New member here with MikroC for PIC.And my issue here is that in my code for PIC16F84A is a message that there is not enough RAM for 'active_state'.
Down there is the code that I am working on.
Code: Select all
unsigned short shifter, portd_index;
unsigned int digit, number;
unsigned short portd_array[4];
bit oldstate; // Stara sostojba (flag)
unsigned int broi_1ms, flag_1s; //flag za sekunda, brojac za milisekundi
unsigned int sekundi = 0, minuti = 0;
unsigned int sekundi_desetki=0, sekundi_edinici=0, minuti_edinici=0, minuti_desetki=0;
sbit LED1 at PORTA.B0;
sbit LED2 at PORTA.B1;
sbit LED3 at PORTA.B2;
unsigned int sevenBCD[10] = {
0B0000, //'0'
0B0001, //'1'
0B0010, //'2'
0B0011, //'3'
0B0100, //'4'
0B0101, //'5'
0B0110, //'6'
0B0111, //'7'
0B1000, //'8'
0B1001, //'9'
};
void checkButtons(){
if (Button(&PORTB, 4, 1, 1)) { // Detektira logicka edinica
oldstate = 1; // ja setira flagot i pocnuva da broi
}
if(Button(&PORTB, 5, 1, 1)){ //tasterot STOP e pritisnat
oldstate = 0; //ja vrakja na nula i ne odbrojuva
}
}
void InitTimer0(){
OPTION_REG = 0x82;
TMR0 = 6;
INTCON = 0xA0;
}
void Interrupt(){
if (TMR0IF_bit){
PORTA = 0; // Turn off all 7seg displays
PORTB = portd_array[portd_index]; // bring appropriate value to PORTD
PORTA = shifter; // turn on appropriate 7seg. display
// move shifter to next digit
shifter <<= 1;
if (shifter > 8u)
shifter = 1;
// increment portd_index
portd_index++ ;
if (portd_index > 3u)
portd_index = 0; // turn on 1st, turn off 2nd 7seg.
TMR0IF_bit = 0;
TMR0 = 6;
// if( oldstate == 1)
if(oldstate == 1){
broi_1ms++;
if(broi_1ms > 1000)
{
broi_1ms = 0; // ja vrakjame promenlivata od nula da broi i da broi do 100 pak
flag_1s = 1; // imame izbrojano edna sekunda
sekundi++;
}
if(sekundi == 60)
{
//imame edna minuta(60 sekundi)
//minuti se zgolemuvaat
sekundi = 0;
minuti++;
}
if(minuti == 99)
{
//ako imame 99 minuti vrati gi na 00
minuti = 0;
}
}
}
}
void main() {
InitTimer0();
TRISA = 0x00;
TRISB = 0xF0;
portd_index = 0;
shifter = 1;
do{
sekundi_edinici = sekundi % 10;
portd_array[0] = sevenBCD[sekundi_edinici];
sekundi_desetki = sekundi / 10;
portd_array[1] = sevenBCD[sekundi_desetki];
minuti_edinici = minuti % 10;
portd_array[2] = sevenBCD[minuti_edinici];
minuti_desetki = minuti / 10;
portd_array[3] = sevenBCD[minuti_desetki];
checkButtons(); //gi proveruvame kopcinjata
// updateDisplay();
}
while(1);
}And happy holidays.
