My Midiproject

[leon_reucher]

Hello everyone :)

i'm Leon from Germany and I want to design my own midi controller.
It should look exactly like that: http://www.malighting.com/fileadmin/_processed_/csm_MA_onPC-fader-wing-web_04_d5a4263569.jpg

I decided to build the LPC17 based Core and use 2 DIN, 2 DOUT (60 buttons - 60 LEDs) and two MFNG module, because I want to use 15 Motorfaders from Alps.
Is this project possible with midi box?
Where can I buy the PCBs in Germany?

I would be very happy with some feedback :)

All the best

Hi Leon

Welcome here

Your project is absolutely possible with midibox.

Few notes:

You need 8 DIN/DOUT for 60 button (8x8=64) or a DIO_MATRIX which can handle 64 led and button

I suggest you go for the STM32F4 core, which is the more recent core available for MIOS

Sounds good :)

But why do I need 4 DIN for the buttons? I thought one module with 4 multiplexers could handle 32 Inputs? :)

Okay, but I can't work with SMD, is that a problem with the STM32F4?

Ho sorry you talk about the pcb with 4DIN or 4DOUT , so yes two pcb for led and 2 pcb for button is ok :)

The only SMD part is the SDcard holder, footprint is large, no special skill to solder this with standard iron.

Ah okay :)

And where do I get all the PCBs from? :)

SmashTV aka AVI ShowTech... just google it and you'll find it.

You can also send me a PM and tell me which PCBs you need. I maybe can help you. I'm from Berlin, Germany.
