  1. i am offically a artist. i pay social insurance for that. my time is free for midibox making music for contest cd website or gig. have a girlfriend spending lot of time in love. cooking and houshold on my own... and midibox coding planing building consume the rest of it. since i need the devices for a gig end of february i dont have time for tutorials... but when i have some spare time i would make some video doku-to see what to have done BUT not a detailt tutorial for that it is to much information. but i think in german and for a mios based uset project so it would help only a small group anyway. so i have to rethink it i also dont have the best cam equipment nor mony for that..

    maybe this and others is a reason that there are no video tuts outthere ,;)

  2. This code: (app.c download@ http://wiki.midibox.org/lib/exe/fetch.php?media=phatline:tm_v3.zip)

    xTaskCreate(TASK_SEQ, (signed portCHAR *)"SEQ", configMINIMAL_STACK_SIZE, NULL, PRIORITY_TASK_SEQ, NULL);}   // install sequencer task

    do i have to fear?

  3. THX! without that i would have been lost! :cheers:

    worked at the first moment!

     

    i had enough to close and re-open the Mios-Studio every time when uploading new code... specially while programming over weeks daily :pout: deep into code...(and that rescan joke? not funny)

    my cores bootloader is setup ed, to show up as "MIOS32" (when not in bootload mode), so i hardcodet that in mios-studio to be set when press "Rescan mididevices", working under linux mint kernel 4.4.0-98

    no more closing MidiStudio, or have to close multiple-open-instances because of codeing and trying and uploading, then everytime the resize of the window, search and open hexfile and so on. Of course that is hardcodet, but in my case it is good this way, now i know how to compile anyway - thx

    open: svn/mios32/trunk/tools/mios_studio/src/gui/MiosStudio.cpp

    edit: i deleted all from"case rescanDevices" to "break;" and wrote this instead: (the line is about 955 or so)

     case rescanDevices:
            closeMidiPorts();
            initialMidiScanCounter = 1;
     
            getMidiInput();
            getMidiOutput();
            setMidiInput("MIOS32");
            setMidiOutput("MIOS32");
            break;
    

    dont really know exact what is going on there, but for me its working, and thats enough.

    also some colorchanging by searching the gui/....cpp filesvia

    g.fillAll(Colours::black);

    but the background of the main-fields are still white... to bad...

  4. after initialize:

     void APP_Init(void){
      int pin;   for(pin=0; pin<16; ++pin){     MIOS32_BOARD_J10_PinInit(pin, MIOS32_BOARD_PIN_MODE_INPUT_PU);}   }

    getting pin 0-7 is workin ok, but 8-15 give me no output:

    void APP_SRIO_ServicePrepare(void)  {
                // get GPIO-Pins
                u8 x = 0;
                for(x=0; x<16; x++) {
                     
                if(MIOS32_BOARD_J10_PinGet(x) != flag.j10PinState[x]) {
                     
                    MIOS32_MIDI_SendDebugMessage("pin: %d value: %d", x, MIOS32_BOARD_J10_PinGet(x));
                    flag.j10PinState[x] = MIOS32_BOARD_J10_PinGet(x);
                  } }

     

    why?

  5. Hi,

    i want to modify the blm_scalar app a bit

    http://svnmios.midiboxorg/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fblm_scalar%2FREADME.txt

    i want to use it in standalone and via midi/sysex...

    so my question: how to call the BLM internally? when i want to display a "array[16][16]=0 or 1 or 2;"

    i know i can call it like below

    but is there a more direct way to use it?

    thx. mike

  6. hm i get a error:

    app.c:1094:13: warning: implicit declaration of function 'wmemset' [-Wimplicit-function-declaration]
    if(edit & (1<<0))wmemset(loop[track].PB, (u32)((8192<<16) + 8192), (sizeof (loop[track].PB))/4); // reset Pitch Bend

     

    when i then add:

    #include <wchar.h>    to app.c

    then error:

    Quote

    app.c:1169:13: warning: passing argument 1 of 'wmemset' from incompatible pointer type [enabled by default]

    should i change this:

     typedef struct storage {  
            u16  PB [512];    
             u8  SEQ[512] [8];                                    
             u8  MSQ[512];      
    
            char  leader:1;   
            char  virgin:1;      
             u8   length;   
             u8   decay;        
             u8   rythm;    
            u16   bpm;   
    } store_t;

    to this:

     typedef struct storage {  
        wchar_t PB  PB [512];    
             u8  SEQ[512] [8];                                    
             u8  MSQ[512];      
    
            char  leader:1;   
            char  virgin:1;      
             u8   length;   
             u8   decay;        
             u8   rythm;    
            u16   bpm;   
    } store_t;

    hm what size has this wchar_t?

  7. if(edit & 0x0f)memcpy(&loop_copy, &loop[track], sizeof loop_copy);   

    clever i like that :happy:


    but i planned it more like:  check which things have to copyied, so i can copy PB+NOTES, but not CC+Loop-Information, (for default)

    if i get it right: in your thought i can always copy only one thing: PB, All, Notes or Loop-Info

    but i can still use memcpy with for example:

    if( (edit[0]==1) && (edit[1]==1) && (edit[1]==1) && (edit[1]==1) ) memcpy(&loop_copy, &loop[track], sizeof loop_copy);   

     

    THX for your help guys!

    for the rest i will take me time on 23.12... today we make fire in the snow, and celebrate the 21.12 to restart the sun-circle :cheers: happy new sun year, skol!

  8. :blush: aja        a < 8        of course, thx!

     

    Edit: read/write on SD-Card is working fine!

            MUTEX_SDCARD_TAKE;
                    //Write to File
                    sprintf(file_path, "msp/%d-%d.msp", track, clip);             
                    FILE_WriteOpen	( file_path,          16 );   
                    FILE_WriteBuffer( (u8  *)&file_type,   4 );                                                    
                    FILE_WriteBuffer( (u8  *)&loop[track], sizeof(store_t) );

                            loop[track].virgin = tact_info_copy[1];
                            loop[track].length = tact_info_copy[2];
                            loop[track].decay  = tact_info_copy[3];
                            loop[track].rythm  = tact_info_copy[4];  
                            loop[track].bpm    = tact_info_copy[5]; }    
                      break;
                 
    }
    }

    also the code above is working ifne ;)

  9. ok understand, i let the the file describtion in....

    oje...

    there is something wrong with the code,

    http://wiki.midibox.org/lib/exe/fetch.php?media=phatline:seq-melody-footboard-beta.zip

     

    when i make arrays with 8x512, or arrays with 8x1024, the Files on SD-Card is always 5,6kb size, also on 1024 i got hardfaults when copy those structs into arrays (copy paste clear clips), by 512 no hardfault

     typedef struct storage { 
            u16  PB [512];      
             u8  SEQ[512] [8];                                    
             u8  MSQ[512]; 
    
            char  leader;       
            char  virgin;          
             u8   length;       
             u8   decay;        
             u8   rythm;        
            u16   bpm;   
    } store_t;
    
    no difference in SD-File-Size!
    
     typedef struct storage {   
            u16  PB [1024];  
             u8  SEQ[1024] [8];                                 
             u8  MSQ[1024];      
       
            char  leader;      
            char  virgin;         
             u8   length;   
             u8   decay;       
             u8   rythm;   
            u16   bpm;   
    } store_t;

     

    also i initialize all Arrays, but actual most of them (all except the first member loop[0] in the program are 0-out

    void APP_Init(void){
    //initalize 8 Clips with standart values
        u8 a = 0;
        for ( a=0; a>8; a++ ) { 
            loop[a].leader =  0;   
            loop[a].virgin =  1;
            loop[a].length =  1;
            loop[a].decay =  60; 
            loop[a].rythm =   4;
            loop[a].bpm   = 120;
            
            //initiate Pitchbend
            u16 b; for(b=0; b<512; b++)   { loop[a].PB[b] = 8192; }
            };
    
            
        //Initiate Pitchbend - copy paste buffer
        u16 b; for(b=0; b<512; b++)   { PB_copy[b] = 8192; }
    }

     

    the 1024 thing i think is clear, it takes to long to calculate all the data, i would need something like a xtask... but i dont figured out how to make out of a

    Quote

    static void Edit_Clip(u8 track, u16 clip, u16 job);     a    static void Edit_Clip       (void *pvParameters);

    i know:

    Quote

        xTaskCreate(Edit_Clip,  (signed portCHAR *)"Edit_Clip", 256,  NULL, PRIORITY_Counter, NULL); 

    i use such things for counters in ms tact (decay-counters, blink blink...), but not for a function that gets called, work something out, and done...

    for example:

    static void Decay(void *pvParameters){  //Send Note OFFs after a while
       portTickType xLastExecutionTime;
       xLastExecutionTime = xTaskGetTickCount();       // Initialise the xLastExecutionTime variable on task entry
      while( 1 ) {
        vTaskDelayUntil(&xLastExecutionTime, 1 / portTICK_RATE_MS);
        
        for(DcyNteCount = 1;  DcyNteCount < 128; DcyNteCount++) {
                            for(DcyTrkCount = 0; DcyTrkCount < 8;   DcyTrkCount++) {
                                
                                       if   (MeloDecayTIMER[DcyTrkCount][DcyNteCount] != 0) {
                                             MeloDecayTIMER[DcyTrkCount][DcyNteCount]   --;
                                             
                                          if (MeloDecayTIMER[DcyTrkCount][DcyNteCount] == 0) {
                                               MIOS32_MIDI_SendNoteOff(MelPortOut, MeloOutCh[DcyTrkCount], DcyNteCount, 0);  
                                               MIOS32_MIDI_SendNoteOn (MelPortOut, MeloOutCh[DcyTrkCount], DcyNteCount, 0);}}  
                                        }}
    }//End While
    }//End TICK 0 >>> 1ms Task...
