LAB REPORT
EXPERIMENT # 8:INTRODUCTION TO ASYNCHRONOUS
SERIAL COMMUNICATION USING PIC18F4520’S BUILT IN
SERIAL PORT
PROCEDURE:
In this experiment we have completed our task of communicating microcontroller with
PC using asynchronous serial transmission on hyper terminal. So, firstly we have made a
read and write function in which we have transmitted data through write function and
then received data using read function. This work is done in following steps:
1- We set the baud rate to 9600.
2- We configured serial port using TXSTA and RCSTA registers
3- Then we communicate using hyper terminal
4- Firstly we printed welcome message
5- Then we transmitted data using transmit function
6- It is then displayed on the hyper terminal.
This task was achieved by making read function firstly in which it will read the message
until a space comes. Then we made write function which will write the message on hyper
terminal. In short it will transmit message on the hyper terminal.
If it will not be working like this then it will report an error on the screen.
IC’S USED:
This serial communication was achieved by using MAX232 IC and PIC18F4520 IC. It
was actually communication between PC and microcontroller so we have used RS232
standard. So, we connected the DB9 through PIC MODULE and started communication
with PC.
