    Wow, what a fast reply! - Thank you

    I am in the UK so the link is much appreciated.
    I think I may have found it on their website.

    My contact was with Nick Roast and at that time the board was still pre-production (mine is very small and round). But its good to see its now really available, thanks for the info !!

    Progress report:

    I have further increased the size of the sampe_buffer, from 64Kb to 96Kb. At 281K samplerate the short burst of noise when writing to the SD comes new gets recorded every 150ms or so.
    Next to this I have connected my preamp to the 3.3v from the Teensy instead of the (probably more noise prone) 5V coming directly from the USB. This does reduce the gain of the preamp clearly but also has had a good effect on the overall backgroundnoise. In the image below you can see the noisespectrum when recording (micgain is 50) in a noisefree (nearly) environment. I used audacity to plot this for a section of around 100ms of a recording (no SDwrite noise).

    For the software side I am still clearing up and commenting more of the code to make it more accessible.

    My mic has not arrived yet however I thought I'd get the sketch installed. I'm struggling to find the uSDFS library, can anyone point me to the right place?

    I seem to have something wrong but I've got to head out now so will check later:
    "uSD.h:40:15: error: conflicting declaration 'typedef short int boolean'"
    looks like it is defined elsewhere as:
    typedef bool boolean;

    I have not experienced that myself but I know others have. This might have to do with the fact that I am running this inside Visual Code with the platformIO IDE.

    while I had other issues with other existing libraries, this one is new to me.
    I would either comment the typedef in uSD.h or proceed it with a #undef boolean line

    dont't forget, editing a library require a change in the settings (either F_CPU or other parameters under tools) to force recomplilation of the libraty

    Thanks, I commented it out and all compiles ok now :-)

    Apologies if I should ask elsewhere but I can't get it to upload - possibly my unfamiliarity with the Teensy:

    Code:

    "File contains data beyond chip size, yikes!" - that doesn't sound right...

    If I press the button on the Teensy, the LED stops flashing, goes dimmer and the Teensy loader verbose info shows:

    I've had a look at the troubleshooting area but this looks different. Any ideas?

    Hi,

    Looks as if your compiler is not set for a teensy 3.6, the 165Kb Hex should fit easily on a 3.6. As I am not using this compiler setup I cannot comment on the other messages. I work using Visual Code with the PlatformIO IDE to debug/compile directly to a teensy.

    regards

    Thanks, I'll investigate further. Weirdly the IDE seems to think things are ok - "Sketch uses 165200 bytes (15%) of program storage space. Maximum is 1048576 bytes.", it's just the Teensy loader that is showing the error.

    EDIT:
    Sorted it - the udev rules had not installed correctly - installed those and rebooted and I can download blink_fast and also DD4WH_Bat_detector_v1_2.ino.hex. Now I need to attach the screen and see if anything appears :-)

    Ok, screen is connected up and it's now displaying something sensible. Initially I just got a white screen but it turns out you have to put an SD card in or it just spins writing out a serial message. I changed the order of the code slightly so that it displays an error on the screen if the SD card is missing.

    Anyway, looks good but frustratingly my MIC has not arrived yet :-(

    I see you are using the original code, I have changed the code quite a bit and I am still working on it. You can find that on my github-page https://github.com/CorBer/teensy_batdetector

    Ah excellent, thank you. I've cloned your repo so I can take a look

    Hello DD4WH, thanks for this amazing progect.
    Im trying to replicate but i m not able to compile your .ino (ff.h is missing)
    where can i find that? maybe teensy new versions have a different name for the SD card libraries?

    cheers

    Hi i noticed you arrange your code differently , there is no .ino?
    Maybe its a noobish question but are you using another IDE or how could i stick your code into arduino IDE?


    thanks in advance

    if you copy the code into, say, "Arduino/teensy_batdetector" where Arduino is your sketch folder, simply create an empty file "teensy_batdetector.ino"
    this keep Arduino happy and allows you regular C/C++ programming (without Arduino interferences)

    those functions are defined (public) in AudioEffectGranular class inside effect_granular.h
    so i think im messing up with the code integration

    Hi

    I am currently on a holiday, be aware that I have build the most recent version of the batdetector with VisualCode as my IDE and inside a platformIO setup and on a Linux system (LM 18.3). Your warnings might be due to differences in the setup as you seem to be on windows10 and probably using the arduino IDE.
    In my setup the locally changed audio-library effect-granular is used during compiling, it seems in your case the compiler still takes the default effect-granular files.

    You can ignore the warnings, they only refer to different language standards.
    The errors, which complain about effect-granular, as CorBee explained means you are using different library.
    So, you have to find I CorBee's GitHub his modified effect-granular library and copy that into your local Arduino library.

Your warnings might be due to differences in the setup as you seem to be on windows10 and probably using the arduino IDE.
    In my setup the locally changed audio-library effect-granular is used during compiling, it seems in your case the compiler still takes the default effect-granular files.

    Hi CorBee, i hope you enjoy your holidays.
    First time i heard about platformIO im going to give it a try.

    Hi

    If you (like me) program on different platforms with different compilers using platformIO is really great. I program on TI MSP430s, arduino, teensy, esp8266 using platformio in visualcode. Full access to libraries across the compilers.

    regards
    Cor

    Thanks @CorBee, I'd not considered PlatformIO before you mentioned it, despite using VCode. I have now installed it and got your code to compile and upload to the Teensy - it lives!
    I've now realised I'm missing a couple of rotary encoders so I can't do much until I get them :-(
    Do you have any you'd recommend? - Would something like this do? - https://uk.farnell.com/alps/ec12e242...1TP_SearchNB_2

    I do use MSP430 for other applications so I'll have to experiment with PlatformIO. I usually use Eclipse for MSP430 so I'll be interesting in seeing how it compares...

    The Alps encoders are probably ok, as long as you both an encoder and pushbutton. Function.

    Platformio works fine using Arduino style programming on Msp430

    Ok, encoders have arrived, I've fitted them and can now control things

    I am struggling to get my head around what is going on though. I can see a spectrum display and that responds to speech and changing the sampling rate works as expected. When I try changing to one of the other display modes, I get no display (I do get the menu and info etc but no data). What am I doing wrong there?

    Also, could someone point me towards a definition of the terms:
    detector_heterodyne
    detector_divider
    detector_Auto_heterodyne
    detector_Auto_TE
    detector_passive
