How to use STM32 Nucleo-f303k8 to print in 1602 LCD(without i2c) with STM32CUBEIDE?

[sakkigoni]

I have a correct circuit and could print in LCD in arduino IDE using the above mentioned board. To do in STM32CUBEIDE I dont know what libraries are needed and how to code there. Can someone please guide me? There are no videos online or no resources regarding this so I couldn't be guided. Thanks in advance
