Tutorial SMC3 Arduino 3DOF Motor Driver and Windows Utilities

Which error? Please can you attach the screenshots of you steps before uploading the code? Do you have selected the active COM port where the Ard is connected before uploading?

Please use for testing purpose SMC code 0.63 http://www.xsimulator.net/community/attachments/smc3-v0-63-zip.11398/ and the newest Arduino Software. @RufusDufus any suggestions from your side?

hi Rufus,

I would like to try your code, but is compatible with my motor controller card? (Arduino + pololu VNH5019)

Here is the link for the card:
http://www.pololu.com/product/2507

is what I must change the code? (pine)

Here is the link to my post:

What is the difference with the code I use At the present moment, that of Racing Mat?

thank you for your answer

you need to define either ENABLE POT SCALING or liner or non liner pot scaling in your arduino IDE try that and see if it helps
Terry

Tank you for your answer, i will look tonight

Hi, I am currently on holidays and can't see the images too well.

If you are still getting compiler errors then I would suspect there is something wrong with your installation of the Arduino IDE. Make sure you are using the latest version.

Try installing the basic Arduino Flash LED code on the arduino site, make sure you don't have any problems with that first.

If the error is that it can't connect with the arduino to download code then make sure no other code is running and connected to the arduino. Ie shutdown Simtools and windows smc3 utils before trying to program the arduino.

It looks like you have the wrong interface settings in Simtools, but if you can't program the arduino you don't have to worry about that yet. The details you need are in the first post.

I will have a closer look at screenshots in a week when back from holidays.

I will have a closer look when I'm back from holidays.

RacingMats code is good code that has been used by many. If you have that working stick with it until you have everything else working (best only to change one thing at a time). The SMC3 code gives you a bit more control over the motor drive using a PID control loop. It may give you some finer detail in your motion, but not everyone notices a difference.

While you can enable the POT Scaling as Terry indicated, don't do this unless you actually have a POT connected!

thanks rufufus, good holidays

When I open the utils SMC3 appears this?
What should be happening?

Hey rufusdufus:, How can I make my 10 turn/10K pot work with SMC3? no matter what I do I cannot get any signal to my motor to make it run. I am using the tail rotor gear (like histoker) on my gear cluster winch motor set-up. The pot is (BOURNS 3590S) I have it connected according to the manufacture specs. ( A three turn pot works ok?)

A Happy New Year to all and God bless you greatly!

make sure your potentiometer is in middle position(2.5V). this is one feature of this code if it goes out of limits it disables the motor until you get it back into limit zone, otherwise smc3 will keep it disabled

I cannot see the green (potentiometer) line. Are they connected and correctly wired? BTW the screenshots are too small and less quality. PS: if the hint of @insanegr should not be successful.

Caro colega, se precisar de ajudar estarei a disposição

Trying to do some test to with my arduino and SMC3, this returning me the following bug compilation:


SMC3.ino: In function 'setPwmFrequency void (int, int)':
SMC3: 259: error: 'TCCR2B' was not declared in this scope
SMC3.ino: In function 'void InitialisePWMTimer2 (unsigned int)':
SMC3: 296: error: 'TCCR2B' was not declared in this scope

Some error code or hardware

grateful

It looks like the Arduino IDE/compiler is not installed correctly. Have you been able to compile and load other arduino code?

Make sure you are using the latest Arduino IDE from their site.

Good morning presado RufusDufus, yes did this test and the cause more logic can be the difference that my Arduino board is the Leonardo and ta and a mega 1280.

hello RufusDufus
first of all thank you for the work you have developed further and helps the community .
I have nothing idea of writing arduino code , and I would like to consult you .
is that use x -sim and simtools , with ibt -2 and arduino one .
connections are different for each firmware , which increasingly have to change all connections.
would be very difficult to modify the output to coincidie with both firm and not have to go changing everything every time ?
considering that I have no idea of modifying the code , I see that some fellow indicad you how to change the analog outputs for the potentiometers .
serious as simple as that ? modify the values that indicate the number of each output ?
or is it more complicated for in total newbie like me?
to see if you get me out of my doubt and pulled something clear before spoiling the code and getting nothing .
greetings , manuel

Hi @Petar2, could you be a bit more specific as to what you are trying to match. Do you have a wiring diagram or link to the firmware that you currently use.

The arduino has limitations so only some things can be changed.

Ok
ARDUINO----------------------------IBT-2

Motor 1
Pin 2-------------------------------------- Pin 1
Pin 3-------------------------------------- Pin 2
Pin 10-------------------------------- Pin 3 y 4


Motor 2
Pin 4------------------------------------ Pin 1
Pin 5------------------------------------ Pin 2
Pin 9-------------------------------- pin 3 y 4

This is the connection that I have with xsim , and I wonder if you can change this so that it is equal on both firmwares.
so should only load the appropriate code to each software ( simtools or x -sim )
it could change your firmware connections to be the same as that used in X - sim?


Here I show as indicated in the code using arduino pins to the bridge -H
respect

Pin out of arduino for H-Bridge

Pin 10 - PWM1 - Speed for Motor 1.
Pin 9 - PWM2 - Speed for Motor 2.
Pin 2 - INA1 - motor 1 turn
Pin 3 - INB1 - motor 1 turn
Pin 4 - INB1 - motor 2 turn
Pin 5 - INB2 - motor 2 turn

Analog Pins

Pin A0 - input of feedback positioning from motor 1
Pin A1 - input of feedback positioning from motor 2
