  1. Lol,  it was too early in the discussion maybe  Sorry
  2. Hi ! It may be because English is not my native language but I have to say : The LCD part of the CORE_STM32F4 Module page is not clear at all. Because of that (and because I didn't take the time to check the VCC and Ground BEFORE soldering) my LCD have made this typical sound of... fire starting. I have followed this page: http://www.ucapps.de/index.html?page=mbhp_lcd.html / MIOS32 Connectivity / Wiring Diagram for 2x16: mbhp_lcd_mios32.pdf (as my LCD have all the pins in line). But after that... the wire 3 is NOT V0. So the sentence "Order of wires is matching with flat ribbon cable" doesn't work. And I can't figure out how it can work (with the J15 port at his place). For me all the wire have to be twisted two by two. It's too cold is the garage right now, i will try tomorrow.
  3. Take a look: There was no chance that I could find it with the search function but... By looking deeper and deeper in the forum I fall into this tread.  
  4. Yes ! Theses are good tips ! I'll try by myself now with standard connectors. I have to learn and it's a useful exercise. And with the files you provided it will help too. Thanks !
  5. So... It take way too much time to start using eagle. What a nightmare for a such simple board: Note that i havent check the reverse/mirror pin thing yet because I have a question first: how to make the upper solder pads to touch the border of the board ? This way it will be possible to solder this board to a 90° angle to the LCD with no wire. And then I will find how to add the ribbon connector schematic..
  6. Hi ! I'm currently reading the Midibox NG manual. Is it helpful if I write some parts here that (in my opinion) could be changed ? Like in this page: http://www.ucapps.de/midibox_ng_manual_fs.html  "Today we would prefer to use Fairlightiii's premade PCB solutioninstead - more informations about this once I get my hands on the PCBs! :-)" As theses PCB will never be reedited, it is no more relevant ? So. If comments like that is cool for you, I can continue. Or if it bother you, I can stop. But please note that by using my phone to read the doc and write on the forum, I have no way to format and use the code tool.
  7. Hi ! I'm happy to say that the core is okay, i've soldered my second LCD and... it's working GREAT ! See the lasts pictures ;) https://photos.app.goo.gl/5bR4r2ivZe5dgYYW9 @TK. I've added three of them in the Gallery, please fell free to use them if you like.

  11. Clear to me ! Thanks a lot ! Lesson learned : check, double check, triple check before power up !
  12. Oh I see the triangle in the first photo ! I did miss a big I formation then, thank you ! Is there a page with ribbon tip and tricks ?  And sorry that I didn't understand you the first time. Language barrier maybe ;-)
  13. It doesn't look true... Here is what happened when I clamped the ribbon (with V0 at pin number 04) : ________________________ |15 13 11 09 07 05 03 01 | |16 14 12 10 08 06 04 02 | __________----___________ And I can't mechanically change this order can I ? The red strip of my ribbon will always be clamped to the top right of this schematic (The last wire will alway be at the bottom left too). The two opposite side of ribbon cable will alway be in diagonal, top right / bottom left as i understand. Did I miss something ?
  14. The multimeter as show say "it doesn't". The V0 "bip" on the wire 4. And yes it is like Hitachi 
  15. I'm back from the garage. It's -1°C ... cold. Anyway here is a google album with the pictures i have taken, just under the midi-notes attribution chart: https://photos.app.goo.gl/5bR4r2ivZe5dgYYW9 You can see where is the notch of the ribbon head, the big clear labels on the LCD PCB, the labels hidden under the "big black plastic of the ribbon port that hide" and finally, how I test and found where the V0 is.     Please not that I've tried to de-crimp the ribbon yesterday, but it was well crimped before the incident.
  16. It look MIOS8 compatible, not MIOS32. But the idea is cool. With 90° pin header the PCB + LCD + Cable will be "flatter" . I have to reinstall eagle and sketch the idea ! Thanks !
  17. I put the cable on the bottom and the soldering on the top. https://www.ebay.fr/itm/1602LCD-Blue-Yellow-HD44780-Character-Display-Module-5V-for-Arduino-Raspberry-Pi-/263750988179?varId=562961334972&txnId=2349798667016 but there is big labels. I'll take some pictures tomorrow ;-)
  18. Oh.. I think I did that, if wire 4 is V0, then wire 3 should be RS ! (Wire 1 and 2 swapped, 3 and 4 swapped, and so on)
  19. Thank you both of you ! In fact I'm an old newbie here. My core was made in 2016 (edit: the metadata of my pictures says October 2017), and I follow uCApps for more years than that ! Maybe 2004 (... Wow.. so long ?..). It's okay for me to broke an LCD, but the point here is about the indication on the website, they are confusing about the ports of the STM32F4. I mean... Really.  But on the other hand, I should have double checked the vcc and ground for sure.
  20. Multimeter in "bip if wire" position. V0 is not in the wire 3 but the wire 4. Sorry I didn't check my messages before posting (baby things to do...) And forgot to mention it. Yeah the pinout of the LCD is very clear and written on the PCB. The problem is one the other side, as I have the big black plastic of the ribbon port that hide all the important information written one the core PCB. Had to remove it to check... After the fire. The LCD is probably dead (in French: le son (juste le son) d'un petit feu qui crépite est mauvais signe, la nouvelle odeur aussi, mais je testerais le nouveau câblage... Au cas où) but yes, I have an other one ! Lucky me...
  21. Search MBHP_AINSER8 module PCB

    Topic ready to be closed. I have taken 3 pcb to 5€ each so... it's good for me. If I don't use the 3, i'll sell the two unused (for guess.. 5€ + postage in europe) ! I'll tell you if and when it will be available !
  22. Hi everyone ! Do anyone have a MBHP_AINSER8 PCB to sell ? With an invoice to France and a payment with Paypal ? I only need one of it so... http://www.ucapps.de/mbhp_ainser8.html Thanks !

    Thanks ! I have some time as I have to build AINSER8 Module (foot controller without AINSER8 doesn't work for me). Regards, Wapata

    Hi ! Too bad for me, the scanmatrix of my keyboard doesn't match the ones of the project. The Yamaha DSR-2000 is arranged this way (see attachment) It look like "midibox_kb_scanmatrix_type1.pdf" but with velocity.
