DIN with Encoders AND Buttons

[jholzer]

Hi!

I have a DIN-Module that should be connected to 4 Encoders plus 24 Buttons.

I tried to configure, but unfortunately i only got MIDI-signals from the very first pin of the first IC (J3)

When i connect an encoder to J3, it reacts like a button (DIN_NotifyToggle). The same when i connect a button to J3.

What is kind of weird is, that not only one single MIDI-event is sent, but events for all MIDI-Notes (at least, that´s what it seems like)

Connection to any other pin than J3 does nothing at all.

So i guess i have to do some configuration in MIOS. But i couldn´t figure out what...

The question is:

How do i configure MIOS to work with this mixture?

I hope anyone can help me!

Thanx a lot

have you declared all encoders in the mios_table.inc file (in the mios_wrapper folder)?

have you set the right number of SR at the beginning of the main.c file of your app?

Hi!

My Encoder-table looks like this:

MIOS_ENC_PIN_TABLE

;; encoders 1-16

;;        SR  Pin  Mode

ENC_ENTRY  1,  0,  MIOS_ENC_MODE_NON_DETENTED  ; V-Pot 1

        ENC_ENTRY  1,  2,  MIOS_ENC_MODE_NON_DETENTED  ; V-Pot 2

        ENC_ENTRY  1,  4,  MIOS_ENC_MODE_NON_DETENTED  ; V-Pot 3

        ENC_ENTRY  1,  6,  MIOS_ENC_MODE_NON_DETENTED  ; V-Pot 4

ENC_EOT

and in Init i copied a passage from an example:

//Buttons

// set shift register update frequency

MIOS_SRIO_UpdateFrqSet(1); // ms

// we need to set at least one IO shift register pair

MIOS_SRIO_NumberSet(16); // for 128 pins

// debouncing value for DINs

MIOS_SRIO_DebounceSet(10);

I don´t know if this config is right as i´m using just one DIN which has 4 ICs.

[dstamand]

MIOS_SRIO_NumberSet(4); // for 32 pins

I don´t know if this config is right as i´m using just one DIN which has 4 ICs.

Use 4 = Din_4x module.

I tried this. But no change at all...

When pushing a button connected to the only working pin i get the following messages (copied from MIOS Studio):

What did i do wrong?

* What application do you use?

* Can you either zip and attach or post your source code?

* What do you mean by the "only working pin"?

[jholzer]

Hi!

I use a self-made application based on MIOS and the C-skeleton.

Attached is a ZIP containing the main.c and mios_tables.inc that i modified from the skeleton.

There is 1 DIN4X and 1 AIN4x (not tested yet).

On DIN the shall be 4 Encoders on the first 8 pins, the other 24 pins are connected to Buttons.

i'm not sure but it seems that your app send midi data even when encoder don't move (-->if incrementer > 0... else .. (so else is when incrementer == 0 too )..

[jholzer]

No.

It only sends if a encoder is moved.

The problem is, that only the very first pin acts like a button.

All Midi-Events come from DIN_NotifyToggle, i got no event from ENC_NotifyChange, where they should come from if the pin is <8 (=> encoder-table>.

And DIN_NotifyToggle sends not one event (i tried this also with a button conntected to pin 1) but many (see post from 17-04-2008, 23:13:03).

Looks like the shift registers are not shifting.

But why?

[nILS]

i'm not sure but it seems that your app send midi data even when encoder don't move (-->if incrementer > 0... else .. (so else is when incrementer == 0 too )..

Basically correct, but the function isn't even called by MIOS when no encoder is moved ;)

All Midi-Events come from DIN_NotifyToggle, i got no event from ENC_NotifyChange, where they should come from if the pin is <8 (=>encoder-table>.

So the DINx works well for buttons, just not for your encoders? What encoders are those?

[TK.]

If the first DIN sends multiple MIDI events, it seems to be a problem with the RC or SC clock line

Some time ago, I wrote a troubleshooting guide which should help to find the wiring or soldering error: http://www.midibox.org/dokuwiki/din_module

Best Regards, Thorsten.

[jholzer]

That´s it!

I had a soildering-problem on the SC-line.

Thanx 4 helping!
