Can you send me your render.cpp ? giulio @ bela.io

Also, what version of Bela are you running?

    you have a

    return true;

    at the eight line of setup(). This means that all the remainder of the function, where libpd is setup and initialized is not executed. Therefore you are basically running the project without libpd. I guess I should have specified that when describing the operations needed to achieve you result.
    Remove that line and everything should work fine. Leave - however - the return true; line at the very end of setup().

      giuliomoro Never mind, I see the one I need to get rid of, the one I keep is on line 350

        giuliomoro I've removedf the return true; on the 13th line of setup and now when I click run project I get this error:

        alt text

          right, that's because of the duplicated scope.setup() lines. Remove the scope.setup(2, 44100) from the fourth line of setup(). Also, remove these lines from the top of render():

           // Logging to the scope the pulse inputs and the distance
        scope.log(digitalRead(context, n, P8_08), distance/100);

            giuliomoro Nevermind, I had the wrong object name in Pd, getting it printed in the console now 🙂 thanks for all your help - I'll give you a buzz if I need anymore help. Is there a donate function on the Bela website?

              giuliomoro Haha, cheers 🙂 I'm going to have a crack at implementing a second sensor and Pd object for it, thanks for giving me confidence with C++

                giuliomoro Hiya, back again 😛

                I've attached two sensors now, with the second sensor attached to:

                GND: P08_01 Ground
                ECHO: P08_10
                TRIG: P08_09
                VCC: The pin next to (horizontally) P09_07

                I've duplicated the variables at the top of the C++ file:
                alt text

                and made the duplicates and changes to the setup:
                alt text

                and duplicated the render part:
                alt text

                Here is my new Pd patch:
                alt text

                but as you can see, the console is printing the same number for both sensors. 🙁 I get the feeling I've done something wrong with the render part...

                  You also need two separate PulseIn objects.
                  Just now you are initializing the same object twice, with the second call to init() probably overriding the first one, so you currently are only monitoring the second sensor.

                    giuliomoro Got it, thanks, I overlooked that. Now its working but the console is updating every 1 second or so, instead of the constant stream of data like it was before, any way to fix that?

                      giuliomoro Ah, its not actually, its just scrolling up the window and not staying at the bottom of the console window. Interesting..

                        That may be due to the zoom of the browser tab containing your IDE window not being 100%.
