Avarges-RU Posted February 17, 2010 Report Share Posted February 17, 2010 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 ?

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. Thank you.

philetaylor Posted February 17, 2010 Report Share Posted February 17, 2010 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. Phil Quote Link to comment Share on other sites More sharing options...
