Hello, I have problems compiling a sketch, ide tells me no such file or directory. the library in question is ACCELSTEPPER. I state that I have it in the third-party libraries menu. I also tried to install it from a zip file, but nothing to do, always the same error. thanks

C:\Users\mimmo\Documents\Arduino\sketch_oct23a\sketch_oct23a.ino:1:11: fatal error:  AccelStepper.h : No such file or directory

I think that means you need to install the library. Open the Library Manager on the left and type AccelStepper in the search box.

# include < AccelStepper.h >

Remove the spaces.

# include <AccelStepper.h>

Thanks for the tip, I followed your suggestion and the file or directory not found error no longer gives me the error. but give me another one.........

any other suggestions?
Thank you

david_2018 · October 27, 2024, 11:16pm

The stray \xxx messages are caused by downloading the code incorrectly, web browser or web site is inserting formatting characters.

Copy the code from your initial post (hover mouse pointer over upper right corner of code box to get copy option), and past it into an empty sketch, that should compile. The forum removes those extraneous characters. Looks like that no longer works.

cattledog · October 28, 2024, 12:25am

Yes I found the same thing. I copied the sketch into Notepad++ and found some strange entries ZWSP in black scattered in the code.

There are way more issues than that, and you are in copy/paste hell and there is a mix of English and Italian which I doubt will work.

There is no setup() but rather

impostazione nulla ( ) 
{

There are also for loops with Italian

per ( int i =  0 ; i < 50 ; i + + ) 
  {

sterretje · October 28, 2024, 5:41am

Hello @saturno59, next time please post text from the output window using code tags; easier to read and easier to copy.

I've fixed your post #7; note that you did it correctly in your opening post.

saturno59 · October 28, 2024, 11:52am

hello and thanks for the reply. I did the procedure you suggested and in fact I found some blackened characters, which I deleted. and I checked the code with IDE, and now I have another error, highlighting lines 23 and 101 which I highlighted between asterisks.... sigh sigh

hi asterisk, sorry, I hope I did it right now.....

oqibidipo · October 28, 2024, 1:58pm

should be

void setup()

should be

for (int i = 0; i < 50; i++)

oqibidipo · October 28, 2024, 2:07pm

should be

     tempX += analogRead ( Analog_X_pin ) ;   
     tempY += analogRead ( Analog_Y_pin ) ;         
     tempR += analogRead ( Analog_R_pin ) ;

saturno59 · October 28, 2024, 4:14pm

compilazione ok, flash ok su arduino uno, grazzzzzieeeeeeee fluente, e grazie anche agli altri........in serata assemblo il progetto e verifico......seguiranno info

Hi, I have assembled the project, for now with only one driver and one stepper. It works perfectly. Next step purchase a better, more sensitive joystick, so you can control better
acceleration. Then the whole project will be mounted on the telescope mount.

@saturno59

Please use the English language in the English section of the forum.

saturno59 · October 28, 2024, 6:49pm

you're right, sorry, I'll take care of it
