Motor Stepper Example

[Nozapo]

Whilst this was written some time ago, the subject crops up every now and again, so may be useful to some folks. Written for a 4-wire Stepper Motor...

Melanie

Hello Mel, Everyone,

I`d like to know how to get the code into the chip, (might sound silly), but it doesn`t seem to want to compile in any of the software.

I`ll more than likely be using a 6 wire stepper motor, but shouldn`t matter, as there`s still only 4 to drive the coils, the other two are power wires.

Have tried a few things, like using PortC outputs on pin 5,6,7,8 instead, that`s just by changing the portB to portC, no go either.

Other items would be,
9&10 for LED output, 11 for step, 12 for Direction, 13 for Enable, pins 1&2 to pull hi / low, via jumpers or 2 switch DIL component. (1on/2on, 1off/2on, 2on/1off, 1off/2off)

Any assistance at all would be appreciated immensley.

Thank you.

What version of PicBasic Pro do you have? Melanie's example from post#1 seems to compile fine over here. I tried the 16F877.

Hi Scalerobotics,
Thanks for the other couple of links, I`ll have a look.
One of the latest versions, but see the attachment one screen capture of BasicPro & one from Picaxe compiler and their respective messages.

Note, I don`t have any headers etc. just copy pasted the code as is, oh, and with different port#`s, which hasn`t made any difference to the error messages.
In any case, the 16F877 isn`t any good to me, my requirements/specs are for a 14 pin Pic.
I`d have to reconfigure the code to suit again, so there`s Picaxe14M/2, 16F684, 16C505, 16F505, 16F676,etc, or if I`m not fussy, I can get really universal and put one of those AVR chips in if they`re easier to configure, that way both camps can enjoy (a balance in the force, perhaps ha,ha).

Thanks again

If you are not using Pic Basic Pro the examples from this forum will not work. Nor will they work for an AVR chip or picaxe.

Thank you.

May I understand you use a dedicated driver circuit, Allegro 3967 i.e. ??? perhaps some existing satellite Module ???

Hello Alain,
Not quite sure of your response, so as I understand it, I`ll respond...
The Allegro won`t fit either,( but having a look at it, you`ve given me another idea, on which I must think on).
Just for the following unit I have constructed, 3 separate ICs, not "networked".
looking at a few alternatives.


Thank you
