How to properly use HandleTypeDef in librairies

Hello,

I have a temperature sensor connected to the I2C1 bus of my board. To help me with basic configuration I use STM32 Cube to generate the base of my code. I usually then go on to write my own libraires to use at later time. It is probably not the most optimal, but helps my understanding quite a bit. Somewhere close to the top of the code there is multiple (I2C,TIM,USAT)_HandleTypeDef. How to I go around using these in other files? Do I need to redefine them in all the file I write them in or simply pass them around as arguments to functions?

Thank you in advance

Decide which ones actually need global scope, instead of GPIO or TIM initializations which occur once.

Use 'extern' in secondary use cases.
