LPC1769 Core + LPCPRESSO + 3 MF NG possible ?

MIDIbox HUIs

Hi 

 

I’m currently developing a midi controller so i can optimize the automation of my Neve VR / motorized faders. 

So I avoid any mistakes and buy the wrong circuits I’m asking you for any advices that could guide me in my little experience.

 

In the mean time, I’d like to build a HUI 24 motorized faders controller with sensitives touch + a little LED screen for each fader. (to indicate the number/name of the track)

 

I was thinking to base the whole thing on an LPC1769 Core + LPCPRESSO + 3 MF NG

 

is it possible to connect 3 MF NG on a LPC1769 Core? if yes, what is the right way to do it?

and how do I get the LED screen to work properly  for each slice/track ?

 

Thank you very much for your help

lucasmedus,

according to my understanding MF_NG contains a dedicated PIC, can be used standalone or integrated to some more sophisticated HUI and is accessed by MIDI, so there is no limit for chaining MF_NG units other that implied by MIDI protocol itself (within a reasonable practical limit, of course).

Correct me if I’m wrong, hope this helps,

freddy

the midi box ng info states: up to 32 motorfaders connected to MBHP_MF_NG modules

As already mentioned - it works! :smile:

See also the .NGC page in the user manual: http://www.ucapps.de/midibox_ng_manual_ngc.html

Search for the keyword “mf” (see especially the description of the MF command)

I´m finishing the build as the topic of this thread :slight_smile: (not trying to hijack the thread…)

 

I will use the same PSU for all modules thus no need to use the optocouplers.

 

Question:

Can I connect the modules this way: (Using only 1 cable for each of the lines below)

LPC1769 -> MF_NG 1-3

  • J11- MI1 -> MF_NG(1) - J11-MO1
  • J11- MO1 -> MF_NG(1) - J11-MI1
  • J11-MI2 -> MF_NG(2) - J11-MO1
  • J11-MO2 - > MF_NG(2) - J11-MI1
  • J5B-A6 -> MF_NG(3) - J11-MO1
  • J5B-A7 -> MF_NG(3) - J11-MI1

Hi Ole,

 

yes, this “starlike” wiring should work.
