Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

This is very interesting. Would you be willing to share the update code, please?

it wont allow me to upload the file. this is how the code looks with the modification
open your code editor and find the lines for deadzone1 and paste in between to look like this

const int FeedbackPin3 = A2; // Motor 3 feedback pin
const int PotInputPin = A5; // User adjustable POT used to scale the motion (if enabled)

//Pot Filter added by J Latka
int PotData = 0;
int filteredValue = 0; // Initialize filtered value
float alpha = 0.05; // Filter coefficient (0 < alpha < 1)
//Pot Filter added by J Latka
int DeadZone1 = 0; // feedback deadzone
int DeadZone2 = 0; // feedback deadzone
int DeadZone3 = 0; // feedback deadzone

the lines that are between //Pot Filter added by J Latka are the code values

i am no code expert and would like to see some one who actually knows what they are doing implement this filter into the code properly
And to correct my self I used a 10nF cap
Must mention the cap made huge difference but needed some help,of the filter
The url link I posted explains the best

Awesome. But I believe you missed a few line of code, for the 'Feedback1' and 'Feedback2'
Perhaps, you can copy paste the whole code instead?

That part of the code remains the same and in altered
I put that on the post for a reference as to where the additional code is located and inserted
Below is the only additional lines added.
//Pot Filter added by J Latka
int PotData = 0;
int filteredValue = 0; // Initialize filtered value
float alpha = 0.05; // Filter coefficient (0 < alpha < 1)
//Pot Filter added by J Latka

In my above posted comment the lines above and below this is for reference to where I inserted the filter code

i apologize. there was some parts missing and i realized i needed to zip the sketch in order to upload it.
i have attached a copy of the smc code with the filter code in place for those who want to use it
sorry i havent used forums in over a decade

Wow that’s awesome thanks

Hello all, maybe someone can help me please? I am in the process of building 6DOF flight simulator and have already set up a lot using 2 x Arduino Uno R3 and SimTools latest version. I managed to connect 3 motors to each Arduino and can control the first 3 motors by e.g. Microsoft Flight Simulator 2024. The other 3 motors i want connect on the 2nd arduino. My questions are:
1) Can i connect both Arduino's via a small separate usb-hub and
2) How do i adress them in SimTools (I can only select one com port at a time).
Appreciate your help and advices very much! Kind regards, Piet

#1 Yes, use USB hub
# Go to Interface Setup, and set the 2nd arduino board in the Interface2.

Thank you! Just ordered a small usb hub. Kind regards, Piet

Hello "prophet", following your advises i have connect the first arduino on com3 and the second arduino on com 4 now (both via a small hub). Arduino 1 on interface 1 and arduino 2 on interface 2.
How do i assign the 6 axis in SimTools? Thanks for advice!

I am new on SimTools 3. I read the manual and this is what I got from the reading





The rest still default, as I am still learning...

Thank you! its exactly the layout of this picture that i have build (not finished yet)

I was actually confused when I read the manual, here is the screenshot of page 95.



I am expecting tipical axis and dof assignment just like you said, at least that what I read a lot on the Simtools V2.

So for the V3 should I do the 'split vertically' like on the V2?

Noorbest,
My build is 6 DOF stewart with Rotating arm.
So I am on 'Generic 3D Rotating' plugin.

Here is my Simtools v3, and it is a live and make motion that makes sense. But I am curious of your comment above. Now I wonder if my axis assignment is not optimal.

How should I set my Axis assignment? would you mind shedding some light for me please? I hope you can show me an example of the axis assignment I can try and then adjust, more like learning by doing.

I suppose you mean Axis 1a and 6a should be assigned for Pitch, Surge, Roll, and Heave.
But then I'm confused with the "Roll total" on the bottom of the Axis 1a and "Surge total" on the Axis 6a.
