Testing was successfull so far, but: the 3rd LED on the rh board is lit, wen I press the 3rd button. Its not ghosting, it is full bright ligting. Hard or software issue?
Also some dim ghostig on LED 1.
Backwards diode (4148) maybe? Another possibility is that there is an unwanted connection between boards.
What happens when you run FLUXTEST.ngr? Can you control the LEDs normally? By bridging Matias pins with something metallic?
What DIN events do you see in MIOS Studio when the encoder button is pressed?
Ok. The matias switches were not installed yet. After soldering all together correctly the problem was gone.
ya i too noticed some ghosting on my builts, but its not bright enough to light up the Keycap, so no big problem there.
