Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Only Simtools v1.2 has the fixes.

I have numbers now !

hi RufusDufus,
Do you have any news regarding the problem we have.
Eric told me that he still have the problem.
If i uninstall anr re-install the simtools v 1.2 will make any difference?

Hi spartan, Is your problem exactly the same or just similar?

You must be using the v1.2 beta version - this is the one with the fixes. Note however the beta is not publicly available, please refer to the PM I sent to your forum inbox.

I have not been able to reproduce any issues with v1.2 beta so far.

Hi , I'm trying to connect this to simtools but I can I'm only using one computer is that ok or I need two before I use racingmat arduino code and everything worked ok only wanted to try this one because I feel that the code from racing mat was missing some feeling I didnt feel the acceleration/braking or the gears changing.
with this code I can connect to the smc3 util but even there the pots are very sensitive in center .

Yes this can be used with one computer. The best way is to use it just like any other Arduino code and just connect direct to Simtools. In this case you only need the windows SMCUtils to setup the Arduino parameters then you shut it down and run Simtools. Best getting this to work before trying other modes.

To setup Simtools to connect direct to Arduino SMC3 use the following settings.
SER output, with connected comm port
500000 baud, no parity, 8 data bits, 1 stop bit
10 bit binary output.
Output string: [A<Axis1>][B<Axis2>][C<Axis3>]

(Note you need to include both square and triangle brackets above)

**** warning the pinouts may not be the same as other Arduino code - check first ****

I CONNECT EVERYTHING ALRIGHT USING THE DRAW FROM ROBBIE, BUT I DIDNT KNEW I HAD TO SWITCH OFF SMCUTILS BUT LIKE IS OFF IS WORKING IN SIMTOOLS THE OTHER THING IS THAT THE POTS NOW ARE VERY SENSITIVE IN CENTER THERES ANYWAY TO ADD SOME DEADZONE IN CENTER AND DO I NEED TO SET LIMITS IN SIMTOOLS WHEN START AND OFF LIKE THE RACINGMAT CODE.
SORRY FOR THE CAPITAL LETTERS BUT IS MY MOBILE NOT CHANGING FOR SMALL

You can setup various parameters in the Arduino SMC3 code including a deadzone and axis limits. Use the windows SMC3 utils to do this setup. Once happy everything is automatically saved in the Arduino. Shutdown windows SMC3 utils and run Simtools.

If movement is too sensitive you can fine tune motion using Simtools tuning center.

Thank you very much for the help and for the amazing code now is all working just need to do some fine tuning.
what forces should I put for the likes of F1 2013 , Pcars, race 07 should I put all of them?
once again thank you

Great to hear it is working!

You will probably get more responses to your question about forces if you create your own thread in the DIY forum. I suspect this is very much related to the type of sim and personal preference.

hi thanks for servo sketch robbie i need to change to set up as the i think its the 301 simulator this i have looked at the sketch what should i put for the rear centre servo
to add it to the the left and right
const char kActuatorName[kActuatorCount] = { 'R', 'L' };
const int kPins[kActuatorCount] = {4, 5}; // pins to which the Actuators are attached
const int kActuatorScale[kActuatorCount][2] = { { 0, 179 } , // Right Actuator scaling
{ 179, 0 } // Left side Actuator scaling
}; i have set up all 3 motors today finally got them finished as you can see in the pictures i am using a hospital bed control just for testing what control 4 motors 24 v
i only need to use the 3 of them two at front and one at the back as i will not be using tv using the oculus rift to keep down the weight i have put on a pic for the settings for robbie i need some help so close for testing

just wanted to add got measuring pot value i have been playing with gametrack its a fight golf controller easily works with arduino its spring loaded save breaking pots and it good for liner measurement they are cheep to buy i hope this helps some one

Hi, I think you may have responded to the wrong post... It sounds like you are referring to different code than SMC3?

Just thought I'd ad my thanks for the wiring diagrams on page 1. Thank you very much, this all helps a lot.

Sorry for the late update. Just wanted to say that your code is working perfectly for the traction loss axis on my rebuilt 2DoF platform. It really was easy to set up following your instructions on the first page. The utility program allowed me to test and tune the motor output before I connected it to the platform. This really saved me a headache as my pots are 10 turn with is massive overkill for the reduced gearing that I am using on the winch motor.

Great work and thanks again for taking the time to help us out.

HELLO.

VERY GOOD JOB!! I LOVE IT!
I'm building my 2DFO CODE YOUR SYSTEM.
IN BRIEF ascend PHOTOS ..
REMAINING THIS FINE.

I AM A GENIA, JEJEJE.

I BOUGHT THIS:

60A Motor Driver Dual H-Bridge Drive Module PWM Control for robot car projects

http://www.ebay.es/itm/60A-Dual-Mot...LH_DefaultDomain_0&hash=item3cd159fd0d&_uhb=1


HOW TO CONNECT AND NOT, I HAVE AN IDEA, BUT I PREFER ASK NOT BREAK THE MODULE.

IN1_L ---- ENA - MOT 1
IN2_L ---- ENA-MOT 2
IN3_R ---- ENB - MOT 1
IN4_R ---- ENB - MOT 2
EN_L PWM ---- 1
EN_R ---- PWM2

It is CORRECT?

THANK YOU

I downloaded the SMC3 zip files but I am having problems with the SMC3utils v06 file. When I open the file and click "RUN" I get a message that says it was unable to connect to the com port. (pic#2) I am using Com #4 I went into the ini file and changed the com port from #7 to #4. (pic #4) That did not work, same message Is there something else I need to change to make this work?

Did you install SMC3 via the Arduino IDE? I know this might be a simple question but you never know....
