While(RC0=1) //if PORTC pin 0 = 1, If button is released

Seq(15) //call function 4 with parameter 15 Seq(7) //call function 7 with parameter 7 Seq(3) //call function 3 with parameter 3 Seq(1) //call function 1 with parameter 1 If (RC0=0)//if PORTC pin 0 = 0, If button pressed While(1) //define While loop for continuous operation OPTION_REG= 0b00000000 //Enable pull up R on port C TRISD = 0x00 //Instruct the MCU that all pins are output TRISC0 = 1 //Define PORTC pin 0 is used as input for push button. PORTD = get << j //LED move Left Sequence #define _XTAL_FREQ 20000000 //define crystal frequency to 20MHz this loop executes seven times and every time left sift data by one bit Now First shift the register value to left by ‘1’ with for loop for (int j=0 j=0 j–). First of all we need to declare a function seq(char get) used to right shift and left shift values passes to this function as an argument. same way we will used for Loop in this project also but with shifting the register value left and right using function. In my last tutorial we have used for loop to blink LED with delay. Note we can use IO bits line by line in code to blink the multiple LED but in this case code becomes lengthy. Refer below different I/O pins available on our PIC16F1517 for your better understanding. Here we will define PORTD as output and PORTC bit 0 as input. To execute this project we need 8 digital output from PIC controller to drive the LED and one Digital Input to accept the push button response. Request look at once to get basic understanding about the components. The basic details of LED Functioning and Push Button operation explained in my previous tutorial on Arduino. So I am planning 8 number of LED’s to be blink in sequence and Push button to start the sequence. #pragma config LVP = OFF // Low-Voltage Programming Enable (High-voltage on MCLR/VPP must be used for programming) #pragma config LPBOR = OFF // Low-Power Brown Out Reset (Low-Power BOR is disabled) #pragma config BORV = LO // Brown-out Reset Voltage Selection (Brown-out Reset Voltage (Vbor), low trip point selected.) #pragma config STVREN = ON // Stack Overflow/Underflow Reset Enable (Stack Overflow or Underflow will cause a Reset) #pragma config VCAPEN = OFF // Voltage Regulator Capacitor Enable bit (VCAP pin function disabled) #pragma config WRT = OFF // Flash Memory Self-Write Protection (Write protection off) #pragma config FCMEN = ON // Fail-Safe Clock Monitor Enable (Fail-Safe Clock Monitor is enabled) #pragma config IESO = ON // Internal/External Switchover (Internal/External Switchover mode is enabled) I/O or oscillator function on the CLKOUT pin) #pragma config CLKOUTEN = OFF // Clock Out Enable (CLKOUT function is disabled. #pragma config BOREN = ON // Brown-out Reset Enable (Brown-out Reset enabled) #pragma config CP = OFF // Flash Program Memory Code Protection (Program memory code protection is disabled) #pragma config MCLRE = ON // MCLR Pin Function Select (MCLR/VPP pin function is MCLR) #pragma config PWRTE = OFF // Power-up Timer Enable (PWRT disabled) #pragma config WDTE = OFF // Watchdog Timer Enable (WDT disabled) #pragma config FOSC = HS // Oscillator Selection (HS Oscillator, High-speed crystal/resonator connected between OSC1 and OSC2 pins)
