bankstick gets hot...

[Guest didifeed]

hi there!

i just connected the bankstick but it's getting very hot. also the 7805. if i disconnect everything works fine. i thought it has to be a short but when checking the board i found nothing like this.

any ideas?

thx

The interconnection to the Bankstick must be faulty. Definetely some short. You´ve kinda sure burnt the 24LC. If you connect ICs, always check the voltages in the adapter first...

hm...i don't understand it... bcause i checked it and didn't find anything. there are not much connections which belong to the bankstick?!

do you think if the 24lc is damaged it gets hot also if the connections are good? i notified that i have the bridge connected at the wrong pin of the pic but i fixed this. and it doesn't work.

Normally not, but can be...

just put in your connector without the LC and if all is fine (including *all* the voltages), then put in a new 24LC.

hm.... thx but i don't really know what to measure... i can only check the current between vs and vc which must be 5v and it is. on the other pins i can't measure bcause it seems that its a very fast toggling current.

fucking bankstick.... i hate it. the connection seems to be ok.... i thought i had connected it the right way but it seems that i had swapped it 180 degrees.

but now comes the real trouble. on sending a request for the bankstick data i get back some things. but only a few blocks. and after sending a bankchange request it seems that the whole box hangs up. no pot works when the bankstick is connected.

aaaaaargh....i can't imagine any solution for this shit...

wohooooooo

works now ... i think i had to format the stick... and now it works... but the special function to change the bank don't work on the buttons ...

could perhaps anyone explain what the function in-/decrement bankstick with/without overflow means?

thx

Hi,

but the special function to change the bank don't work on the buttons

could you please explain why you are assuming that it doesn't work? You wrote that you haven't connected a display, so maybe you just have misinterpreted the behaviour? Note that this SFB function has to be assigned to the same button(s) in every bank, otherwise you won't be able to switch back or to another bank once a bank without this SFB has been selected.

eeeerrrr.... i built a general file from which i make the different setups. in this file are 8 buttons defined for the bankchange event (FF 02 00 to FF 02 07).

i uploaded two files with different pot setups (sending on different channels). if i change the bank via sending a sysex string it works. but not with the buttons.

Sorry, I've no idea why this shouldn't work :-/

Anybody else?

Best Regards, Thorsten.

[Guest didifeed]

hm....i will try and try ... somewhen it will work hehe

in worst case i could send a sysex string via a meta event couldn't i?

thx man!!!!!

[TK.]

You could also program a Meta event which just switches the bank directly, e.g.:

        movf    MIDI_EVNT_VALUE, W
        bz      MB64_META_10_ButtonDepressed
        decf    MIDI_EVNT_VALUE, W
        call    MB64_BANK_Change
MB64_META_10_ButtonDepressed
        return

switches to the bank which is specified in the 3rd byte of the button event (01-7F)

Best Regards, Thorsten.

thx

but this strange thing doesn't work at all. when i change the bank via F0 00 00 7E 43 08 0n F7 it works fine. but not with special function or meta event... but the buttons are working with controller messages. so it's no hardware fault i think....

many thx anyways for help!
