max7219 1196

How can I drive common anode 7-segment using max7219 ?
The IC is for driving common cathode displays.

you can use discrete transistor to drive them,

such as c1815.

Thanks ! But there's no mention of transistor values.

you can use not gate or buffer not to connect output of max 7219.
