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

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.

don't give up!

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.

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.

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

Quote:

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.
