    Thanks a lot for sharing this Rolf, this is really nice from you ! I download the scheme and give it a deeper analytic review . By the way this Xmega board sounds to be a nice tool, i'm wondering about how hard it should be to port the scope thing code to MBHP_Core32 In the end this is going to lead to a MB-Scope project :D regards, Jerome

    yeah i know . i will quote the same than the other thread you answered me : That was the "Why" of my question.

    Hi novski ! This time i am not going on a new build , but just filling the wiki :) The STM32F4 Core has an issue with midi outputs: From Ucapps page : so that's why i asked for another way to connect it =) ,that's all . Thought about I2C as well as from my researches it seems to be the best way to communicate with a PIC ? Edit : I2C also conflicts with MIDI I/Os, i forgot about it.... best regards , Jerome

    Another question about the MBHP NG platform: How to connect the Motorfader NG to new core32 without using MIDI (STM32F4)? Wich best way and protocol to use? (as well as MIDI I/OS on new core are already quite "pin-loaded") thanks in advance, Jerome

    Hi, just wondering if the I2S DAC module still useful with the new core32 STM32F4?
  6. Psykhaze
    Thank you =) Trying to keep the things going on ^^ Giving much updates to the MBHP part of the wiki. Will continue to fill the wiki instead of filling some private excel files =D I am just giving some structure / readbility / visuals to some existing but splitted data ; can also make the point for myself at the same time about what i know about midibox. If there is any point you want to be filled before another,just tell. Do not hesitate giving feedback also =) greets, jerome

    Was just having a look @ mouser/embedded artist and the LPC1769 board linked in the Ucapps Core page is now obsolete (924-EA-XPR-003) Is the replacement (924-EAX00242) ok to fit the core lpc17 board? greets, jerome

    Nice, this kind of PCB is always helpful when you turn the things modular :p (or old school-synthed) I would just say the front connector is quite outdated nowdays. But if this is the way to plug it to your SeqV4 =) The All-in-one tested PCB would be surely a great add to midibox projects. A standalone version with Core32 inside and MIDI Plugs would make it even better. I send you all my positive vibes on your work. Waiting for a video :p greets, jerome
  9. Psykhaze
    You're welcome, my pleasure =) I will continue to fill as much as i can the wiki these next days, greets, Jerome
  10. Psykhaze
    nice stuff ! This is another yet MIDI>CV ?
  11. Psykhaze
    By the way , after exploring the wiki a bit more, it's kind of really the mess and it hurts my eyes. Much informations is there but no one should get into because of readability problems : There are many large blocks of text and too few pics in many section , Is it possible that I redo some layout in several section? I mean without deleting any content , just making it more organized & cool to the eyes? (that's a thing i do well )
  12. Psykhaze
    @Sauraen Dude , you made my day ! and beg my poor english xD Edit : I just think later about it but maybe you already have designed some of the components i listed ? I'll try to reproduce them by myself anyway, but it was to compare in the end
  13. Psykhaze
    HI all, just started few new wiki topics, as told in the title. http://wiki.midibox.org/doku.php?id=electronics_basics (translation from some of my blog articles and some addings, corrected by Sauraen & Latigid) http://wiki.midibox.org/doku.php?id=kicad_an_open_source_alternative_to_eagle_for_pcb_design http://wiki.midibox.org/doku.php?id=freecad_an_open_source_software_for_technical_drawing Last Second edit : Updated link Another new topic in wiki : http://wiki.midibox.org/doku.php?id=digital_electronics Feel free to have a look and give feedback! If you can also add coherent content, if you can/want, would be great.

    Sometimes some circuits are dealing with bipolar inputs by inverting the negative part, that's why i asked . So it's positive voltage feeding but not from zero and up to +15V. Thanks you for this precision =)
  15. Psykhaze
    I just made some basic Filling as well as i am new to Wiki syntax, i am a bit struggling to get the things where i want xD I'll make a 4 parts video tutorial covering each 4 parts of the flow process I described . i'll do it through a complete flow making DIN and DOUT PCBs from the start. Please give feedback about this =) Edit : Not on Topic but also also added a FreeCAD section in http://wiki.midibox.org/doku.php?id=basics find it here : http://wiki.midibox.org/doku.php?id=freecad_an_open_source_software_for_technical_drawing
  16. Psykhaze
    @Phatline I am coming back to the Accent Signal. Is it 15V Bipolar or not?
  17. Psykhaze
    @Phatline : It really looks quite the same than in the schematic, at least to me did not looked well . My bad once again.
  18. Psykhaze
    Hey that res networks sounds cool =)
  19. Psykhaze
    sure :D A resistor Array is much better in here , i talked without reading. my bad
  20. Psykhaze
    Yup , i'm ok with Latigid SMD Soldering isn't the best DIY way. To save space,maybe mounting resistor vertically would help

    Just Opened a wiki Section. it's Here : http://wiki.midibox.org/doku.php?id=kicad_an_open_source_alternative_to_eagle_for_pcb_design and from the http://wiki.midibox.org/doku.php?id=basics Section

    From my midibox partlist, the commonly used components are : (i put modules they are used in and a mouser ref for each) ICs : -74HC165 - DIN - 595-CD74HC165EE4 -74HC595 - DOUT, TIA, SID, AINSER - 595-CD74HC595E -74HCT541 - CORE32 - 595-D74HCT541E -74HC00 - MIDIO - 595-CD74HC00EE4 -MCP6004 - OPL3-5V - 579-MCP6004-E/P -MCP3208 - AINSER - 579-MCP3208CIP -MOS4051 - AINSER - 595-CD74HC4051M96 -TLV5630IDW - AOUT_NG - 595-TLV5630IDW Triacs: -6N138 - MIDIO - 512-6N138M -78L12 - SID - 512-LM78L12ACZ -2N3906 - TIA - 512-2N3906TA -BC547 - SID - 512-BC547BTA -BC337 - CORE32 - 512-BC33740TA DIP/DIL Sockets : - DIP 8 - MIDIO - 653-XR2A-0811-N - DIP 14 - OPL3 , AOUT , MIDIO - 653-XR2A-1401-N - DIP 16 - DIN,DOUT,TIA,SID,AINSER,CORE32 - 653-XR2A-1611-N - DIP 20 - CORE32 - 653-XR2A-2001-N - DIP 28 - SID - 653-XR2A-2811-N - DIP 40 - TIA, AY - 653-XR2A-4011-N - DIL 5x2 - ALL - 649-66953-005 - DIL 25x2 - CORE32 - 649-66953-025LF Resistors (that are not 1/4W thing) - 10? resistor network - DIN - 220? resistor network - DOUT - Pot 10k? - CORE32 - Pot 220? - AOUT_NG I will start the KiCAD Lib from this list. And after making my mind , the best to start the KiCAD Tutorials is a full process from schematic to PCB with DIN/DOUT Modules and then increase difficulty by making the TR-606 BD/SD process

    You pointed out something really interesting @latigid on . Sharing the finished PCB Designs gerbers is to me not a good idea. Few peoples with no knowledge in electronics and interested only by business oportunities would be able to steal TK's work. The DIY is not only about saving money , but understanding too, and sharing. I think making this little Library with commonly used components (like serial registers etc) in various midibox projects is a better idea than sharing the all-ready PCB gerbers. KiCAD is to me a good Open Source alternative to eagle who could really fit for the midibox project, and avoiding the pain-in-the-a** library things would be cool. Sharing a little PCB design like a DIN/DOUT seems ok to me, but sharing like the PCB of Core32 seems to be a bad one. I think it's better to let people produce their own PCB ; If they have the tools like a library and access to video tutorials, nobody would have excuses. DIY means Do It Yourself, isn't it ? Today/these next days i am going to prepare a full KiCAD Tutorial from Schematic to PCB with BD/SD sections of the TR-606. I will go at the same time through filling a wiki section . To me creating a new "Tools" section in MIDIbox Hardware Platform (MBHP) is thegood place to be
  24. Psykhaze
    Hi Sauraen! Knew was a good idea to tag you, your advice is always welcome =) happy you explain again to everybody the limits of trying making a library. But there is components like IN/OUT Serial Registers wich are commonly used in many projects, was more thinking about it. Ok pin design isn't a big deal on it but that was for the principle. I am trying a run on KiCAD tomorrow with BD/SD Section of the TR-606 . Thought it would be the right time to make the point with my knowledge by starting filling a wiki part (still don't know where to put it btw) and starting to work on some vids
  25. Psykhaze
    By the way, what is the voltage range and signal expected in TRIGGER signal? PULSE 5V?
