    Post The interrupt Way

    Hi, Charudatt

    Here it is :





    @ __CONFIG _INTOSC_OSC_NOCLKOUT & _WDT_OFF & _LVP_OFF & _PWRTE_OFF & _CP_OFF & _BODEN_OFF

    DEFINE NO_CLRWDT 1
    DEFINE INTHAND _Blink


    CMCON=7
    VRCON=%01101100 'VRCON bit7 is OFF for no current drain
    OPTION_REG.7 = 0 ' ENABLE INTERNAL PULLUPS
    Porta = 0
    PORTB = %11110001
    Trisa = %11110011
    Trisb = %11111111

    LED VAR PORTA.2
    SleepLed var PORTA.3
    Dummy var byte

    '
    ' PIC Low-Power Sleep Routine
    ' ---------------------------
    '
    ' Set Sleep Interrupts
    ' --------------------
    INTCON=%10011000 ' Interrupt Control Register
    ' 7=0 - GIE - Global Interrupt Enable
    ' 6=0 - PEIE - Peripheral Interrupt Enable
    ' 5=0 - TOIE - TMR0 Overflow Interrupt Enable
    ' 4=1 - INTE - RB0/INT Enable
    ' 3=1 - RBIE - PORTB change interrupt Enable
    ' 2=0 - TOIF - TMR0 Overflow Flag
    ' 1-0 - INTF - RB0/Ext Interrupt Flag
    ' 0=0 - RBIF - PORTB Interrupt Flag

    OPTION_REG.6 = 0 ' 1=RB0 Rising-Edge Trigger, 0=Falling-Edge Trigger

    CYCLE:
    '
    ' Reset Interrupt Flags
    ' ---------------------

    INTCON.1 = 0 ' Reset RB0 Flag
    INTCON.0 = 0 ' Reset PORTB change Flag
    INTCON.7 = 1
    '
    ' Sleep
    ' -----
    LOW LED

    High Sleepled

    @ SLEEP
    @ nop

    Blink:

    Dummy = PORTB
    Pause 100 ' Needed for system Wake-Up

    LOW SleepLed

    HIGH LED

    While ( PORTB >> 4 ) <> %00001111
    Wend

    PAUSE 200

    PAUSE 5000
    LOW LED

    GOTO CYCLE

    END



    As you see it's not so different from the "non interrupted" way ...

    But, IF I correctly understand Mel ( one more time, Mel : You're the one and Only ... !!! - no sexual meanings hidden ( LOL) ) , the interrupt way could fit both 628 and 628A ...

    I must say I used a 16F628-04 batch N° 0145H9F for tests ( I do not have any 628A ... but will run a try with a brand new 648A.

    ********************************************
    ********************************************
    A little "bug" in the "non interrupted" listing ... to correct:

    TRISB must be % 11111111 ... instead of % 01111111

    I was wondering why PortB.7 was inactive .... LOL !!!


    Have fun, and read you soon

    regards

    Alain

    Talking Humour ...

    Those who really followed this thread have surely noticed there could have been other lines inserted between :

    @ SLEEP
    @ nop

    AND ...

    Blink:

    didn't you ??? ....

    Hello Alain,

    Do you mean:
    @ SLEEP
    @ nop
    snore
    Blink:
    turn-over
    @ SLEEP

    Then again, sometimes I "just don’t quite get it"...

    <body onload="setInterval('blinkIt()',1000)">

    <script type="text/javascript">
    function blinkIt() {
    if (!document.all) return;
    else {
    for(i=0;i<document.all.tags('blink').length;i++){
    s=document.all.tags('blink')[i];
    s.style.visibility=(s.style.visibility=='visible') ?'hidden':'visible';
    }
    }
    }
    </script>

    <blink>@ NOP</blink>

    @nap will just define a label
    nap without the @, is a PBP function, and it's not the same as ASM
    <blink>@ NOP</blink>

    A half hearted compile of your code (Alian) for the 16F873A gave an error with DEFINE INTHAND _Blink.

    I changed it to DEFINE INTHAND Blink and it did not come out of sleep (I presume) the same code compiles OK for the 16F628A.

    I am sorry , I was busy with some other job, but today I shall try your code for the intended chip and post results.

    Thank you for all your help,

    regards

    Talking Rtfm !!!

    Hi, Charudatt

    See chapter 9.3 ...

    your device ( 16F873 ) has two mem. pages ... 16F628 only has ONE.

    What does PbP for ASM Interrupts ???

    What do you have to reserve as variables room ???


    TWO beers now !!!

    Cheers

    Alain

    C'mon Mister_e, you can do better than that! - show us all some of your "real" java skills, like scrolling some 3D text with user definable parameters.

    Hi, Adam

    Snore never happens ... might be a LABEL to call before !!!
