Phase angle control of thyristor w/ PIC18F
PostPosted: Tue Sep 02, 2014 1:40 am     Reply with quote
Hello,

For the following code, I got some errors:

#include <18F452.h>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)

unsigned char FlagReg;
sbit ZC at FlagReg.B0;

void interrupt(){
if (INTCON.INTF){ //INTF flag raised, so external interrupt occured
ZC = 1;
INTCON.INTF = 0;
}
}

void main() {
PORTB = 0;
TRISB = 0x01; //RB0 input for interrupt
PORTD = 0;
TRISD = 0; //PORTD all output
OPTION_REG.INTEDG = 0; //interrupt on falling edge
INTCON.INTF = 0; //clear interrupt flag
INTCON.INTE = 1; //enable external interrupt
INTCON.GIE = 1; //enable global interrupt

while (1){
if (ZC){ //zero crossing occurred
PORTD.B0 = 1; //Send a 1ms pulse
delay_ms(1);
PORTD.B0 = 0;
ZC = 0;
}
}
}

How can I fix the mistakes? I'm open to other code snippets as well.

Seriously, write in CCS....
Read the manual.

What you have is basically assembler, and most of it unwanted.
Also use the code buttons.
Code:

#include <18F452.h>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)

int1 zc=FALSE; //only use all capitals for #defines

#INT_EXT
void interrupt(void)
{
   zc=TRUE;
} //the compiler handles testing what interrupt, and clearing the interrupt

void main(void)
{
    output_b(0); //set port b all low
    output_float(PIN_B0); //RB0 input for interrupt
    output_d(0); //set port d all low
    ext_int_edge(H_TO_L); //falling edge interrupt
    clear_interrupt(INT_EXT); //clear interrupt
    enable_interrupts(INT_EXT);
    enable_interrupts(GLOBAL); //enable interrupt
   
    while (TRUE)
    {
        if (zc)
        { //zero crossing occurred
           output_high(PIN_D0); //1uSec more like it....
           delay_us(1);
           output_low(PIN_D0);
           zc=FALSE;
        }
    }
}

As written this will just pulse the thyristor 'on' a few uSec after the zero point. To actually give dimming, you'd have to delay when the pulse occurs from this point.

Sorry, I posted the wrong code. Here comes the actual code:


#include <18F452.h>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)

unsigned char FlagReg;
sbit ZC at FlagReg.B0;

void interrupt(){
if (INTCON.INTF){ //INTF flag raised, so external interrupt occured
ZC = 1;
INTCON.INTF = 0;
}
}

void main() {
PORTB = 0;
TRISB = 0x01; //RB0 input for interrupt
PORTA = 0;
ADCON1 = 7; //Disable ADC
TRISA = 0xFF; //Make all PORTA inputs
PORTD = 0;
TRISD = 0; //PORTD all output
OPTION_REG.INTEDG = 0; //interrupt on falling edge
INTCON.INTF = 0; //clear interrupt flag
INTCON.INTE = 1; //enable external interrupt
INTCON.GIE = 1; //enable global interrupt

while (1){
if (ZC){ //zero crossing occurred
delay_ms(2);
PORTD.B0 = 1; //Send a pulse
delay_us(250);
PORTD.B0 = 0;
ZC = 0;
}
}
}


And error list:

Same comment applies to this.

Look at what I have posted. Just add your 2mSec delay before sending the pulse. 250uSec is still too long. If you need more than 10USec, then there is something badly wrong with the circuit.

this....

sbit ZC at FlagReg.B0;

... doesn't look correct to me

Yes, he is using a completely different language, where you define a variable, and then access bit fields in it.

He copied the code from here:
http://tahmidmc.blogspot.com/2012_10_01_archive.html

He has also cross posted his question to:
http://www.microchip.com/forums/m819084.aspx

He doesn't realize that CCS != MikroC != XC8, etc.

He thinks he can take code for one compiler and drop it in another
and that it will compile.

I hoped he might look at what I posted, and see how the different commands are used. Little hope though....
