Support for H755ZI

[Stelath]

Is your feature request/improvement related to a problem? Please describe.

Hi, I work with a team of University students working on rocketry and we cant use our H755ZI boards with Arduino core because it isn't supported, and would love if y'all could add support.

Describe the solution you'd like

Addition of the H755ZI Processor to the STM32 Arduino Core

Describe alternatives you've considered

Purchasing H753ZI boards that are supported, but we already have around 20 H755ZI Boards

Hi @Stelath
I guess you ask support of the https://www.st.com/en/evaluation-tools/nucleo-h755zi-q.html ?
Did you evaluate to add them yourself? It is a community project any help are welcome.
Added to #722

I'm not entirely sure how to but I'll give it a shot, if there any instructions outlining what to do? or should I just look at what other commits have done?

I close it as it is added to #722.

How do I generate the variant_NUCLEO_STM32H755ZI.h and .cpp files? I've done the rest with the generic processor

You have to create them manually.

Any tips on where to find most of the info? Or do I just have to look at pinouts?

[fpistm]

Most of the info of the board are in the user manual: https://www.st.com/resource/en/user_manual/um2408-stm32h7-nucleo144-boards-mb1363-stmicroelectronics.pdf

Else yes most of the work is to do proper pin mappings and define all dedicated pins (LED, button, default Serial instance, ...) and add a clock config probabmy using the HSE.
