    Yes, 22uF capacitor can be used instead of 20uF.
    (That is if you ment using it in dejan BOX)

    The capacitor is there just to stabilize power output from LPT, size of capacitor is not so critical here.

    I have tested your hex with a pic 16F628 /04 but it won't work.
    Do I need a pic 16F628 /20 or my is compatible?

    Thank You
    _Bye_

    Hi!

    If dejan1.04 receives serial nr. from BOX, but pressing F1 gives bad connection, you are propably using wrong type of crystal.

    Box MUST be run with 8MHz crystal to make MBUS work.

    If you are using 4MHz crystal, PC receives data from box but communication to phone won't work.

    Hi

    When using F628 I think MCLR config bit (Master Clear Enable) should be on.
    In F628 MCLR pin can be configured also as digital I/O (RA5), this feature wasn't available in CE625.
    If MCLR config bit is disabled, PIC uses internal RESET, and correct RESET of device may be uncertain.

    If I had F628 chip I would try this kind of configuration:
    (WDTE) : Disabled
    (PWRTE): Enabled
    (MCLR) : Enabled
    (BODEN): Disabled
    (LVP) : Disabled
    (CP) : Disabled

    (At this moment I have to run HEX in MPLAB simulator, when analysing results seems that dexF628.hex does everything that dex0.hex does, but using different EEPROM routines.)

    I also visited other GSM-forum, and many people there wrote that they have same kind of problems with original dex0.hex when using CE625.

    This is quote from other forum:

    "Run as "cwsdpmi -s- -p" before running flasher...
    If you don't have much physical ram run as "cwsdpmi -p

    About M2BUS for me it only does not work in a DOS box running on Windows...
    WinDLS works great, so MBUS works for me..."


    I belive we can find the solution, it can't be far away since on some PC's BOX seems to send serial number.

    Ciao o-Mast
    scusa il ritardo ma non ero in sede
    nel bios ho provato tutte le differenti possibilita' epp ecp e bidirezionale comunque penso che il problema sia nella comunicazione seriale con il telefono cioe' tra il pic ed il telefono ci lavoro e poi ti dico.
    comunque e' molto strano che veda il box ma non il telefono.
    Sono di Ravenna

    Ciao,
    non ci posso credere che siamo tre italiani su questo forum; Comunque caro o_Mast io ho flashiato la F628 con le indicazioni di MTL:
    (WDTE) : Disabled
    (PWRTE): Enabled
    (MCLR) : Enabled
    (BODEN): Disabled
    (LVP) : Disabled
    (CP) : Disabled
    ... e a quanto ho visto il box viene riconosciuto correttamente... Purtroppo ancora non ho collegato il cavetto che va al telefono quindi non so se la comunicazione con il telefono č funzionante, ma tra computer e box tutto ok...
    A proposito la mia porta parallela č settata come normal e io non ho usato nessun cavo per collegare il box alla porta del computer... Quindi se fossi in te controllerei bene l'assemblaggio del box, e altro quali il cavo ad esempio di collegamento (se lo usi)...
    Comunque fammi sapere se riesci a falo funzionare...
    Gianni.

    (P.S. credo che il settaggio suggerito da MTL e cioč MCLR Enable sia molto importante.... in quanto configura il piedino di reset della pic)


    Dear MTL,
    Your Hex file works fine i think, because i've seen that the program known the box... but i don't try to connect the box to the phone again...
    Now Many thanks for all... You have done a big work...
    B.R.
    Gianni
