Thread: Serial monitor erratic separation issue

    Serial monitor erratic separation issue


    I have a sketch running on a Teensy 3.2 and sending data to the USB port (used in serial mode). I check the data on the Arduino IDE with the serial monitor / serial tracer.

    My data are basically 12-bit ADC measurements from sliders with a bit of filtering. So I do not expect values outside the 0-4095 range.

    Here's the code:

    #include "MeanFilterLib.h"
    int filtered[12];
    int raw[12];
    int inputs[] = {A9, A8, A6, A5, A4, A3, A2, A1, A10, A11, A14, A0};
    #define LED_PIN 6
    MeanFilter<long> meanFilter[13](200);
    void setup() {
    void loop() {
      for (int i = 0; i < 12; i++) {
        raw[i] = analogRead(inputs[i]);
        filtered[i] = meanFilter[i].AddValue((long)(raw[i]));

    However I have much bigger values, as if most separating commas are lost at some point and most values are merged together two by two. I don't understand what causes this issue.

    You're printing two values but only one comma with each loop.

    How stupid I am. Thanks a lot oddson!
