unsigned char bit2[]="11110000";
unsigned char buff[8];
TMOD=0x20;
TH1=0xFD;
SCON=0x50;
TR1=1;
while(1)
{
while(RI==0)
{
for(i=0;i<8;i++)
{
buff=SBUF;
}

if(buff==bit1)
{
pin1=1;
}
else
{
pin2=1;
}
}
}
}




here is my code please suggest me what can i do to comparision between bit1 and receiving data from hyperterminat
