  2. Connecting 4x MF_NG modules

    in MIDIbox HUIs

    Posted

    Hi Roelli

    The NG doesn't support more than 4 MF_NG Modules and the .Hex files for those 4 Modules are in the change_id app included. So you shouldn't need to set up the tool chain. All trough your right that the link is somehow miss leading...

    post-10711-0-47380100-1425807176_thumb.p

    Then you have to go on with configureing them to "Midibox Link Forwarding point" in the "MIOS_Studio" "MBHP_MF_NG" "TOOL" dropdown. Serial Out then has to be linked to the Serial In of next MF_NG Module and the Last Module has to be set to "Midibox Link End Point" and connected to the Serial In of your Core.

  3. Encoder Filter recomended

    in Parts Questions

    Posted · Edited by novski

    Hi

    I tested a encoder filter that is recommended by the manufacturer and it works. but im not so sure about the consequences.

    I will ad a schematical drawing to show what i mean.

    The question is: can i use this schematic without troubles?

  8. Which way to go to make a 5x5 button interface

    in Design Concepts

    Posted

    Hi bubbles

    you are welcome to use my layouts i have published on github. LINK

    I have no idea of diatonic and melodic modes. Midibox seams to me to be the best Midi solution. Its realy easy to program different Banks that let you virtually multiply your 5x5 pad... 

    Maybe its best to get a STM32F4 first and try to do first steps with MIOS, it costs just about 15$... With that you can follow the tutorial on ucapps.de under Midibox_NG Project. LINK

  9. Which way to go to make a 5x5 button interface

    in Design Concepts

    Hi Bubbles

    There is a very easy way to make a such solution. The IO ports on the STM32F4Core allow a 16In and 16Out directly. (LINK -Search for DIO) So its not exactly what you are asking for because a 5x5 button pad has to be made with Shift registers. A 4x4 can be connected directly. But there is another drawback. The Sparkfun Rubberbutton PCB is layouted in Matrix form so to use this readymade PCB you will need to use shift registers anyway. I don't know the Ardiono Midi world so you might have to ask in a arduino forum to get answers about the hardware needed there. For Midibox i can list what you need:

    1xSTM32F4Core

    1xDIO_Matrix Module

     

    Or you go for a 3x8 Buttonpad from my Layout: Doku / shop whith that you will need a core as well...

    Hi Zam

     

    second question is about STM32 supplly

    I plane to use external 3.3v, 5v, and +/-15v (for AOUT and my motor driver)

    I'm fine with the STM32 J2 description for 5v supply, but i don't understand where I plug 3.3v ?

    The 3.3V is generated automatically inside a STM32F4Disco if you use that. The Chip it self doesn't do that. 

    from this document: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00039084.pdf

    post-10711-0-14716200-1416291382_thumb.p

     

    and last... i can't find any specification for all J connector regarding pin n° and function, the GND usually use pin 1 and 2 or 9 and 10?

    not sure if i understand you right...

    The Core PCB related J Connectors are described here: http://ucapps.de/mbhp_core_stm32f4.html

    In the schematic of the core you can find the Pin assignment.

  15. MIOS Filemanager NGC, IDs, Moduls and SR numbers

    in MIDIbox NG

    Hi
    Im trying to configure my MF_NG with a .NGC file. 
    Still i have problems with understanding the Code for combinations of different modules, ID Numbers and general. :smile: 
    Im Using Modules i all Layouted my self and i have tested them successfully one by one. Now the time is ready to 
    connect them together and make it complete. But i can't manage to find out how the IDs and config shold be.
     
    SO to make it not too long i made a chart of my SRIO chain I marked the unknown with a orange round "ID?" and i wold like to know what ID the next LED wold have...

  18. Midibox Button presses Keyboard?

    in Design Concepts

    Posted

    Hi

    Does anybody have a idea how i cold get midibox buttons to send an F1-12 Key like if i hit my keyboard (that one thats typing this post through my fingers right now... :rofl:  )

    maybe also through a RTP-Midi Module as well?  :pirate:

     

    Sorry for those dumb questions, but if out there somewhere there is a solution or similar, please let me know... 

     

    best regards

    Can you point me to the datasheet of device U$29/47. They are unknown by me...

    And google doesn't help...

    The connectors look a bit strange to me.

    It should be possibul to connect just through J8/9 on the core to "in" and "out" shiftregisters with just 10pin IDC Headers...

    You may have a look in to the schematics of DIN and DOUT.

  22. STM32F4 & PGA2311

    in MIDIfication

    Posted

    This Forum mostly makes MIDI stuff so you might want to have a look to the http://groupdiy.com . they make more Audio stuff.

     

    Ich hab diesen Baustein mal angesehen und weis davon noch das die Steuerung über eine serielle Schnittstelle läuft. Davon hat das STM32F4 genügend aber mit dem Midibox projekt sind diese für MIDI In/Out reserviert. Daher wird es hiermit schwierig.

    yes thats Possible. There was a Member that had the same problem a few days ago with a Motormix Fader. His was a OEM Product with 10k but without a Touch contact... It had just 3 Pins in the front... Seams like they sold varies of OEM...

     

    I don't know how it wold be possible to implement that 14k one to the midibox project. Maybe TK. can help you there...
