    • FBD function error

      Hi, when I create function and create some inputs and outputs it gives me an error:

      Error MainProgram testFunction 0 1 there is not declared any retval output for function 'thermometer'. FBD functions have to have retval explicitly declared

      Error cannot find type unresolved

      I don't know what to do. How to build it. There are no other options what I can setup.

      Other issue is when I delete something from this function it is ok, but when I delete other variable I have this error:

      Value cannot be null.
      Parameter name:source.

    • RE: UniPian Neuron OS on UniPi 1.1

      Ok. When you write it like that it makes sence :). I have readed UniPi 1st generation -> This is the same image as for Neurons -> Click -> Choosed image only with Evok. Opensource images was not familiar for me as I was looking for prepared image. Maybe try to make it more obvious and place guide from git hub on the same page, to make it consistent. Anyway thank you for your reply.
