Here I go again. :whistle:
Just trying to understand the wiring of the LED Button Matrix.
Looking at the DIN diagram it has J8 D1 being split to 4 wires then each of the split wires goes to a separate 1N4148 diode then to the matrix row buttons and then from the buttons straight to the DOUT board J4 D2-D5. Am I right so far?
Then the led cathodes get wired to the same J4 D2-D5 on the DOUT but go before the resistors? Is this correct?
I am lucky I have some spare diodes from Wilba's
