Best practice to interface multiple 7 seg display with STM32F030R

Greetings ,

I have interfaced 7 seg displays with 8051, but this is my first time working with STM32 mCu. Is there any recommended practice to interface multiple 7 segment displays with STM32 mCu ? I want to use Common Anode 7 segment displays in my new project and i want to interface 18  7Seg displays.

I'd supposed you'd interface them either in a manner materially similar to your 8051 implementation with GPIO, or you'd use a driver chip and a shift register type method
