hello

i try to build the low cost version which requires only the core board, and a single AIN and DIN ones ( not the x4 ones)

but it is specified 16 faders for the AIN, why? if i use a single AIN there'll be only 8 faders? no?

???

if someone can help me, or knows where i can find informations for the low cost version

thanks a lot

I dint clearly understood but... With 1 AIN u have 32 analog inputs! You can connect as many pots or faders as you want until you reach the 32!

Hi,

It's even possible to build a least-cost version without an AINX4 module.

See the comments in main.asm:


; Number of connected pots
; Allowed values: 1-64
#define DEFAULT_NUMBER_POTS 64 ; number of connected pots
;
; Multiplexers (AINX4 modules) connected? -> set this value to 1
; No multiplexer connected= -> set this value to 0, allowed number of pots in this case: 1-8
#define DEFAULT_MUX_ENABLED 1 ; enable multiplexers
[/code]

In "unmuxed" mode the pots have to be connected directly to the J5

Best Regards, Thorsten.

Hi bount,

you are mixing digital inputs with analog inputs. The J5 solution is only for people who don't want to use analog pots - the example is directed to programmers (not for users)

You have to connect your pots to J5, there is no other port where you could do this.

Buttons have to be connected to a DINX4 module

Best Regards, Thorsten.

ok

actually i'd like to build a very simplified midibox64 in order to transmit a channel control 4 midi signal  by moving a analog pot.

so i want to know if i have to build this version http://www.ucapps.de/mbhp/mbhp_midibox64_lc.gif

or if  it's possible to have a more simplified one for my little "head"!!

oh i didn't understand this explanation:

No multiplexer connected= -> set this value to 0, allowed number of pots in this case: 1-8

how you can have 1-8 pots without any AINX4 connected?.

thanks a lot.

bount.

You have to change the settings in main.asm of the midibox64 application to 8 (pots) and 0 (no multiplexer), rebuild the application (like described here: http://www.ucapps.de/howto_tools_mpasm.html), and then you can connect your pots directly to the pins of J5. It shouldn't be so difficult - just try it out and you will understand what I mean ;-)

Best Regards, Thorsten.
