    OK,
    let us do it the following way: you get latest uSDFS from my github and batdetector from CorBee's github
    move uSDFS into your local Arduino library (removing the "-master" from the file)
    compile the batrecorder and post the whole compilation log
    we will work from there.

    Hi Seriesman, I already expected a detailed report of the last few nights...

    For recording you have to set the function of the left pushbutton to record.

    Turn the left encoder until you see ButtonL
    Press the encoder (ButtonL and "DISPLAY" will change to white color)
    Turn the encoder to select RECORD
    Than press the encoder again.

    In the lower left coder you should see REC OFF

    Press the left pushbutton to start recording
    press the left pushbutton again to stop recodring

    Compiling finally worked,

    It does display some warnings but no errors.

    I went back to Arduino 1.8.7 Teensyduino can be 1.44 or 1.46

    I still keep running into time errors so I used my TimeAlt escape to get things compiling.


    I have all libraries that I use and are not exactly standard in C:\Users\..username..\Documents\Arduino\libraries

    I have the feeling Arduino 1.8.9 does not want to work with this code on my Windows10 x64 and Windows7 x86 machines.

    Hi Cor, I'm just glad to be able to help.

    The files that I got compiling under windows in Arduino 1.8.7 are saved here just in case anyone needs them.

    Have you been playing with the playback function? I know you were trying to put that under the left button function. The old way was still working but I don't see it anymore now that I uploaded the latest code.

    Hi,

    No change (at least not intentional) for the playback. It still is part of the main menu structure (position in the menu is after Sample Rate)

    It seems I have some memoycard issues, files are not recognized and recording starts at B1 but I have files op to B55.

    I will have to try again tomorrow. It looks like the 0.82 version works fine.

    0.84 and 0.86 hex file hangs.

    Better have some sleep first.

    I thought I might have run over a maf files number but after deleting files I was not able to record or play back any files.
    The 0.82 version seems to work fine but I did expect the left button function in that one.

    Somewhere I am messing up files I think.
    The precompiled 0.84 and 0.86 do not seem to want to function in my test unit. Selecting any recording pr playback function makes it hang or it hans already after booting.

    Am I the only one experiencing this?

    I don't want to try and upload to my completed unit since i don't want to mess it up before we know the solution. (if we do seem to need any solution)

    HI all,

    It is always possible to download an older version of the code, to do this you need to go to https://github.com/CorBer/teensy_bat...aster/main.cpp
    This will show all moments in time that files were changed/added. If you click on the rightmost <> button on given commit (date) you will see how the repository was looking at that date.

    As I am not experiencing any issues I will wait till its clear what is going on from the tests

    regards
    Cor

    I just compiled the 0.82 version again, it seems I might have posted a wrong 0.82 version earlier.

    This is the real 0.82 hex version.

    I confirm the good result with Pe1pwf work: Windows, Arduino 1.8.7, Teensyduino 1.46
    codes and libraries here:
    https://drive.google.com/file/d/11Bg...1kpG-siBx/view
    I copie Librarie ( except audio) in my arduino lib ; I use the same directory with theses files: OK it compiles.

    I was able to program my hardware, to record some file on SD. Some times I can also read it on teensey.

    I try again under linux, and arduino 1.8.9 : Need to add #define BUILTIN_SD : it compiles but the hex file is to big after compilation !

    Many Thanks!

    Hi Remis,

    Thanks for the info, so you managed to compile v086 using the uSDFS-master library of the 3rd of june 2019. Its important to mention that too, nice to see that testing different arduino versions also can create problems. So version 1.8.7 works as planned and 1.8.9 does not. I know edwin is also testing things, when we get a clear picture I will mention that in the description of the github page

    Thanks for testing !

    Hi Lovely warm evening. Constant Long Eared bat activity. v0.86 recorded 6 sessions of about 2-3 minutes each on SanDisk 2Gb microsd which played back on PC via Audacity 2.3.2. Spectrogram on Audacity was good enough to identify a pipistrelle in the background that was masked by the very loud long eared bat calls. Brilliant. So grateful. This is a marvellous tool. Thank you all of you.

    Schematic supply chek and decoupling

    HEllo
    Many thanks to Edwin for this document and associated work:
    https://drive.google.com/file/d/1Uu2...JJSGXqBRW/view
    I start from this schematic page 8. I check the power supply and decoupling effect

    At the input I add low drop voltage regulator (BD750L5 Rohm) to provide 5V in any case from a battery. Lowest battery voltage at his input :5.3V. With 5V R7 seem to be high in some case: must be confirmed. Go to 8 or 5 ohms : the worst case for teensy is done by one board regulator : http://www.ti.com/product/LP38691
    low dropout voltage (250 mV at 500-mA load current) . Thus you need to be higher that 3.5V in any case. See also voltage drop for LTC1700-3302E:350mV worst case, thus 3.6V min at 3.3V regulator input.

    I Add 220µF small tantalum directly on Audio board 3.3-GND holes. I see noise changing from 50mVpp to few mVpp.

    The TFT is also one of the major noise contributor : I add SMD capacitor ( 470nF , 1µF ) soldered on the TFT pin. Same think on bottom side 3.3V and GND under teensy and audio board.
    If you don’t have oscilloscope you can use the on board spectrum analyseur to check the improvement : without mic connected , with same gain configuration.

    amplifier input check

    Hello
    I check also the NPN amplifier with BC847C. Less gain to begin, and not saturate. I performed simulation and measurements wich are compliants. I suppose a typical 50mVpp input signal to start the analysis. I don’t have microphone at this time, except ultrasonic transducter.We can use theses results to improve gain. After some real test. The codec input use 1.8V for voltage reference. difficult to saturate, but easy to clamp.
    Any way I suggest to check the collector voltage value without mic at the input. See also attached simulation file to help
    measurements with osciloscope: BC847c SMD ; R2=39k ; rb1=135k ; R3=Rc=2.13k adjusted
    direct connection to 100nF input condensator to codec

    test:
    under 300mVpp, from 10Khz to 100Khz I measure 2320 ohms for codec input impedance
    At 40khz : in 50mvpp and out 300mvppout ; G= 20log(6)=15dB

    simulation : 360mVpp out.
    Vc=1.6Vdc continu measured ; simulation : 1.9V

    simulation done with LTCspice.

    I build a second receiver. Measured confirmed:
    Vout=390mVpp
    Vdc adjusted to 1.6Vdc
    Rc measured:2100 ohms

    Hi!

    I am new here at the forum.
    I have build a Teensy Bat Detector with the help of a PCB from pe1pwf.
    Must seems to work OK but I can't get turning of encoders left-right to work, nothing happens, I have tested with hex files 0.82, 0.84 an 0.86.
    I push right encoder and Gain changes from yellow to white but nothing happens then I turn left or right.
    All four pushbuttons are working OK.
    When I load a pushbutton example program from Arduino IDE the turns are working.
    How can I get turning of encoders to work?

    Regards Bengt (Öckerö, Sweden)

    Hi,

    I suggest trying to start a check of the hardware, are the lines of the encoders connected to the teensy ? You can read from the code which line of the encoder should be directly connected to which pin on the teensy. If all that seems to be OK the question is if turning the encoders changes the state of the lines. All this can be checked using a multimeter and no power on the teensy.

    regards

    Some encoders have incompatible pinouts (pins swapped) - maybe this is the case here.

    Thats indeed special, if you try to use the encoder library to do the same does it still work ?
    THis is the library https://www.pjrc.com/teensy/td_libs_Encoder.html

    I have tried this code, not working so good, OK after I added debounce capacitors, but not working in Teensy Bat Detector, used 3,3nF, I will do some more test if I can find some more capacitors with lower values.

    Code:
    /* Encoder Library - TwoKnobs Example
     * http://www.pjrc.com/teensy/td_libs_Encoder.html
     *
     * This example code is in the public domain.
     */
    
    #include <Encoder.h>
    
    // Change these pin numbers to the pins connected to your encoder.
    //   Best Performance: both pins have interrupt capability
    //   Good Performance: only the first pin has interrupt capability
    //   Low Performance:  neither pin has interrupt capability
    Encoder knobLeft(30, 31);
    Encoder knobRight(34, 35);
    //   avoid using pins with LEDs attached
    
    void setup() {
      Serial.begin(9600);
      Serial.println("TwoKnobs Encoder Test:");
    }
    
    long positionLeft  = -999;
    long positionRight = -999;
    
    void loop() {
      long newLeft, newRight;
      newLeft = knobLeft.read();
      newRight = knobRight.read();
      if (newLeft != positionLeft || newRight != positionRight) {
        Serial.print("Left = ");
        Serial.print(newLeft);
        Serial.print(", Right = ");
        Serial.print(newRight);
        Serial.println();
        positionLeft = newLeft;
        positionRight = newRight;
      }
      // if a character is sent from the serial monitor,
      // reset both back to zero.
      if (Serial.available()) {
        Serial.read();
        Serial.println("Reset both knobs to zero");
        knobLeft.write(0);
        knobRight.write(0);
      }
    }

    I think I have wrong type of encoder, shall get new ones and do a new test, thanks for help.

    Be aware that the code in the bat-detector also uses
    Code:
    //try to avoid interrupts as they can (possibly ?) interfere during recording
    #define ENCODER_DO_NOT_USE_INTERRUPTS
