| I have problem to use Interrupt RB pin4-7c in PIC16LF876 |
 Posted: Sat Dec 25, 2010 3:32 am |
 |
|
I need use PORT B Change Interrupt (pins RB7:RB4), moreover External Interrupt (pin B0) in a PIC16LF876 to active my device from sleep.
This interrupt doesn't work carefully and when I make a pulse in pin B5 no action where down. Please help me ASAP!
My program is :TERMOCUNTERPIC16LF876.c:

Thanks, if you help me and explain me about using PORT B Change Interrupt (pins RB7:RB4) in other simplest code and guide me about using it so it worked carefully.

PortB must be read inside the #int_RB routine, to clear the "Mismatch
condition". This is stated in the PIC data sheet. To do this, add the
code (shown in bold below) to your program.
| Quote: |
// This function reads Port B without changing the TRIS.
int8 input_state_b(void)
{
#byte PortB = getenv("SFR:PORTB")
return(PortB);
}
#int_RB
void RB_isr(void)
{
int8 temp;
PKC++;
if((Command!=Press_Key_First)||(Command!=Press_Key_Second)||(Command!=Press_Key_Third)){Pervius_Command=Command;}
switch (PKC){
case 1: Command=Press_Key_First;PK1=1;PK2=0;PK3=0;break;
case 2: command=Press_Key_Second;PK1=0;PK2=1;PK3=0;break;
default: command=Press_Key_Third;PK1=0;PK2=0;PK3=1;PKC=0;break;
}
OFC=0;
set_timer0(0);
enable_interrupts(INT_TIMER0);
temp = input_state_b(); // Clear mismatch condition on Port B
} |

Do you really have a 2 MHz crystal ? That's very unusual. Or is it
really supposed to be 20 MHz ? If so, edit the #use delay() statement
and also change the fuse from XT to HS.
Are you using the INT output pin of the pcf8563 ? If so, you need a
pull-up resistor on it. You can use 4.7K ohms. |

Dear PCM programmer
thanks
I test it, but noises make interrupt in another pin from B4-B7. I must pull-up Port B but I made my PCB and I don't know why when I use
in my program the port doesn't pull up.
I used 1MHz crystal before but I don't find it in shops and I prefer 2MHz crystal for low consuming power requirements in PIC16LF876 series and I2C baud rate true setting. Also it find in shops!
If you have a better offer I very like to know.
I use PCF8563 Interrupt for wake up from sleep and I pull up it by 4.7K resistor. So I pull up Pin B5 and it connect with Push-pull bottom and noise reduction capacitor to GND.
Thanks for your help.

| Quote: | I must pull-up Port B but I made my PCB and I don't know why when I use:
port_b_pullups(1);

Then make a small test program and study how to use the
port_b_pullups() function.
I looked in your program for the port_b_pullups() line, which you say
you have in there. I didn't find it. But I did see this problem:
| Quote: |
void ReportTSC(int32 inp){
int8 i,dig[4],temp;
dig[0]= make8(inp,0);
dig[1]= make8(inp,1);
dig[2]= make8(inp,2);
dig[3]= make8(inp,3);
temp=Sleep_Priod_Division_Reg;
putc(I_am_ready);
for(i=0;i=3;i++)putc(dig[i]); putc(temp);
}
|
What does that line do ? How can "i=3" work ?
Here is a test program to test that line of code:
| Code: | #include <16F877.H>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
//==========================================
void main()
{
int8 i;
for(i=0;i=3;i++) putc('A');
while(1);
} |
Here is the output:
| Quote: | AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA |
Your code does not work correctly.
You need to study "for loops" in the C language and learn how to make
a correct for() statement. |

I placed corrections that you offered in my program. Thanks for your attention. but in ccs c manual says that: | Quote: | for
For is also used as a loop/iteration statement.
The syntax is
for (expr1;expr2;expr3)
statement
The expressions are loop control statements. expr1 is the initialization, expr2 is the termination check and expr3 is re-initialization. Any of them can be omitted.
Example:
for (i=1;i<=10;++i)
printf("%u\r\n",i); |
I think termination check means that when I come to expr2 this loop is end of screwing and when this loop were end next line go runs.
pleas help me that what of these:
| Code: | | for(i=0;i<=3;i++)putc(dig[i]); |
or
| Code: | | for(i=0;i>3;i++)putc(dig[i]); |
is ok?

Make a test program. Test it with each of those lines of code.
Then you can see what each line does.
You can test it with the MPLAB simulator:
See this post for instructions on how to use the "UART1" feature of the
MPLAB simulator to display serial output in the MPLAB Output Window:
