    Sorry for that. I will enable the page in the next days again. BTW, I stopped my Project because I recognized that there are some hw limitations in the design and better alternatives are available. ...

    I made some tests in the evening with a quite simple code, and hopefully solved the issue. In the following source code I have placed the line "analogReference(1);" alternatively before or after the...

    In principle (and simplified), the Teensy drives a signal generator (DDS AD9851) with some of the digital outputs to set its frequency (1-60 MHz). In an analog circuit the signal is processed and the...

    As far as I understood, one set the Uref of the DAC with "analogReference(x)" ,where x is "1" for 1.2V and 0 for 3.3V.

    But currently I am completely confused about the interworking between the ADC...

    Thank you - I will try that.


    I try to understand the code in ADC_Module::setReference():

    - When I would like to use the internal 1.2V internal reference, I call "setReference" with the...

    Would it be possible to use the ADC library from Pedvide to solve my problem above? It looks like that a call to adc->setReference() only sets the reference voltage for the ADC but does not influence...
  7. Teensy 3.5 - Using different voltage references for ADC and DAC

    In my application I would like to use the
    - ADC based on a reference voltage of 3.3V
    - DAC based on a reference voltage of 1.2 V

    Using the core library (I guess) I only can select the (internal)...

    [posted] Antenna Analyzer

    This antenna analyzer can be used to find out, at which frequencies a short-wave antenna is matched to the 50 Ohm impdedance of the cable and the transceiver. This behaviour is presented by the so...

    Thanks - yes, fillRect() was what I meant (not drawRect).

    Hi,
    just a short question: is it possible to draw thicker lines on the display. As a workaround I use "tft.drawRect()" instead of "tft.drawLine()", but that might not be the best solution.
    Thanks....
