Serial Communication (Simplex)

Defination

In telecommunication and computer science, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.

Types Of Serial Communication:

1. Synchronous
2. Asynchronous (Discuss In This Post)

Modes Of Communication 

1. Simplex (Discuss in This Post)
2. Half Duplex
3. Full Duplex

7- Segment Multiplexing Technique

Turn off all 7- segment place data on data bus of 7 segment now turn on the 7 - segment for a short time approx half or 1 millisecond then turn it off now place data on data bus for other segment and repeat the process one by one for all 7-segments.

Selecting the type of port pins

Before you start playing with the port pins, you should declare their type. Each one can be Input or Output. for selecting a pin as output you should clear it's respective TRIS bit for example if you want that pin3(RB2) of PortB act as output so you should clear TRISB.2 using

Command in Basic Language:

LOW TRISB.2

Command in C Language:

TRISB2_bit = 0;                            or                   TRISB &=  ~(1 << RB2)

Similarly for selecting a pin as input you should Set it's respective TRIS bit for example if you want that pin4(RB3) of PortB act as output so you should SET TRISB.3 using

Command in Basic Language:

HIGH TRISB.3

Command in C Language:

TRISB3_bit = 1;                            or                   TRISB |=  (1 << RB3)
