CONTROLLINO MEGA behaviour

Using Arduino Project Guidance
1

Hi

I'm trying to run a stepper motor using CONTROLLINO MEGA and a stepper driver (DM332T), but I'm not gettin' much progress.

One of the things that calls my attention is that I use pin D8 (for example) of controllino as an output. When I run the code, the light of this pin should blink according to the code. The impressive thing is that pin 8 remains off and pin 6 does what pin 8 should do.

So I tried to use one of the example codes on ARDUINO IDE library (Basics>Blink). I use it to make pin 10 blink, but the pin that blinks when I run the code is pin 8. If I want pin 7 to blink, is the pin 5 that does it. Basically, the pin that I use in my codes does not do what it should. Instead, the pin "2 positions earlier" does it.

Is it normal? I'm getting confused because I'dont know how should I build the circuit (to run the motor) because of this.

Thank You!!

I think you forgot something...

What? It's my first time using ARDUINO and similars,. Could you help me? Thanks

Please post a link to the board that you are using

Meanwhile have a look at the pin out for a mega and make sure you have selected that board from the IDE .

We need the board detail and the sketch putting up between code tabs .

Hello
You may check the CONTROLLINO pining versus Arduino pinning.

Thanks, How can I do that?

Have a look at the diagram and see where D6 connects to the processor ( it’s too blurred on my phone ).
Have a look at the schematic for a Arduino Mega and see where D6 connects - if they are different that’s the issue .

There must be some examples with a library for that device , they may help too as will a good look at the documentation . As it’s not an Arduino product there may well be such differences , such as bringing out more I/O Pins .

Have you downloaded the library for the board

What you observe is normal for this board, the pinout is different. Go to their website, everything you need is there.

Yes I did! But you were right!! The schematic of CONTROLLINO MEGA match' each pin to ARDUINO MEGA, and it happens exactly what I was describing I think:

So I guess that if I want to do something with PIN 7 on CONTROLLINO MEGA, I have to write PIN 9 on ARDUINO IDE, right? Even If I have loaded the library of CONTROLLINO..

Otherwise, I think I have to use the above table, but Im not sure how to interpret it... Any explanation?

There is a board manager and you select that board within the ide ( and not Arduino mega ) I would have thought all the differences would be then be sorted out for you .
I see from the site , there are downloads to install. Have a good read of the instructions , it does include a board manager and controllio should then appear in your boards list and the O/I then line up
.

Yes, this is the firs that I did before running any code. I have selected CONTROLLINO MEGA on tools>board and I have included the controllino library on the top of the code, but still PIN 8 blinks when I want PIN 10 to do it.

Hmmm … dunno then .!!

Might be a question for their tech support.

Run some of their examples and see what that does

In your sketch ( located in this post - please don't crosspost, put all information in one thread ) you use simply numbers to address the pin. You should try with 'D10' instead. In the schematic above '10' relates to 'D8', and '12 to 'D10'. I assume the CONTROLLINO board definitions map 'D10' to the correct pin.

I took a look at 'controllino.h'. There are these defines:

  #define CONTROLLINO_D0 2
  #define CONTROLLINO_D1 3
  #define CONTROLLINO_D2 4
  #define CONTROLLINO_D3 5
  #define CONTROLLINO_D4 6
  #define CONTROLLINO_D5 7
  #define CONTROLLINO_D6 8
  #define CONTROLLINO_D7 9
  #define CONTROLLINO_D8 10
  #define CONTROLLINO_D9 11
  #define CONTROLLINO_D10 12
  #define CONTROLLINO_D11 13

So you need to use CONTROLLINO_D10 as your pin name if you want it to be output on D10.
