I'm about to breadboard a circuit to drive six displays using these components. Cathodes will be connected to the ULN2803 and it will be driven by the HT16K33 in a 16x6 multiplex configuration.
I was researching the way to calculate the series resistor value for each multiplexed row segment when I realized that anywhere from 0-6 segments in each row will be on at the same time, so I'm stuck. Can you suggest a better way to do this? I want to stay with the HT16K33.
Thanks in advance.
