ok so posted below is my current script
The problem is that you cant put a function inside another function. I would like to call a function when PORTBbits.RB5=0 (button is pressed) however some of the stuff defined in the var main(var) is needed to run the code in the state# functions.Code:#include <p18cxxx.h> #include <timers.h> //These compiler directives set the compiler options to work with the RE-SBC100. //They should be included in every RE-SBC100 project. #pragma config OSC = HS //This selects the High Speed oscillator, using the //external crystal. #pragma config FCMEN = OFF //This turns off the Fail-Safe Clock Monitor, which //would switch from the external crystal oscillator //circuit to the internal RC oscillator circuit, //should the HS oscillator fail. #pragma config PWRT = OFF //This turns off the Power-up Timer, which holds the //chip in reset mode for about 65ms, making sure //supply voltage is stable before executing //instructions. Turning this on will cause an "Unable //to enter debug mode" error, on the PICKit 2. #pragma config BOREN = SBORDIS //This enables Brown-Out Reset, which resets the chip //if the supply voltage gets too low. #pragma config BORV = 3 //This sets the Brown-Out voltage to the minimum //setting. #pragma config WDT = OFF //This turns off the WatchDog Timer. #pragma config MCLRE = ON //This disables the RE3 input put and enables MCLR //functionality. #pragma config LPT1OSC = OFF //Timer1 configured for high power operation (no //external 32 KHz crystal). #pragma config PBADEN = OFF //PORTB<4:0> pins configured as DIO on reset, instead //of analog inputs. #pragma config CCP2MX = PORTBE //CCP2 Module multiplexed with RB3, instead ofRC1. #pragma config STVREN = ON //This causes the processor to reset in the event of //a stack overflow or underflow. #pragma config LVP = OFF //This disables single supply ICSP disabled. #pragma config XINST = OFF //Instruction set extension and indexed addressing //mode disabled. #pragma config DEBUG = ON //Enable background debug mode on pins RB6 and RB7. #pragma config CP0 = OFF //Code Block 0 protection disabled. #pragma config CP1 = OFF //Code Block 1 protection disabled. #pragma config CPB = OFF //Code Boot Block protection disabled. #pragma config WRT0 = OFF //Block 0 write protection disabled. #pragma config WRT1 = OFF //Block 1 write protection disabled. #pragma config WRTB = OFF //Boot Block write protection disabled. #pragma config WRTC = OFF //Configuration register write protection disabled. #pragma config EBTR0 = OFF //Block 0 table read protection disabled. #pragma config EBTR1 = OFF //Block 1 table read protection disabled. #pragma config EBTRB = OFF //Boot Block table read protection disabled. unsigned char Red = 0; unsigned char Green = 0; unsigned char Blue = 0; unsigned char count = 0; unsigned int MilliSeconds = 8; void WaitMilliSeconds(unsigned int MilliSeconds); void Timer_ISR(void); //This code sets the interrupt vector to point to the Timer_ISR function. #pragma code low_vector=0x18 void interrupt_at_low_vector(void){ //this is an inline assembly code statement _asm GOTO Timer_ISR _endasm } #pragma code //This is the Timer Interupt Service Routine #pragma interrupt Timer_ISR void Timer_ISR(void){ PIR1 &= ~0x02; //clear interrupt for Timer2 if (count < 255){ if (count == Red){ PORTCbits.RC0 = 0; //turn Red LED OFF }//if if (count == Green){ PORTCbits.RC1 = 0; //turn Green LED OFF }//if if (count == Blue){ PORTCbits.RC2 = 0; //turn Blue LED OFF }//if }//if else if (count == 255){ count = 0; //reset count to 0 PORTCbits.RC0 = 1; //turn Red LED ON PORTCbits.RC1 = 1; //turn Green LED ON PORTCbits.RC2 = 1; //turn Blue LED ON }//else if count ++; //increment count }//Timer_ISR int main (void){ unsigned char intensity = 0; TRISC = 0x00; //configure PORTC as output for RC0, RC1, and RC2 //Timer2 triggers the Timer_ISR interrupt after 255 counts PR2 = 0xFF; //Configure and start Timer 2 / Interupt ON / Prescale 1:1 / Postscale 1:1 OpenTimer2(TIMER_INT_ON & T2_PS_1_1 & T2_POST_1_1); //Enable interrupts INTCONbits.GIEH = 1; //needed if using Timer2 INTCONbits.GIEL = 1; //needed if using Timer2 while (1){ //continue forever if(PORTBbits.RB5 == 0) state1(); else if(PORTBbits.RB4 == 0) state2(); else if(PORTBbits.RB3 == 0) state3(); } void state1 (void){ while(1){ for(intensity=0;intensity!=255;intensity++){ Red=(255-intensity); Blue=(255-intensity); WaitMilliSeconds(MilliSeconds); }//for Red=0; Blue=0; for(intensity=0;intensity!=255;intensity++){ Red=intensity; Blue=intensity; WaitMilliSeconds(MilliSeconds); }//for Red=0; Blue=0; if(PORTBbits.RB5 == 0) state1(); else if(PORTBbits.RB4 == 0) state2(); else if(PORTBbits.RB3 == 0) state3(); } } void state2 (void){ while (1){ for(intensity=0;intensity!=255;intensity++){ Red=(255-intensity); WaitMilliSeconds(MilliSeconds); }//for Red=0; for(intensity=0;intensity!=255;intensity++){ Red=intensity; WaitMilliSeconds(MilliSeconds); }//for Red=0; if(PORTBbits.RB5 == 0) state1(); else if(PORTBbits.RB4 == 0) state2(); else if(PORTBbits.RB3 == 0) state3(); } } void state3 (void){ while(1){ for(intensity=0;intensity!=255;intensity++){ Green=(255-intensity); Blue=(255-intensity); WaitMilliSeconds(MilliSeconds); }//for Green=0; Blue=0; for(intensity=0;intensity!=255;intensity++){ Green=intensity; Blue=intensity; WaitMilliSeconds(MilliSeconds); }//for Green=0; Blue=0; if(PORTBbits.RB5 == 0) state1(); else if(PORTBbits.RB4 == 0) state2(); else if(PORTBbits.RB3 == 0) state3(); } } } //this function delays the program for the specified milliseconds void WaitMilliSeconds(unsigned int MilliSeconds){ unsigned int i, j; for(i = 0; i < MilliSeconds; i++){ for(j = 0; j < 255; j++); }//for }//WaitMilliSeconds
I hope I was somewhat Clear. I am fairly new to programing in C and I mostly was cutting and pasting from another code which did something similar only it didnt have any buttons.
THANKS!!
