calculating MAX7219 resistor value? Answered
I want to use the 7219 to drive two 3digit 7segment displays with these specs. I want to use 1.85v and 18mA.
Here's what the MAX7219 datasheet states as resistor values to be used.
I'm too dumb to figure out how the resistor value is calculated. Can someone help? What would the resistor value be for 1.85v 18mA?
