<div class="markdown_content"><p>Hello! Since I saw here has been questions regarding GPIO it should be proper to post a question here about connecting IO-s to raspi stepper library. <br/> I use different type of raspberry (Revolution pi). Revolution pi I/O-s are not configured under GPIO tab as for standard raspberry. Raspistepper library supports only Dword value for pins. How could I solve my problem. I have IO list and it is mapped by using some name: "outputW.0" for example. I need to connect it with raspistepper library but had found no solution jet for it </p></div>

<div class="markdown_content"><p>Hello.<br/> Tell me how to properly configure the drive for a circular stepper motor? In the first picture, I showed the normal setting, the motor is spinning. But if you change the motor type to circular, then it does not work. Tell me what is the reason? Is this a problem in the library?<br/> Thank you.!</p></div>

<div class="markdown_content"><p>Hello everybody,😀<br/> I am carrying out my project and continue in this discussion.<br/> I haven't been able to get a soft motion limit switch to work yet, but for now I can do without it.<br/> now I need help on controlling a DC motor through codesys, do you think if I connect a BTS7960 to a raspberry I can control it with softmotion?<br/> I put some photos to better understand (the motor is a 895 360w, so with a very high load).<br/> I trust in your precious help.🙏</p></div>

<div class="markdown_content"><p>Hi,<br/> yes sorry my fault - this is true - only possible if this driver is not used-<br/> it might work if you use a PIFACE2 - I think this IO's are connected by SPI<br/> see the schema here:<br/> <a href="https://2.bp.blogspot.com/-O8fqpxHsuFQ/UhXwZzNJT7I/AAAAAAAAIVw/jhAsMoB2Ssg/s1600/Pi-face-digital-schematic.png" rel="nofollow">https://2.bp.blogspot.com/-O8fqpxHsuFQ/UhXwZzNJT7I/AAAAAAAAIVw/jhAsMoB2Ssg/s1600/Pi-face-digital-schematic.png</a><br/> but anyway I did not have checked it in real.</p></div>

<div class="markdown_content"><p>Hello ,<br/> in fact that's what I want to do, but reading the guide of this link <a href="https://forge.codesys.com/drv/sm3raspistepper/home/Home/">https://forge.codesys.com/drv/sm3raspistepper/home/Home/</a>, it says that the GP i / o cannot be used together with softomotion, I don't know if there is an alternative way to connect other inputs / outputs besides the engines.</p></div>

<div class="markdown_content"><p>Hello eschwellinger!</p> <p>I kind of have the same issue. Running three stepper motors with help of Softmotion and Raspberry Pi 4.<br/> I want to use some additional outstanding GPIO's for limit switches and/or other DI/DO's. Seems like when I'm running softmotion, my whole<br/> GPIO bus is getting disabled (not sure if softmotion is causing this issue). The GPIO is marked with a red <br/> triangle in the Device Tree and have status "Bus is not running" and "GPIOs: Not Running"</p> <p>My question is: Is Softmotion blocking me to use the other outstanding GPIO's? <br/> Is it possible to add limitswitches (DI/DO's) while running softmotion?</p> <p>Note: I have connected one limitswitch to GPIO4 for testing and mapped the IO correctly (working when creating a blank program without softmotion).</p> <p>Se pictures attached.</p> <p>Hope you are able to help and clarify.. :-)</p> <p>Regards</p></div>

<div class="markdown_content"><p>you need to set the GPIO's and map them.<br/> Then use these Inputs at the SMC_homing fb</p></div>

<div class="markdown_content"><p>Thanks for the time you are dedicating to me.<br/> I connected the limit switch input to a GP i/o input of the Raspberry, what I can't do is define the pin in the SMC_homing fb, what I have to write to ensure that my PIN 4 is active and reads the limit switch?<br/> It might be trivial, but these are my first steps on codesys.</p></div>

<div class="markdown_content"><p>A proposal would be to connect a a GPIO input to do the limit switch if the distance is not to long.</p></div>

<div class="markdown_content"><p>Thanks for the answer, also placed an image of the connections, I can't understand how to use SMC_homing, how can I define the switch input PIN?</p></div>
