Purpose of Programs • Cgywin is to emulate Linux to run the other programs • Picc lite and Hi-tide are the environment to write your code for programming the microcontroller and converts to Hex • MPLAB is software that allows the codes to be transferred to the microcontroller

Program Code • Motor Control • IR Sensor • Key Debouncer

LED On #include "init.h"// included by C-Wiz #include <htc.h> void main(void) { init();// Function call inserted by C-Wiz while (1){ RA0=1; //TODO Auto-generated main function } }

LED flashing 5 sec int i,k; void main(void) { init();// Function call inserted by C-Wiz while (1){ k=0; while (k<1000){ i=0; k++; while (i<1500){ i++;} } RA0=RA0^1; } }

LED Flashing w / Interrupts // Interrupt service routines #include <htc.h> externint k; void interrupt my_isr(void){ /***** Timer 1 Code *****/ if((TMR1IE)&&(TMR1IF)){ if(k>50) { k=0; RA0=RA0^1; } else k++; TMR1IF=0;// clear event flag } }

Conflict With Loop 5 Second LED flip-flop And Key Debouncer running in main.c

Key Debouncer i = 0; // Wait 20 ms for Button Down while (i < Twentyms) if (1 == RA3) // Button Up / Start over i = 0; else // Button Down /Increment Count i = i + 1;

Motor Control main(void) { init();// Function call inserted by C-Wiz while (1){ RA0=RA0^1; i=0; while(i<10) { i++; k=0; while(k<3000) {k++;}} //CCPR1L= 0b01111111; A=A+1; CCPR2L= A; if(CCPR2L==0XFF) CCPR1L=~CCPR1L;

IR Sensor #include "init.h"// included by C-Wiz #include <htc.h> void main(void) { init();// Function call inserted by C-Wiz while (1){ if(RB2==1) RA0=0; else RA0=1; //TODO Auto-generated main function } }
