novski Posted July 18, 2012 Report Share Posted July 18, 2012 HI I can't see why my hardware always lights the LED of the opposite Button. Pushing Mute 1 Lights up Mute LED 8. I checked my Cabeling twice and can't imagine that i did something wrong. I will ad some Pictures of my Testboards to improve that. As you see. The IDC connectors are al the same on the DIN/DOUT side. And on my Testboard i wired the colors to the same Button as well as the LED. who can tell me why this turns out to be crossover?

TK. Posted July 18, 2012 Report Share Posted July 18, 2012 Hi, you have to consider that the LEDs are connected from the left to the right of the MBHP_DOUT module, which means: first LED connected to D7, next to D6, next to D5, etc... Buttons are connected in the opposite order (D0, D1, D2, ...) In most documentations this had been made very clear meanwhile, but not in the MBMM docs - therefore you won't find so many hints about this in the forum. Best Regards, Thorsten.
