I am sending the "missing file "stepper.spin" ". thought this was included with the main files. Hope this helps. I started learning to do most of those mini programs with " Propeller Education Kit Labs " way back in 2008, but now no time , must get this system running so i can photograph the stars. Also I might add , I can run both motors with the auto inputs but that uses the guide camera and a separate computer and the "Costar" program, or a separate keypad.

Oh, I see, You are in a hurry.
Since 2022.
You don't have the time to send the right files or convert the *.sch into a pdf, that someone can have a look at it.
And you don't have the time to have a look at the stepper.spin, to see how reverse direction is supposed to work. And just try it.
Dave Hein has written this file for you. He has been a very friendly man.
In this special case a somewhat silly approach might be helpful for you:
You can reverse the running direction a step motor, if you change the polarity of one of it's phases. So you can add a 2 pole switch for each motor.
Of course this picture is only meant to show how a dual pole switch can invert the polarity for a load. In your case the load would be one phase only and the supply must come from the step motor driver. Just insert the switch into the lines from driver to a phase.

On question one; I downloaded the link into my computer and opened the file manager in the task bar and went to download files and double left click and file opens.( I use windows10 for my OS).
That was a good one. Reading you old posts I think, that you might have installed KiCad?
)))
Good luck with the stars! Please post a nice picture perhaps of Venus. Though Mars might be more opportune these times.

Ok KiCad can open this schematic. I installed it. Is this file the true last version?
You might want to have a close look at the supply for the eeprom, which is unregulated!
I thought you would use FLIP modules????
Still the wrong file , try this on for size. I started out back in2012 using the "Flip" modules but I kept damaging them , then a poster told me to use the individual components instead. The processor is cheaper to replace.
Looking back at your drawing of the switches , the L293 switches directions according to the polarity of the logic on pins 3 and 13 of the CD4030 chip in the motor driver board . A - RA_RATE or -DEC_RATE should reverse the direction of the motor associated with the RA or DEC . also I added dh_stepper for the new file
Hi,
so this schematic is, what you intend to have in hardware?
There is at least one error at an open pin5 of one of the 4030.
I would have to make a logic table to understand the logic of the 4030 + 4027.
For my feeling there also must be a few additional capacitors in the schematic!
Haha, the ...bs19.spin does not compile either.
So this is not the file matching your error description: "When I press a button on the control pad , both motors run and they don't reverse when I press reverse direction buttons." Post 571.
You seem to think, that we forum members are some kind of clairvoyants (just learned a new word) who can guess what you are doing or what software you use or what hardware you really have or if you "kept damaging them".
I sent you the switch schematic, because as you have no time to debug your program or check if you send the right ones. You could just insert the switch and get going, if you manage to find the right software.

This program does not change the Direction output.
Perhaps better:
This program does not effect the Direction outputs?

I would just get it done.

Hm, the wrong file here too?

I see what you mean, I extended the trace to the VO line and removed the junction from the VI line.
