●Displaying Constant Scripts on 2x16 LCD

Here is the program written by using CCS C.

#include <16f628.h>

#fuses NOPROTECT, NOWDT, NOLVP, NOMCLR, INTRC_IO

#use delay(clock=4M)

#include //It is essential for using LCD in our program

void main(){

lcd_init(); //Must be called before any other function

while(1){

lcd_gotoxy(1,2); //To set write position on LCD

lcd_putc("Sezgin Secil"); //Displaying script on the next position of the LCD

}

}

Note: For using LCD in our designs, we should use lcd.c file. It is used for both Port B and D. So, if we want to use it for Port B, we need a modification in the lcd.c file:

Find LCD.C file in drivers, open it, find the line that consists of "//define use_portb_lcd TRUE" and change that as "define use_portb_lcd TRUE". All you need to do is removing the the double slash at the beginning of the command.

●Counting from 9 to 0 on 7-Segment Display

Here is the program written by using CCS C.

#include <16f628.h>

#fuses NOPROTECT, NOWDT, NOLVP, NOMCLR, INTRC_IO //Adding internal oscillator with INTRC_IO and MCLR makes possible to reset but with NOMCLR there is no need to connect anything that pin

#use delay(clock=4M) //To define the delay time correctly

void main(){

char series[]={63,6,91,79,102,109,125,7,127,111}; //Defining the decimal values of total logic values on 7-segment display

char x=9; //To start the loop from 9nd value

while(1){

do{

output_b(series[x]); //To show the desired value on 7-segment display

delay_ms(250); //Delay for observation

x--;

}while((x+1)); //To end the loop

x=9;

}

}

●Flashing LED Controlled by a Button

Here is the program written by using CCS C.

#include <16f628.h>
#fuses NOPROTECT, NOWDT, NOLVP, NOMCLR INTRC_IO //Adding internal oscillator with INTRC_IO and MCLR makes possible to reset but with NOMCLR there is no need to connect anything that pin
#use delay(clock=4M) //To define the delay time correctly

void main(){
while(1){ // For an endless loop
if(!input(pin_a0)) //Checking the input of the first pin of port A
output_high(pin_b0); //If input is low, LED flashes
else output_low(pin_b0); //If input is high, LED doesn't flash

}
}
