Hey all,
I experience a problem while assembling my Wilba front panel pcbs for the Seq. While everything worked fine (I had left out the LEDs first), last night I soldered the LEDs and something is wrong with my multiplexing.
Among the step LEDs, every even step LED (2, 4, 6, etc) is always on and much brighter that it should be according to the used resistor.
Also all LEDs on the left hand side of the board are always one, but much dimmer that they should be.
Since I discovered this while testing during the assembly, I stopped and did not solder the LEDs above the start/stop/etc buttons, so I cannot comment on them yet.
Visual inspection of the PCB and its solder points look good. I also reheated all LED solder points by know and carefully checked for bridges among them.
As a configuration file, I use the standard file that is suggested for the Wilba panel.
Any help indicating me into a direction where to best investigate is appreciated.
Thanks a lot in advance!
Best,
Karg
