    Question Output PIC module

    Hi experienced All:
    I am trying to check advantages and disadvantages
    of Three PICs Architecture.
    I appreciate any comments and thoughts how to improve
    program below that will serve output functions
    in Output PIC.
    Thank you for your time.
    Best Regards,
    Leonid
    P.C.PICBasic Pro Compiler tell: success: 995 word used
    My inner filling tell me that is possabilities to improve
    this program.

    as there's a lot of jump here, there elsewhere, lalaland, i think you should build a flowchart to help you to structure everything and avoid so many jumps. Well it's my own opinion.

    One thing Jump to my face ... the use Of CALL !!!! usually we use GOSUB with a RETURN.

Using CALL, a Label in an assembly language section can be accessed that is otherwise inaccessible to PicBasic.
    don't give up!

    Question Output PIC module

    Hi Steve:
    Thank you very much for your time.
    I got something new in learning PICs.
    Remark:
    Purpose for this program is to cteate rotating adjustable magnitic field that can be used to drive steppers or brushless motors and by cutting sequence
    of pulsout statements does not really impove program.
    Second reason is to create thermal control unit for 6 heaters of furnace
    that are located on 1-top,2-bottom,3-lift and 4-right side, 5-back wall and 6-sliding front door.Because of temperature difference inside chamber
    sequence of pulses will help to create equal isothermal properties iside of chamber.
    Or if you like model of autonomous flying or moving vehicle it is part of right remote control unit.
    As you see It looks like universal unit.
    If I correctly understand your remark:
    pbpin var byte
    pulsout pbpin, w9
    I am able to run PWM, Pulsout, Serout, Serin, Output .... statements
    on pre-programmed numbers of output pins in one shot?!
    Second question about "!!!! usually we use GOSUB with a RETURN.".
    I have 7 program each has two submodules rotate left/right and each has
    two procedure to calculate W9 value.
    In sum about 28 Gosub and 28 Return statements. My guess is here will be real problem with wrong switching.
    In Visual basic it is not problem,In C++ and Visual Basic It is simple to encapsulate problem in modules and classes.
    What can I do in PICBasic to avoid mistakes?
    Thank you for your help again.
    Best Regards,
    Leonid

    Yes and no. You're able to send pulse on a single pre determined PIN for a w9 duration in one shot. Doing some Sub with common called statement or block of statement,l help to reduce the final code size.
    Second question about "!!!! usually we use GOSUB with a RETURN.".
    I have 7 program each has two submodules rotate left/right and each has
    two procedure to calculate W9 value.
    In sum about 28 Gosub and 28 Return statements. My guess is here will be real problem with wrong switching.
    If you don't have much than 4 nested gosubs, it shouldn't cause any problems. If you have more than 4 nested gosubs, your program may branch somewhere else than you expect.

    You can have as much as you want of nested GOTO. As it don't use the STACK... no harm at all.

    There's no trick, no magic formula to avoid problems. As in all programming language, you should avoid too many jump here, there elsewhere and have a good program structure. A flowChart could help to figure out the whole thing. Few gosub line placed one after the other is not a too much bad pratice.
    Code:
    Gosub DoThis
Gosub DoThat
Gosub DoSomethingElse
    But the use of nested gosub should be done with care.

    Smile Output PIC module

    Hi Steve:
    Thank you very much for showing the art of programming.
    With your help I was able to reduce number of compiled words
    from 995 to 412.
    Looks like I can write another program up to 500+ compiled
    words and to add to same PIC flash memory.
    I still have one question for you:
    PortB=b6 'pin0-pin7
    Pulsout 6, w9
    Does pins 0,1,2,3,4,5 and 7 not changing their values b6.0,b6.1,b6.2,
    b6.3,b6.4,b6.5, and b6.7 during pulsout on pin 6?
    Or need to use some kind of trick to hold their value during
    pulsout on pin 6.
    Below is corrected program.
    Best Regards,
    Leonid

    still have one question for you:
    PortB=b6 'pin0-pin7
    Pulsout 6, w9
    Does pins 0,1,2,3,4,5 and 7 not changing their values b6.0,b6.1,b6.2,
    b6.3,b6.4,b6.5, and b6.7 during pulsout on pin 6?
    Or need to use some kind of trick to hold their value during
    pulsout on pin 6.
    No Pulsout should affect only one pin. The other, SHOULD stay as is.
