How to connect buttons and leds to MB808

[Avarges-RU]

Hi

I'm try to build MB808 in this simple variant:

1 x MBHP_CORE, stuffed with PIC18F4620

2 x MBHP_DINX4 (only 6 74HC165 shift registers used)

2 x MBHP_DOUTX4 (7 74HC595 shift registers used)

1 rotary encoder (for tempo, could also be used for additonal purposes in future)

33 buttons

35 LEDs (33 could be integrated into buttons, 2 additional LEDs to display selected layer and record mode)

And i don't find how to connect buttons, encoder and LEDs to DINX, DOUTX modules. What of DINX channel belong to shift, alt, A,B,C,D buttons etc, and where is encoder must be connected ?

Also firmware for this variant is setup_808_default.hex or setup_808_tk.hex or ?

You might be better off trying here: http://eight-oh-eight.org/phpbb2/

Especially the "Assembly Instructions" subforum might be of interest.

I haven't find answer in "Assembly Instructions" because of there instruction fo one-PCB assembly.

Also i can't register there beacuse of maybe my email domain ".ru", forum write me:

Sorry, but this e-mail address has been banned.

So please anybody who have account there please post there topic with my first-post question and give me link to read answers.

If you are building TK's variant (which I think you are) then if you look in setup_808_mbseqv3_tk.asm (within the midibox_808_v1_1a.zip file) it tells you exactly how everything should be connected. Also http://www.ucapps.de/midibox_808.html tells you how the buttons should be layed-out.
