The data serialization using 8051 C.

There are 2 ways to transfer a byte serially.

1)      Using serial port.

2)      To transfer data 1 bit at a time and control the sequence of data and spaces in between them.

The data serialization is very easy in C. seriously.

#include<reg51.h> /*  * send some data through port  * say P2.1  * lsb should go first  *  */ sbit p21 = P2^1; sbit lsbA = ACC^0; void main() {                 unsigned char sendMePleasebyte = 0x55h;                 unsigned char i;                 ACC = sendMePleasebyte;                 for(i = 0;i<8;i++)                 {                                 p21 = lsbA;                                 ACC = ACC<<1;                 }//end of for loop }// end of main

#include<reg51.h> /*  * recieve some data through port  * say P2.1  * lsb should come first  *  */ sbit p21 = P2^1; sbit lsbA = ACC^7; void main() {                 unsigned char i;                 ACC = sendMePleasebyte;                 for(i = 0;i<8;i++)                 {                                 lsbA = p21;                                 ACC = ACC>>1;                 }//end of for loop }// end of main
