klausuino Posted May 21, 2013 Report Share Posted May 21, 2013 When I'm using DOUT_MATRIX n=1 rows=4 sr_dout_sel1=3 sr_dout_r1=4 led_emu_id_offset=1001 inverted_sel=0 inverted_row=0 all LED's in the Matrix turn on and didn't react on incoming Midi Events like EVENT_LED id=1001 type=NoteOn chn= 1 key= 36 What am I doing wrong?

Marxon Posted May 21, 2013 Report Share Posted May 21, 2013 (edited) Hi Lukas!Did you check if your LED polarity is wrong? Edited May 21, 2013 by Marxon Quote Link to comment Share on other sites More sharing options...
klausuino Posted May 22, 2013 Author Report Share Posted May 22, 2013 The polarity of the LED seems to be right. When I disconnect the Matrix and measure the the voltage between the connectors on the DOUT Module there are still 5V. And for my understanding it has to 0V, because I never send any Midi-Event to turn on one or all LED. Quote Link to comment Share on other sites More sharing options...
TK. Posted May 22, 2013 Report Share Posted May 22, 2013 Are they also 5V if the .NGC file is (almost) empty, resp. when it only contains the RESET_HW command? Then it's probably related to a connection error between J8/9 and the shift register chain. Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
klausuino Posted May 24, 2013 Author Report Share Posted May 24, 2013 That's it. I connected the DOUT Modul directly to the core and now it works. Thanks Guys! Quote Link to comment Share on other sites More sharing options...
