#91473 - rate of multiplex
Responding to: ???'s previous message
Jan Waclawek said:
The multiplexed setup is similar ... Current rating for both anode and cathode drivers has to be (re)considered and current limiting resistor recalculated (reduced roughly by the rate of multiplex).

Surely, not by the rate of multiplex, but by the duty factor?
