    I think your "problem" is, the Teensy just can't output negative voltages. But that's perfectly normal.
    First - Don't set the multimeter or oscilloscope to "AC" mode. Use "DC".

    Hi jonr,

    My multimeter shows me the correct values for DC.
    The smallest AC measuring range is 2 V. The display then shows 1,178 to 1,182 V (probably RMS).

    My oscillator (AC coupling) shows me...

  6. Teensy 3.2 Strange behavior when measuring AC voltage

  7. Teensy 3.2 ADC setting / analogRead Display range

    Hi everyone

    I use the Teensy 3.2, which as far as I know has 13 bits = 8192 values. What resolution is the ADC set "at the factory"?
    At the moment I can clearly only measure with 10 bits.

    analogRead

    Hello everybody,


    I try to use analogRead to generate a threshold value from an audio signal (with appropriate input circuitry).
    The signal has a frequency of 30 Hz (at about 1.5 Vpp).

    Hi Oddson,

    I think there is a misunderstanding here!


    The voltage divider with only 2 resistors (R1, R2, each 3.3K) was only one example. It is completely clear that 1.65 V is measured

    AnalogIn + voltage divider (Teensy 3.2)

    Hi everyone,

    I am currently working on voltage dividers on Teensy 3.2.
    In order to be able to calculate the R1, I would have to know how much current can flow at the Analog IN pin (I max?)
