What pins of SR 5,6,7 and 8 are free to use?

[mattias]

Having a bit of trouble. I cant get the leds trigger layer and step view. SR 5 is OK now pin 0, 2, 4, 6, to group select leds. But SR 6, 7, and 8 gives nothing? Anybody know what pins of SR 5,6,7 and 8 are free to use?

Anything wrong here to free SR 5 and 6 for extra leds? ???

Looks ok

Did you already check the second DOUTX4 module, e.g. with the MIDIO128 application where you can control each individual LED with Note On/Off events?

Best Regards, Thorsten.

SR 5 is OK can the rest be wrong. If so what? :'(

[TK.]

Sounds like the SC or RC line is not connected properly. Or maybe the output of SR5 is not connected correctly to the input of SR6

The SRIO interconnection test helps to check the SC/RC lines, see also http://www.midibox.org/dokuwiki/din_module

(although the page is named "din_module", it contains some debugging infos for the DOUT module as well)

The connection between the O8 output of SR5 and the SER input of SR6 has to be checked visually

Best Regards, Thorsten.

It kind of works now. But the pins sems to wrong like 4 is 7. This is the last thing for me to fix. Could it be a short in one of the leds? It´s driving me mad!!! :'(

[mattias]

Solved.. Had to use bit 4 and not bit 7 as default for SR 5 in asm file!  ;D ;D
