  3. micro-second counter?

    in MIOS programming (C)

    Posted

    i need a count from 0-1ms (to modulate the triggerlength for a TR606 - in order to get some velocity-like reaction from the machine)

    count is not the problem, more the execution of the function

    also to make a RTOS-Task for it - i know very well and use it a lot.... but since now i dont needet anything under 1ms Rate...

     

    when change from (taken from tutorial 006_rtos_tasks) 

    vTaskDelayUntil(&xLastExecutionTime, 1 / portTICK_RATE_MS);

    to 

    vTaskDelayUntil(&xLastExecutionTime, 1 / 10);

    has it effect or is it "fixed with min 1ms" ?

    are there MIOS functions i can use instead which have a better call-rate?

     

    thx 4 info

  4. MIOS Studio "Error Reading Files" Linux Mint 19 64bit

    in MIDIbox Tools & MIOS Studio

    Posted · Edited by Phatline

    ok i thougt maybe there is something with the "browse-button" programming and Linux Mint Mate19? in context with PATH-grammatic (/)

    so i readout the Path of the hex file with: 

    t@t:~/Downloads$ readlink -f project.hex
/home/t/Downloads/project.hex

    i then paste the result directly into the Browser-Field of the MIOS-Stock-Built and Mios_Studio i built on this machine (today-after installing all the librarys)

    and it F***ing Works!!!

    the browser Button, is not in function with Linux Mint Mate 19!
      

    Version Linux Mint 19 Tara 64-bit
Kernel Linux 4.15.0-38-generic x86_64

    i then built a Mios_Studio on this Linux Mint Mate19 Machine,

    but the build give me the same error when loading a hex file: 

    t@t:~/midibox/mios32/trunk/tools/mios_studio/Builds/Linux$ mios_mate19-2
JUCE v2.0.38
JUCE Assertion failure in juce_File.cpp:149

[1]+  Angehalten              mios_mate19-2
t@t:~/midibox/mios32/trunk/tools/mios_studio/Builds/Linux$

    aha.... i then searched again for "juce_File.cpp" and i found it under: /home/t/midibox/mios32/trunk/tools/juce/modules/juce_core/files

    which now exist because i had to unpack the juce files in order to make a BUILT

    so line 149 says: jasserfalse - which i think is a break command in this ELSE if... which has something to do with Absulute Pathes and "/" (((dont know what that mean)))

    -by the way i searched the .hex-file with the "browse-button" since a drag and drop of hex never worked on Linux anyway (in this case it of course also not worked!) 

    jassertfalse;
       else if (! path.startsWithChar (separator))
    {
       #if JUCE_DEBUG || JUCE_LOG_ASSERTIONS
        if (! (path.startsWith ("./") || path.startsWith ("../")))
        {
            /*  When you supply a raw string to the File object constructor, it must be an absolute path.
                If you're trying to parse a string that may be either a relative path or an absolute path,
                you MUST provide a context against which the partial path can be evaluated - you can do
                this by simply using File::getChildFile() instead of the File constructor. E.g. saying
                "File::getCurrentWorkingDirectory().getChildFile (myUnknownPath)" would return an absolute
                path if that's what was supplied, or would evaluate a partial path relative to the CWD.
            */
            jassertfalse;

           #if JUCE_LOG_ASSERTIONS
            Logger::writeToLog ("Illegal absolute path: " + path);
           #endif
        }
       #endif

    when clicking in the mios-studio browser-adress-bar i get this for example: 

    /home/t/Gtk-Message: 17:35:54.994: GtkDialog mapped without a transient parent. This is discouraged.
/home/t/Schreibtisch/project.hex

    the rapid hole getting deeper, and i even dont know "i am in the right hole?"

    i also tried a on my own compiled version of mios studio - and it fries when try to open a hex file 

    t@t:~$ mios_msi
JUCE v2.0.38
JUCE Assertion failure in juce_File.cpp:149

[1]+  Angehalten              mios_msi
t@t:~$

    since i dont found juce_file.cpp in the mios_studio binaries... i only found juce_file.cpp in for example: /home/t/midibox/mios32/trunk/apps/synthesizers/midibox_sid_v3/juce/JuceLibraryCode/modules/juce_core/files

    but there is no Line 149 (it is but it is a comment only...)

     

    have no idea, whats happening, maybe there are more i386-librarys that are what needet - but to bad they make no error - so i cant find out which one left, or is there a other problem

    i have a 64bit Linux Mint Mate 19

     

    mios_studio is not running:

    meen when i double click, nothing happens,

    when i open it with Command-Line i get error messages like: "Error while loading shared libraries: libfreetype.so.6" and others... this things are installed on my system, when i then manually install the i386 library of it - i get it running.

    for example: 

    sudo apt-get install libx11-6:i386

sudo apt install libxext6:i386

sudo apt install libfreetype6:i386

sudo apt-get install libasound2-plugins:i386

    after that mios_studio is running.

    i could get 500 Midi Socket for 127€ excl Import taxe from china --- which give about 0,25-0,5€ for a Socket ---

     

    anyone interested to take 100? (i am in austria)

    - dont think i want to hold more then 100 here in my workplace - so 400 would be aviable.

     

    best mike.

    in UI-Essentual-Kit - the last element of the boom is used the maker number: (makes not a different, but it confuzed me... came to a part which not exist, but as i can see evertything is in stock! sorry.)

    4816P-T02-103LF|1   (thats maker nr.)

    652-4816P-T2LF-10K|1 (thats mouser nr.)

     

    782-6N138 CORE-essentual-Kit         1800 in stock - but stopped production    -      can i take  6n136 instead?  or others (will not that go away that fast,but since on lcsc they have for example 136 but not 138...for example)

    i have finished  going thru the BOOM (making a excel for what i order from lcsc and what from mouser)... there are a couple mouser not in stock with weeks of lead time... (just a note, doesnt matter for me - same for lcsc ... until all is aviable, there will be some other not in stock, while other get in stock again...i understand)

    quest: the "517-929836-01-36-RK" (2x72pin header) is it really needet@once? > or is it to cut down to get smaller pin headers? --- i ask because its 3,4€ on a other side i could get e.g. 3x40 for 0,3€ each...

    Posted · Edited by Phatline

    I am sourceing cheap alternatives to mouser, for my projects, and for you dipcorei want to try https://lcsc.com for some of the parts. (some parts i already put in your dipcore wiki boom)

     

    some questions:

    RESISTOR:

    do they need to be 1/4W or are there some where 1/10W is enough?

     

    CRYSTAL:

    i dont know what Quarz you take... but when look at the footprint then it looks like it can only be "Reflowed" ? since the solder points are under the crystal? most of the Crystals i found have it under the Body...

    for example: 8MHZ 12pf

    how we solder them?

    C12-C13:20pf - had to be changed when using a other crystal.... so for the example above i would replace it with 12pf (or is there more i  have to think of?)

  24. CC-Looper (4ch controlchange looper)

    in MIDIbox User Projects

    Posted

    4Midichannels @ each 512Steps X 32th X 128 CCs

    of course only a few of the 128CC should be used @ once - 4x128xCCs @ 32th is Midi Data MESS and µC Death :decayed:

    maybe only 256Steps, will depend on RAM.... RealWorld will tell

    each TRACK has a shared Track length for all its 128 CCs,

    The Whole Track can be copied, or a single CC.

    There is no EDIT, you can erase a CC or Track and make it new/override

    CC-Looper need a Synth with LEDRINGs -otherwise you have no Feedback and Overview.

    --- for Synths without LEDRINGS i take MSQ-CC-LRE http://wiki.midibox.org/doku.php?id=msq-cc-lre - it has 8x32CCs and can automate them, and Save and Dump/Recall-them -  CC-Maping is Hardcode.
