Testing buttons/encoders?

[program_insect]

Hello, I've wired up my 6 buttons and 1 encoder for my control surface A midibox sid...the buttons seem to be behaving badly.  Is there some way I can test to see which buttons are being pressed, and see what buttons the core THINKS are being pressed?  I didn't see a DIN test application anywhere...

Hi,

a DIN testsoftware is not required, just upload MIDIO128 - it sends an individual note event for each digital input

Best Regards, Thorsten.

TK, as usual, thanks for your quick response and help.  Hopefully you can shed some light on this situation...

I installed the MIDIO128 application like you suggested, and this makes it easier to see the erratic behavior.  The buttons seem to be working at random.  I have 6 buttons and 1 encoder.  They are wired to ports J3 and J4 of one of SmashTV's DIN4 modules.  I stuffed all 4 ICs on that module but left all the other ports unwired.  All resistors are in place, even on the unused ports.

The weird behavior seems to be related to the first button.  When I boot MIDIO128 fresh, each button will send MIDI notes at first, but then they don't work after the first press.  The first button still sends data, but after the first event (two normal midi notes), it starts sending a bunch of data at once, some string of CC values.  The other buttons seem to stop working after this.  I checked the main lines for shorts and didn't find any.

The connections look OK with a meter...the pins of the IC are high when the button is open, and go low when the button is pressed.  (am I correct to assume these are active lows?)  It seems ok there.  Evidently the core is having some problem decoding the serial output from the DIN module?  Can you spot any pattern in this mess?  Is there a simpler test I can do to see what's going on?  Is the MIDIO128 application behaving normally (sending out a few midi notes at first, then a bunch of random CC data)?  Does this seem like a problem with the core module, or can I be certain that the problem is located in the DIN module?  All other core functions seem to be ok (LCD, playing the Sid from external midi notes, etc.).

Any help would be much appreciated here...I have no idea why the inputs are behaving in this manner!  I have attached the midi output from a small test using MIDIO128, with comments.

Thanks!  --- G

one more thing:  I am unsure of the pinning on the encoder, and connected the two data lines and ground in possibly the incorrect manner...could this cause such behavior?

[TK.]

No, a wrongly connected encoder cannot cause this behaviour.

MIDIO128 sends all 128 events which are assigned to the digital inputs. So, it seems, that there is a problem with the clock line (in simple words: if the shift registers cannot be clocked, the first pin in the chain will send all events at once)

Either the clock line is not connected properly, or there is a short. This can be measured very easily: put all ICs (PIC, 74HC165) out of the socket, and use your measure to check the contacts (if it provides a "beeper", then use it, otherwise use the ohm-meter function).

Check:

  - Core J8:SC against ground: no contact

  - Core J8:RC against ground: no contact

  - Core J8:SI against ground: no contact

  - Core J8:SC against J8:RC and J8:SC against J8:SI: no contact

  - Core J8:SC to J1:SC of the DIN module: there must be a contact

Those tests all passed (assuming you were referring to J9, and not J8!).  I will start looking for shorts on the DIN module.  Any other ideas what might be causing the problem?  Is it significant that the buttons seemed to work at first, but then immediatley stopped working after that?

[TK.]

There are some other possible connection errors, which you've propably not tested (e.g. signals against the 5V line).

However, in order to simplify the debugging procedure, I've written a new test program which simplifies this:

http://www.ucapps.de/mios/srio_interconnection_test_v1.zip

from the main.asm header:

[tt]

; A CORE->DIN/DOUT Module Interconnection Test

;

; This application allows you to check the interconnections to the DIN and DOUT module

; with a multimeter. You can control the SR/RC/DO pins by sending a Modulation Wheel

; event to your MIDIbox Core - just connect a keyboard or use

; MIDI-Ox (View->Control Panel)

;

; By default all unselected pins are 0V, except for the CS# pin which is 5V

;

; The Pins are mapped to following Modulation Wheel Values:

;

;    # 0: Pin CORE::J8:DO and DOUT::J1:DO = ca. 5V

;    # 1: Pin CORE::J8:SC, CORE::J9:SC, DOUT::J1:SC, DIN::J1:SC = ca. 5V

;    # 2: Pin CORE::J8:RC, CORE::J9:RC, DOUT::J1:RC, DIN::J1:RC = ca. 5V

;

; The pin names are also visible on LCD (if connected)

;

; If you measure a voltage much less than 4.8V (e.g. < 3V or even 0V), then

; there is either a short circuit or a missing connection between

; the signal lines

;

; If a certain shift register is not working, you could measure the

; SC/RC voltages directly at the pins of the 74HC595/74HC165, please have

; a look into the schematics:

;    http://www.ucapps.de/mbhp/mbhp_doutx4.pdf

;    http://www.ucapps.de/mbhp/mbhp_dinx4.pdf

;

; The J9:DI pin can be tested with the MIDIO128 application,

; once you've ensured that SR/RC are working

; Each digital input of the DINX4 module has to trigger a single MIDI event

[/tt]

Is it significant that the buttons seemed to work at first, but then immediatley stopped working after that?

Maybe a bad soldering joint? (waggly connection)

The new program should help you to identify this.

Best Regards, Thorsten.

I am extremely grateful for your help in this debug!!!  I can't believe you bothered to post a test app just for me  8)

Using your app I was able to narrow down my troubleshooting and I finally found the problem...I had added an extra capacitor instead of a bridge on the DIN board...YES, adding components at random has the possibility of messing up the circuit!!!!  That was stupid, but then again bugs always seem to be stupid once you fix them :)

Thanks again for all your help.  Your latest DIN/DOUT/CORE test was useful for narrowing down where the problem was happening.

Do you have a collection box (donations) set up for all your hard work???

Do you have a collection box (donations) set up for all your hard work???

Look at the MIOS project site at SourceForge:

https://sourceforge.net/donate/index.php?group_id=95206

BTW: Where has the donnation link to Twin-x for the site hosting gone? Can't find it any more....

[TK.]

Hi Gideon,

I'm happy that this new application helped.

And thank you very much for the donations! :)

Raphael: I will ask Twin-X, the icon vanished during the last forum software update
