Serial communication in 8051 microcontroller, Registers and programming
KTU Syllabus, ECT 206 Computer Architecture and Microcontrollers module 4 Serial communication in 8051 microcontroller, registers and programming for serial transmission and reception
1. What are the different registers supporting for serial communication in 8051 microcontroller
2. What are the roles of SBUF register in 8051 microcontroller
3. What are the importance of SCON register in 8051 microcontroller
4. How PCON register can be used in 8051 to double the baud rate of serial port in 8051 microcontroller
5. What are the importance of TI flag in serial transmission
6. What are the importance of RI flag in Serial reception
7. Explain the procedure in transmitting data through serial port of 8051 microcontroller
8. Explain the procedure in receiving data through serial port of 8051 microcontroller
9. Write a program for 8051 microcontroller to transfer “YES” serially at 9600 baud, 1 stop bit, do this continuously
10. Write a program for 8051 microcontroller to transfer letter ‘A’ serially at 4800 baud rate.
11. Write a program to receive bytes of data serially and put them to port 1, set baud 4800, and 1 stop bit.
12. Assume a switch is connected to P1.7 Write an embedded C Program to monitor its status and send two messages to serial port continuously as follows
SW=0, send “NO” with baud rate 28800(28K)
SW=1, send “YES” with baud rate 56K
Assume XTAL = 11.0592 MHz, 8 bit data, 1 stop bit
