  3. MB808 Seq accent output

    in MIDIbox SEQ

    Posted

    Ok... this one is new to me, at least it isn't officially supported.

    However, you can use any track to generate accent pulses.

    E.g. you could use Track 15 (by default assigned to "Ext3") for this purpose, just specify the right SR and pin number.

     

    Best Regards, Thorsten.

    This is strange! I would like to analyze your track in order to find out, if there are unexpected dependencies.

     

    Could you please use the "track" command in the MIOS Terminal (above the virtual keyboard in MIOS Studio) to dump out the track information, and paste it into this posting?

     

    E.g. assumed your drums are on the first track, enter "track 1", and you will get something like this:

    Did you activate the "fastboot" option in the bootloader?

    It would be interesting, if it works better if you toggle this setting.

     

    It would also be interesting if you've buffered the OLED supply inputs with 100nF caps. See also this posting:

  13. Mackie Control + Extension with Midibox NG

    Isn't it possible to "play" around with the current drawn by them? (-> if i touch the MF it means it needs more current to drive the fader).

    It results in stopping the fader.

     

    It looks as the MF V3 tool has a quite a lot of options allready implemented, which (i think) have to take the current drawn by motorfader, into account..

    I am sure that i am not the first one, thinking about that in this way ;-)

     

    Something like this is already part of the firmware (motor will stop if the fader doesn't move into the intended direction, e.g. because you manually move it into another direction).

     

    But this is actually not the only feature of a "real" touch sensor.

     

    E.g. a touch sensor ensures, that no fader event will be sent as long as you don't touch the fader.

    Accordingly, the fader can be initialized for a much higher resolution without the risk for sporadically jittering values, because values are only sent when you actually touch & move the fader.

     

    Another purpose of a touch sensor is to activate the automation in a DAW without moving it.

    There is no way to determine this with the current drawn, because at this moment the DAW won't send move commands.

     

    Best Regards, Thorsten.

  14. STM32F4 Discovery

    in Design Concepts

    Posted

    The official MIOS32 toolchain is based on gcc-arm-embedded and newlib-nano now.

     

    Prebuilt binaries for Win32/MacOS/Linux can be downloaded from: https://launchpad.net/gcc-arm-embedded

    (and from http://www.midibox.org/mios32_toolchain)

     

    The build will probably fail with other toolchains if they don't support newlib-nano due to this new flag in $MIOS32_PATH/include/makefile/common.mk

    # for https://launchpad.net/gcc-arm-embedded: enable newlib-nano for better performance
# not compatible with other toolchains (users have to switch to new version, or disable the line below)
LDFLAGS += --specs=nano.specs 

    therefore an update to the new toolchain is required.

    And it's worth the change, because I measured performance improvements in many MIOS32 applications! :smile:

     

    @niklasni1: your recommended switched for Cortex-M4 fails at my side.

    I'm able to build a binary, but the core crashes very early, although I'm sure that the FPU will be initialized in MIOS32_SYS_Init()

    I will debug this sooner or later, until then please use the updated common.mk, which enables M4 instructions, but doesn't select FPU instructions or libraries

  15. Use of LCD with Fast Scan Matrix

    in MIOS programming (C)

    Posted

    Hi Robin,

     

    I'm glad that the application is working at your side! :)

     

    Oh yes, I haven't considered that the DOUT pins are reverted by MIOS32_DOUT

    This can be fixed by reversing the selecting pattern (again).

     

    Replace following code:

      // transfer to DOUTs
#if MATRIX_DOUT_SR1
  MIOS32_DOUT_SRSet(MATRIX_DOUT_SR1-1, (selection_mask >> 0) & 0xff);
#endif
#if MATRIX_DOUT_SR2
  MIOS32_DOUT_SRSet(MATRIX_DOUT_SR2-1, (selection_mask >> 8) & 0xff);
#endif

    by:

      // transfer to DOUTs
#if MATRIX_DOUT_SR1
  MIOS32_DOUT_SRSet(MATRIX_DOUT_SR1-1, mios32_dout_reverse_tab[(selection_mask >> 0) & 0xff]);
#endif
#if MATRIX_DOUT_SR2
  MIOS32_DOUT_SRSet(MATRIX_DOUT_SR2-1, mios32_dout_reverse_tab[(selection_mask >> 8) & 0xff]);
#endif

    I guess, that no additional changes are required.

     

    Later, once your new board is finished, you could remove this change for "full MBHP compatibility" (because all application use this reversed pinning scheme for DOUTs)

     

     

    PS If limit the SRIO transfers to 12 rows,can I use a diode based matrix system with some or all the remaining rows of the 2 SRs for use with APP_DIN_NotifyToggle? 

     

    Yes, you can scan up to 16x16 inputs without performance decrease.

    Just change the MATRIX_NUM_ROWS to

    // scan 16 rows
#define MATRIX_NUM_ROWS 16

    the code will always use this constant to declare arrays dimensions and to calculate offsets (e.g. as you've probably noticed, I changed "KEYBOARD_NUM_PINS" from "12*16" to "MATRIX_NUM_ROWS*16" to ensure this "self-configuration".

  16. Understanding circuits - MIDI-IN diode and resistor before optocoupler

    in Miscellaneous

    Posted

    My assumptions: the 220 Ohm resistor is a common pre-resistor for the LED, e.g. for the case that somebody drives the input directly with 5V (by fault) without protection resistors at the MIDI OUT side (which also have the purpose to protect against short circuits).

     

    The 1N4148 diode: well, first it has to be considered, what happens when signals are transferred over long cables with some R, L and C (a so called Transmission Line)

     

    While the signal might look like a common digital signal, toggling between 0V and 5V (resp. 3V) at the source (*), it could look totally crazy at the sink (optocoupler) depending on the cable length.

     

    Here an extreme example (it's not a MIDI signal, but I just want to illustrate what could happen):

    8_sclk_superlong_wire_wo_termination.jpg

    As you can see, the signal can get negative transients below 0V, and positive transients above Vcc

     

    Now let's have a look into the Datasheet. It lists a maximum reverse input voltage of 5V, means: if the signal spikes below -5V, the internal emitter diode could be destroyed.

     

    I'm unsure if the emitter is in real danger (and I don't want to try this out), but if you compare with the reverse voltage of a 1N4148 diode (75V), you can see the difference - safety first! ;-)

     

    Best Regards, Thorsten.

     

    (*) not considering, that a MIDI OUT should normally configured in open drain mode, but that's another story - especially since not all MIDI devices use this mode, but push-pull instead.

    Ja, Encoder kann man "entschleunigen" ;-)

     

    Probiere mal diese Beispiele aus: http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fmidibox_ng_v1%2Fcfg%2Ftests%2Fencspeed.ngc

     

    Ich habe in Deinem .NGC gerade mal den Slow:3 Modus ausprobiert:

    EVENT_ENC    id=  1  hw_id =  1  bank=1  fwd_id=LED_MATRIX:1    fwd_to_lcd=1  type=CC     chn= 1 cc= 16   range=  0:24  offset=  0  ports=1000100000001000  lcd_pos=1:1:1  label="Shape 1      %3d@(1:1:2)%B"  enc_speed_mode=Slow:3

    so wird der Range 0:24 von einer kompletten Encoder-Umdrehung abgedeckt.

     

    Gruss, Thorsten.

[236994.010] [EVENT] id=BUTTON:65 hw_id=BUTTON:33 bank=0 fwd_id=DISABLED:0 type=CC value=1

    Was mache ich richtig? ;-)

     

    Welche MBNG Version verwendest Du eigentlich?

     

     

    ich würde gerne auch noch ein "X" für taster On im display anzeigen lassen

     

    Theoretisch geht das mit:

    EVENT_BUTTON id= 65  hw_id = 33  type=CC     chn= 1 cc= 16   range=  0:1  offset=  0  ports=1000100000001000  lcd_pos=1:10:1 label="%b"

    doch dadurch entsteht das Problem, dass der Marker auch dann angezeigt wird, wenn "Shape 1" gar nicht selektiert ist.

     

    Es gibt keine Loesung, die Meldung eines Encoders mit der eines Buttons so zu verknuepfen, dass sie gleichzeitig angezeigt werden.

    wenn ich  Core->Din->LRE verkable werden die Knöpfe abgefragt aber die Encoder bleiben ohne abfrage.....

     

    Heisst das, dass noch nichtmal Debug Meldungen ausgegeben werden, wenn Du an den Encodern drehst?

     

    Wenn Du die Encoder hinter die DIO_MATRIX Platine anschliesst, musst Du natuerlich auch die ENC Eintraege im .NGC file anpassen. Die Encoder liegen dann ja nicht mehr auf SR 1/2/3/4, sondern auf SR 3/4/5/6

     

    Gruss, Thorsten.

    Man sollte eben grundsätzlich wannenstecker verbauen und schon sind die Probleme weniger....

     

    dem kann ich nur zustimmen ;)

     

     

    Die Taster beginnen laut mios auch bei hm_id 33 jedoch passt an der abfrage noch was nicht da sie nicht abgefragt werden und mios sagt es ist noch kein Event gesetzt

     

    Tippe mal "show pool" im MIOS Terminal, was wird angezeigt?

     

    Interessant waere auch "show hw_id BUTTON:33"

  23. Use of LCD with Fast Scan Matrix

    in MIOS programming (C)

    Posted

    robin1.zipHi Robin,

     

    I merged your code with the tutorial applications, and enhanced it for two DIN shift registers.

    This was easier at my end, since changes were required at multiple places.

     

    I also added a LCD handler which outputs the last triggered row/column/value and timestamp (if value was 0)

     

    Code attached:

    robin1.zip

     

    Note: mios32_config.h contains

    // disables the default SRIO scan routine in programming_models/traditional/main.c
// allows to implement an own handler
// -> see app.c, TASK_MatrixScan()
#define MIOS32_DONT_SERVICE_SRIO_SCAN 1

    which is essential to select the new SRIO driver mode.

     

    Best Regards, Thorsten.

    Wie hast Du denn die Taster angeschlossen? Verwendest Du ein DINX4 Modul, das hinter einem LRE8x2 angeschlossen wurde?

    Dann sollte es mit dem 5ten Shiftregister losgehen, demzufolge hw_id=33

    Das wird Dir uebrigens auch im MIOS Terminal angezeigt, wenn Du mit "set debug on" den Debug-Modus aktivierst.

    I just doublechecked your snapshot.

     

    Of course: you've assigned the MP output to the volume target twice.

    One time as generic Target1 and Target2 (which is normally not required), and then again with the "hardwired" targets Vol1 and Vol2

     

    Just remove the Volume destination from Target1 and Target2
