  1. I currently want to build the MIDIO 128 v3 (including the lpc17) so i managed to buy a lpxpresso1769. The components are easy to get, but i didnt find any way to get the PCB. Is there any way to buy a PCB online thats already made? oh, and does anyone know what the dimensions of the PCB are? i just found the datasheet including the Value 100 x 120, but im not sure about the unity. Greetings, Kilian
  2. Hey everybody As it seems, I fried the R/W output pin of my LPC17 (p1.27 of the LPC1769 xpresso). When I moved my Synth from the cardboard housing over to the new wood case, I accidentally plugged the 5V supply into J27 next to J2, the actual supply pins. The 800mA slow blow fuse blew instantly, so I assumed, that I had shorted 5V to GND of J27 but everything except for the fuse was alright. Of course, the move from one housing to the other lead to a lot of cables being too short and a bit of debugging due to shorts with the front panel and so on and so forth. The last thing t
  3. Hello Guys, Some days ago i finished my first ucapps project, the Core_LPC17. I immediately connected it to my PC (windows 7 64-bit) , bit he wasnt recognized by MIOS studio, so i installed the GM5 driver. Hes displayed in the MIOS selection line (Screenshot 1) , but still no ucapps device is dedected. so i tried to connect the device to my old Laptop (winXP) and there the connection worked perfect (so it seems to be a software problem). does anybody know what i could have missed or how to get the connection running? -Gm5 is installed as mentioned above - I tried to restart my
  4. hi, i'm trying to compile the SVN trunk of midibox_ng_v1 for LPC17 under MacOSX 10.11.6 using the gcc-arm-none-eabi-4_7-2013q3 toolchain but i run out of memory ("RAM overflowed") at the link stage. any recommendations? should i comment something out, or go back to a recommended tag, or can it be a problem with my setup? i started fresh from scratch (no residual build files messing up the linking) thanks!
  5. Hallo Zusammen, ich habe vorgestern mein erstes Ucapps - Projekt fertiggestellt, den Core_LPC17. Habe ihn sofort an meinen PC (windows 7 64-bit) angeschlossen, aber er wurde von MIOS nicht erkannt. Also habe ich den GM5 Treiber installiert. Der GM 5 erscheint auch in der MIOS Auswahlliste oben (Screenshot) , aber trotzdem wird kein Gerät erkannt. Deshalb habe ich es an mein Altes Laptop mit Windows XP angeschlossen. Da hat alles einwandfrei Funktioniert. Also scheint es ein Software-Problem zu sein. Hat irgendjemand eine Idee, was ich vergessen haben könnte bzw. wie ich die Verbinfung he
  6. Hi all, i've connected a fatar df 61 keybed (now 49 keys working fine with midibox kb (v1.016) on lpc17) and now changed fw to midibox ng (v1.033) and have got some problems. The order of the keys is wrong (rows etc.) and no velocity. No problem I thought and tried to adapt the keybed by setting kb 1 and tried debug mode via miosstudio but this is not working. The parameters seem to change but no visual or audible effect. The wrong order and missing velocity is still there. So what is wrong or do I have to compile the firmware first with other settings, if I want to use it with my keybed? Best
  7. Hi guys! I've just started testing of my first MIDIbox as a complete set, configured for midi2CV application. It's based on LPC17 core; aout_ng used for CV output. Currently it's running under Midibox_ng_v1_032 and configured for high-resolution CV. CV output is okay, however I encountered a problem with gate. There is no signal at DOUT ch. 1 through 7 upon key pressure. Sure, fwd_gate_to_dout_pin... command is applied in configuration file. I checked j8/9-DOUT connection twice - it seems to be ok (according to diagram). I see that "DOUT off" when I press shift and "all DOUT pins inactivated"
  8. hey guys, i postpone my "building-my-own-seq4"-project. i only bought the lpc17-kit from smash tv, and as i need some bucks, it´s better, if i try to sell it, and reorder it, once "the times they are a-changin". as for the kit: i only opened the parcel, as did customs before, and inside there´s the still sealed, unopened lpc17-kit, including almost everything, you need to assemble the "core" of a seq4, including the lpc17-pcb. as i payed customs, it seems reasonable, that people in/next to germany buy it, if interested. the kit can also be picked up, if you live in hamburg. p
  9. Hello, I am trying to get started with the LPC17 CORE module for my Midibox Seq v4. I am following the instructions that are posted here: http://www.ucapps.de/mbhp_core_lpc17.html following the steps for installing the MIOS32 Bootloader I've downloaded the LPCXpresso 5.2.6 and I have installed and registered. It does say this now on the Splash Screen: LPCXpresso5 is fully activated. The instructions on the above link indicates this: "After the LPCxpresso IDE has been opened, create a new "FreeRTOS project" for LPC1700 controllers. This project is only used a
  10. Hi, I am new to the forum and new to MIDIbox. I built the LPC17, DOUT, and DIN modules this week and am trying to get them working properly with the tutorials and examples. Playing around with the SRIO Demo (trunk\apps\examples\srio) I found that the DIN module is working properly (when I toggle a button I can see confirmation in the MIOS terminal and on the connected LCD. However, I am unable to get any response out of the DOUT module; more specifically when I toggle the buttons the LEDs remain lit. I checked every output pin on the DOUT module with a multimeter and found that every pin i
  11. Hi all, I'm thinking of designing a new controller for general use with various programs on my computer, and to fit with what I want I will probably be using the midibox NG project. However, I was thinking it would be really cool to incorporate this capacitive touch sensor into my design: https://www.sparkfun.com/products/9695 So for a person with only a basic understanding of electronics and programming, is anyone able to help suggest ways to implement this into my design? Thanks :)
  12. Hey. This is my first time posting and my first build. Thanks for all the hard work on this project. Very cool stuff! I have a few questions on getting started. I have the LPC17 setup with the SD and working over USB. My configuration is going to be: LPC17 (2) DIN to control 21 Rotary knobs and 20 buttons (1) MF_NG to control 1 Motorized Fader (Alpha) (1) DOUT for LED I won't be using any midi ports for this project, it will be USB-MIDI. I have J4B of LPC17 connected to J11 of MF_NG. From here, I have no idea what to do to be honest. :smile: I would love to make a detailed PD
