I want to drive some large (2.3") 7 segment displays with a MAX7219. Voltages greater than 5V require some extra components and this circuit shows how to accomplish this for common cathode displays. I have some common anode displays and was wondering if there is a simple way to alter the linked circuit so that it could drive these displays. Would swapping the UDN2981 and the ULN2803 accomplish this?
Thanks!
