Using P18f4580 controller - Write a program in C using Timer0 to generate a square wave with a frequency of 1kHz on PORTBRB5? (Assume XTAL = 20 MHz).
Solutions
Expert Solution
The P18f4580 PROGRAM TO GENERATE A SQUARE QAVE OF FREQUENCE 1KHZ ON PORTBR5 is given as follows:
----------------------------------------------------------------
Program:
#include <p18F458.inc>
ORG 0x00
GOTO START
ORG 0x30
START BCF TRISB,4
MOVLW 0x08
MOVWF T0CON
HERE MOVLW 0xFB
MOVWF TMR0H
MOVLW 0x1E
MOVWF TMR0L
BCF INTCON,TMR0IF
CALL DELAY
BTG PORTB,RB5
BRA HERE
DELAY BSF T0CON,TMR0ON
AGAIN BTFSS INTCON,TMR0IF
BRA AGAIN
BCF T0CON,TMR0ON
RETURN
END
----------------------------------------------------------
So, the program above generates a square wave on PORT RB5.

Write a program that uses a loop to keep asking the user
for a sentence, and for each sentence tells the user if it is a
palindrome or not. The program should keep looping until the user
types in END. After that, the program should display a count of how
many sentences were typed in and how many palindromes were found.
It should then quit.

Write a simple C program to generate a chart of circle
properties. Output chart “iteration” is to be specified by
user input. Your chart will include the radius,
diameter, circumference, and Area values in a single table, and
radius values will range from 0 to 50, floating point values, with
three-decimal-place precision. Table should have all
column entries right-justified and each column will have a heading
above the entries. For example, assuming user enters a
incrementation value of 5, the...
