simple control surface questions

MIDIbox SID
1

Hi,

I am about to upgrade to v2. so, in preparation, before i do anything else, i want to make the control surface.

?s:

i bought an encoder with pushbutton from smashTV. it has 5 pins, 3 on one side and 2 on the other. how do i find the specs so i know how to connect it to the digital input of my DINX4? which pin is for the button push?

and

does it matter how i order the buttons/encoder? should i put all the buttons first then the encoder?

thanks !

EDIT:

yes, thanks everyone, it was of course a simple wiring issue. i had screwed up the J1:SI din to J9:SI connection, putting it instead to J1:S0.

cool edit function.

So i finished the panel, at least soldering the buttons to the veroboard.

i have all the grounds of the buttons connected, all together, as illustrated in mbhp_32buttons.pdf.

i connected my DINX4 to my CORE. i used alligator clips to test to see if the buttons would send data, and i get nothing.

all the resistors are in place, in the correct orientation. two slots are stuffed.

help !

pics:

here you can see that the black wire is ground, and i connect the other leg of the button to a jumper so that i can obv keep the ribbon cleaner. what am i doing wrong??

Hey pkniffer.

Have you updated the io tables to match the new configuration?

hint: the file you are looking for is one of these:

setup_*.asm

5

perhaps you soldered the buttons 90° instead normal. so you wouldnt switch. i made this failure once too. it needed a hole day to find that. take a multimeter and check if your buttons are switching.

6

no, they switch, i checked with a meter.

/tilted/ - i don’t understand your suggestion immediately, so i will dig. but, could you hint a bit more?

inside the .zip file that you downloaded from the ucapps.de site, ie:

midibox_sid_v2_0_rc22.zip

there are a number of setup_*.asm files, ie:

setup_mb6582.asm

setup_tk.asm

setup_tk2.asm

these files need to be modified (slightly) to suit your hardware layout, ie to tell the core which pins your switches and encoder are attached to.

these files are then compiled into a single .hex file which is uploaded to your core via MIDI.

details of how this is done are available on the wiki

ok, i am stuck. it’s sad because i thought i was totally going to solve this tonight, but i simply can’t -

i have uploaded the setup_6581.hex to my core. I am 1000% sure that the DIN4 module’s 5 leads have good connection.

i connected the button leads from my rotary encoder to J4:D6 (menu edit) and nothing happens.

i connect it to all the other inputs, to see if i can change ANYTHING, nothing happens.

J1:RC gives 4.99v.

J1:SC gives 0.14v

S0 gives 4.94-4.95

Vd givs 4.99.

i have upgraded my SID to v2.

still no result from pushing buttons on DIN. uploaded setup_6581.hex

OK, i have spotted 1 wiring error.

The orange wire on J1 of your DIN board is connected to the wrong point. The point it is connected to is the DOUT thru.

Unsolder this point, and re-solder to the direct opposite point (ie, the middle of the other side of the header)

[tt]J1:

Vs  Vs

Vd  Vd

SI  SO

Sc  Sc

Rc  Rc

[/tt]

You want to connect to SI, not SO.

(Better yet, get a header socket, and plug it straight in)

Then you can move on to the interconnection test.

BTW, how is the SID board connected to the core? It looks a bit dodgy in the photo…

You may like to test this with just the core and the LCD, running the ain64_din128_dout128 app. Correction: you should test it like that. Anything else is creating room for error (and fried parts)

12

great ! thanks guys, i was wondering about that earlier… why there was SI on the other side of the header.

the SId is connected dogily, yes, with only half a SIL. i lost the cap :))

but, it makes sounds. it works most of the time. i’ve even used it at 2 shows so far !

once it wouldn’t boot!

will try this.

thank you so much guys for the help, i couldn’t enjoy life last night.

13

how can one recompile in OSX?

14

OK. I have changed the lead to S0 instead of SI.

when i load the ain64_din128_dout128 app i get on the LCD:

AIN                                        DIN            DOUT

crazy flashing numbers: 0          1o              1o

i disconnected my veroboard to make sure there was no shorts. i connect only the button from the encoder.

when i push it, nothing happens.

damn.

i try to connect it to the other registers to see if it’s the first chip, nothing.

AUAIMBCTG (search it) :wink:

17

thanks!

but if i ground the AINs; that’s what is causing the inability for DINs?

18

One thing at a time :wink:

If the AINs are ungrounded the PIC goes nuts trying to process the constant changes it sees in the AIN pins…

But regardless you should always fix one thing at a time. See the GROT in my signature :wink:

19

yes you’re right.. i did try to search for info about how to ground AIN input, and found nothing. will continue.

Must i ground j5, j5a, and j5b? or just one will do all inputs?

what is the best way to ground, with a SIL filled with solder?? :)_

20

j5a and b, are the same as j5, so you need only ground one or the other. You can do it however seems best to you really (sorry I always disable mine heh)
