Which button's which?

[Guest ErikM]

Hi all,

I've built a prototype just for playing and testing. So my prototype just has a DINX1, just one chip.

Is it correct that if I use the m64 firmware the first four

buttons (d0-d3) act as button 17-20 (tested with midiOx and internal setting) and the second set of buttons (d4-d7) act as menu/navigating buttons?

Not that I worry (it's working, isn't it :) )but I'd like to know.

Regards, Erik

heya!

i dont know because i didnt do that never,but it seems to work.i think you can do one think:load de example ain_din_dout,put the 8 pins of ain inputs on the core to ground(to avoid unwanted midi signal)and try the buttons,in the display will appear button id,i suppose that in the midiox so.try it.

;D

After investigations: my conclusion is that everything is allright. Still I wonder why buttons 17 to 24 are connected to the first chip, or perhaps I should refrase that to: Why did somebody call the first chip-buttons 17-24?

Why did somebody call the first chip-buttons 17-24?

Oh, this has some historical reasons - in the first months I just wanted to prevent that everybody has to change the wiring of his box with every new release. The very first MB64 supported only 16 LEDs and 24 buttons, and I improved the driver successively.

However, today the shift registers are freely assignable to the button and LED entries in main.asm (thats the purpose of the DIN_MAP and DOUT_MAP). Als the menu buttons are free assignable to any pin (not only to the first 64, but also to the remaining 64 digital inputs...)
