    Default first program 12f683

    hello group, this is my first pgm and I'm using 12f683 on breadboard with a pickit2 programmer in MPlAB IDE v.8.46 , not compiling, the compiler chokes
    on this code , what simple thing am I doing wrong. I have no problem programming in ASM to this chip

    OK, I commented out several lines to get the compiler to stop choking and added some asm to get this started

    The files like 12F683.BAS are meant to be left alone. You should be naming your own file xyz.bas or xyz.pbp, or any name to your liking (that does not exist in PBP). Hopefully you made a copy of the file so you can restore 12F683.BAS back to normal.

    You may sometimes have to edit some configs in files like 12F683.inc, but changing configs should be it. Don't write a program there.

    thanks,I'm aware of that copy mistake but I dont know why I have to comment out parts of the .bas file to get it to compile with this simple test code

    That was/is not test code. It is part of the "guts" of PBP just like the *.inc files in the same directory.

    here is the steps I have taken in MPLAB
    1.click project wizard and select 12f683 and save project as test-12f683.mcp
    2. copy file 12f683.bas to folder and rename it test-12f683.bas
    3. click finish and project is complete
    add 2 lines of code
    main:
    goto main

    press f-10 to compile and the program chokes
    then I comment out several items and now it will compile
    this does not seem right

    my code will run on the micro. just want make sure that this is the right way

    No, you are not supposed to put code in, and compile the guts of PBP, like this file. Please re-read posts above.

    Again, that is not a sample or test code. You should not be trying to run it, it is a file PBP needs to help compile code.

    Restore the file to its original state and try one of the smples I linked you to.

    so I should not add the source file 12f683.bas to the project and create an empty file called test-12683.bas in this example?

    You got it.

    Or you can try running one from melabs, like Dave suggested.
    http://melabs.com/samples/LABX4-12F68x/

    Code:
    ' Name        : BLINKX4.pbp
    ' Compiler    : PICBASIC PRO Compiler 2.6
    ' Assembler   : PM or MPASM
    ' Target PIC  : PIC12F683
    ' Hardware    : LAB-X4 Experimenter Board
    ' Oscillator  : 4MHz internal
    ' Keywords    : 
    ' Description : PICBASIC PRO program to blink an LED connected
    ' to GPIO.0 about once a second.
    '
    
    LED Con 0        ' Alias GPIO.0 to LED
    
       ANSEL = 0     ' Set all digital
       CMCON0 = 7    ' Analog comparators off
    
    mainloop:
       Low LED       ' Turn on LED connected to GPIO.0
       Pause 500     ' Delay for .5 seconds
       High LED      ' Turn off LED connected to GPIO.0
       Pause 500     ' Delay for .5 seconds
       Goto mainloop ' Go back to mainloop and blink LED forever
    
       End

    I was using the steps required for an Assembler project

    I'm back with a stupid questions. I want to turn on a led when RC signal is > 1,6ms , but my led is off all time. Please,can somebody explain me why my code not work?

    1000x thx

    code:

    ansel = 0
    wpu = 0
    cmcon0 = 7
    signal var word

    main:

    Pulsin gpio.3,1,signal
    if signal > 1600 then high gpio.0

    goto main
    end

    i solved... the problem was from CONFIG . MCLRE must be off and measured pulse is in 10us.

    #CONFIG
    __config _INTRC_OSC_NOCLKOUT & _WDT_OFF & _MCLRE_OFF & _CP_OFF
    #ENDCONFIG

    ansel = 0
    wpu = 0
    cmcon0 = 7
    signal var word

    main:

    pulsin gpio.3,1,signal
    if signal > 160 then high gpio.0


    goto main
    end

    Hi,

    you also must add in your program the condition for the led to be off ...

    as outputs are bistable kind ... they will stay on the last programmed state, otherwise stated ...
