Data acquisition



  • Hello,

    I would like to acquire data with my Neuron M103, those of the voltage received at the analog input as well as the voltage sent to the analog output of it. I then looked on the tutorials available on your unipi.technology website to see how it was possible to achieve this. I have read the History tab on the Mervis IDE software (which I use for programming the Neuron). So I followed the tutorials and imported the Neuron's analog input and output into this history. This works fine and once downloaded the History is visible in a .csv file.
    However, I would like to sample below 1 second in order to more accurately observe the change in values ​​on the analog input. I then modified the parameter "Save Period" of the tab "History Log" and put 100ms, which should allow to save 10 values ​​per second in the .csv file. But when I download the History, I always get a single value per second ...
    Do you know if it is possible to sample under a second? And if this is possible, how do we get there?
    If this is not possible with the History part, how can I get what I want?
    Thanks in advance.

    Hello @Mathurin,
    when you deploying the solution, please check the "Cold start" and "Clear Flash Variables".

    Best regards,

  • Hello,

    I just followed what you told me yesterday, but that doesn't change anything. In my .csv file, the values ​​that I save its data every second and not every tenth of a second ...
    For the use that I make of it, it is absolutely necessary that I can obtain more values ​​per second.
