| PIC18F4550 and INT_EXT2(RB2) |
 Posted: Mon May 19, 2014 6:06 am |

Hello,
I'm working on PIC18F4550 with PCW Ver 4.134
I would like to use RB2 as an external interrupt wich I detect the edge Low to high or high to low.
My software is doing some voltage and current measurements, generates fault and warning and commands
This code is working well without interrupt but the timing is not good. Normal!
If I use the interrupt INT_EXT2, it's very strange because if I power my board with RB2=0, it's OK.
But If I power my board with RB2=1, it's like BIAS_ON() was executed an half: Only one command is ON on the 6 commands. After if RB2 goes LOW and after high, it's OK.
Does someone have an idea to explain that and to help me?
Thanks,
Fabrice

Classic 'read the data sheet'....
Setting the 'edge' for an interrupt, can always potentially result in the interrupt being triggered.
The sequence has to be:
1) set the edge.
2) clear the interrupt.
3) enable the interrupt.
As a further comment, disabling the interrupt inside the handler is pointless. The hardware disables the interrupts. |

Thanks for your answer,
So I changed I little bit my code in the #INT_EXT2 :
I deleted disable and enable interrupt,
In the main, in the init, I changed the order of initiate the interrupt:
| Code: |
clear_interrupt(INT_EXT2);
enable_interrupts(INT_EXT2);
enable_interrupts(global);
|
but it's not working.
| Code: |
#INT_EXT2
void ext2_isr()
{
// disable_interrupts(INT_EXT2);
if(input(TRIG))
{
bias_ON();
bit_set(status3,0); // STATUS TRIG =1
ext_int_edge(2,H_TO_L);
}
else
{
All_bias_OFF(); // Force toutes les regulations à 0
bit_clear(status3,0); // STATUS TRIG =0
ext_int_edge(2,L_TO_H);
}
clear_interrupt(INT_EXT2);
// enable_interrupts(INT_EXT2);
}
void main()
{
setup_adc_ports(AN0_TO_AN6|VSS_VREF); //VREF=4.096V. Attention à la mesure de AN0 à A11.
setup_adc(ADC_CLOCK_INTERNAL);
setup_psp(PSP_DISABLED);
setup_wdt(WDT_OFF);
setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
setup_timer_3(T3_DISABLED|T3_DIV_BY_1);
setup_comparator(NC_NC_NC_NC);
setup_vref(FALSE);
usb_init();
init_LED(); // Test LED ON puis OFF 100ms
All_bias_OFF(); // Force toutes les regulations à 0A
init_var(); // Recuperation données EEPROM
init_BUFF(); // init buffer RS232/USB
init_CNA();
int_count=INTS_PER_MIN; // Timers pour clignotement
set_rtcc(65279);
setup_counters( RTCC_INTERNAL, RTCC_DIV_256);
enable_interrupts(INT_RTCC);
if(input(TRIG))
{
bias_ON();
bit_set(status3,0); // STATUS TRIG =1
ext_int_edge(2,H_TO_L);// etat initial si TRIG=1 -> detecte un front descendant
}
else
{
All_bias_OFF(); // Force toutes les regulations à 0
bit_clear(status3,0); // STATUS TRIG =0
ext_int_edge(2,L_TO_H);// etat initial si TRIG=1 -> detecte un front montant
}
clear_interrupt(INT_EXT2);
enable_interrupts(INT_EXT2);
enable_interrupts(global);
while(true)
{
EnTrans_Shunt=0b10111110;
/* if(input(TRIG))
{

bit_set(status3,0); // STATUS TRIG =1
}

{

How does the 18F4550 run at 100 MHz when the data sheet says it
runs at 48 MHz max ? |

You are right,
I started with CCS USB development kit and I don't know where I've found this. It's a big mistake.
So I correct my software :
| Quote: | #fuses HSPLL, NOWDT, NOPROTECT, NOLVP, NODEBUG, USBDIV, PLL5, CPUDIV1, VREGEN
#use delay (clock=48M) |
But the result is the same... |

Realistically, you need to learn how to debug....
Nobody is going to actually read through your code in it's entirety (far too large). That includes _you_!....
The key with debugging is to cut code down into smaller chunks, till problems are isolated, allowing you to find errors.
Now scanning through your initialisation, two problems have already been spotted by posters here, but the core fault still remains....
Start much smaller. Learn to write in sections, and get each part working on it's own. Then build using these smaller 'bricks'. |

That's what I'm trying to do this morning.
To start with a small code and after finding the bug... |

So now it's ok. The trouble was elsewhere not in the interrupt.
Thanks for your help
