detend alps encoder on mb64e

[Lide]

hi all,

today i tested my mb64e-core module with a connected din, which has a alps ec11b 20 detend encoder connected. i want to use this to scroll up and down the scenes in ableton live. for this i need two different midi-notes: one note at a click when i turn the encoder to left and another when i turn the encoder to right.

i tried it with my configuration but the midi monitor showed, that there are sent 0 and 127 both on two channels (think it was 8 and 9) by one click. does the logical algorithm not work  with these encoders? can i use them at all?

i think this could be fixed by changing some parameters, but after searching in the mb64e-app-code, i´m really frustrated, because i couldn´t find anything where i see which encoder type has to be selected or what i can change to make this thing work.  :'(

so anyone who has more skillz in programming and electronic, who can show me the way into the light?

thanx&greetz, lide

This sounds very strange to me. The only thing I can suspect is that you have connected the encoder in AIN.. not to DIN.

Bye, Moebius

p.s. These simple things are NEVER bugs in TKs code

hi,

you mean i only have to connect the encoder and it got to work without configurations in the mb64e-app? no parameters to set? i found that picture about the different encoder modes (http://www.ucapps.de/mios/mios_encoder_modes.gif). they work without telling the software which type is connected?

and how does the app "know" if there´s a button or an encoder connected? or is this not necessary?

The modes are set in mios_tables.inc. Pleas read the comments of TK in this file.

and how does the app "know" if there´s a button or an encoder connected? or is this not necessary?

From main.asm:

; This DIN map allows you to customize the MB64E application to different hardwares

; The MB64E dump structure allows the use of up to 64 buttons, they are grouped to 8 buttons per shift register

; Define the used shift registers for the buttons here

; the shift registers are counted from one - means: 1 for the first, 2 for the second, etc...

; mark unused button groups with 0

;; NOTE: by default, the first two DIN shift registers are used for the encoders

#define DEFAULT_DIN_SR_PIN_01_08 2

#define DEFAULT_DIN_SR_PIN_09_16 3

#define DEFAULT_DIN_SR_PIN_17_24 1

#define DEFAULT_DIN_SR_PIN_25_32 4

#define DEFAULT_DIN_SR_PIN_33_40 9

#define DEFAULT_DIN_SR_PIN_41_48 10

#define DEFAULT_DIN_SR_PIN_49_56 11

#define DEFAULT_DIN_SR_PIN_57_64 12

i couldn´t find anything where i see which encoder type has to be selected or what i can change to make this thing work. 

Hard to believe... These settings are discussed in so many forum threads!

Thanks for the hint. Although I´m a little bit confused right now. In the mios_tables.inc I changed the mode to detend encoders.

But at the core-page i read that the DIN with encoders has to be connected to core´s J6 when using MB16e. Is this also right for MB64e? Maybe then my former configuration was wrong, because I connected the DIN module with encoders to J9 of the core-module.

However, I changed it and connected the DIN with encoders to J6 of the core and now i cannot get any midi signal out of core... ???

No. Have you really read the MB64e page? I doubt again.

Hi,

I´m sorry.

Maybe a few words about my complete Midibox-Setup are helpful for further discussions:

I want to have a MB64(ID00)+MB64E(ID01) linked together in one box with 71 buttons (64 of them with leds), 44 pots, 9 faders and 2 encoders for controling ableton live.

The pots and faders (=2xAINX4), the 64 buttons with the leds (=2xDINX4 & 2xDOUT) and the LCD  should be connected to the MB64-core (ID00) . This core is the Midibox Link EP.

The other 7 buttons (including the menu buttons) and the 2 encoders are connected to one DINX4 which is connected to MB64E-core (ID01) as Midibox Link FP.

But since i don´t have my front- and backpanel yet (DHL sucks :( ) I wanted to test the pots/enc on the supposed cores before connecting&linking all together.

The pots seem to work now on MB64-core - after having some grounding problems.

Enc still does not work properly on the MB64E-core (see above).

So will it work if i connect the DINX4 to J9@MB64E-core and connecting the 7 buttons to J3 & J4  @DINX4 and the encoders to J5 @DINX4 without changing the MB64E-app-code OR what will I have to change if it does not?

Sorry for my wack skillz in coding and electronics...

Thanks again.

This should work. This is the MB64e standard configuration. (SR5 to SR8 for Encoders; SR1 to SR4 for Buttons)

Ok  ;D

After testing several connections of the DIN and changing some app-code I got my encoders work now.

Thanx a thousand times for helping!!!

Next I will do is mount all modules in my midibox and link them together.

So I´m waiting for my front- and backpanel...  8)
