Add custom devboard - Databoard

[its-kronos]

Summary

This PR fixes/implements the following bugs/features

• Add custom devboard Databoard - Github Repo

Explain the motivation for making this change. What existing problem does the pull request solve?

Since it's a custom board, it has slightly different configuration compared to the generic (16 MHZ crystal instead of 8 MHZ), which means the exported binary from arduino with generic board doesn't work to establish serial communication

Validation

• Ensure CI build is passed.
• Demonstrate the code is solid. [e.g. Provide a sketch]

Code formatting

• Ensure AStyle check is passed thanks CI

Closing issues

Fixes #xxx

If there is a way to have custom pin namings, please let me know, the guide for adding a board isn't really clear on this

[its-kronos]

also, is there a way I can test the code generated by stm32cubemx before the board gets into the offical

You can create alias in the variant_DATABOARD.h like this:

#define My_CUSTOM_NAME PYn

#define IO1              PA10
#define AIO10              PA5

also, is there a way I can test the code generated by stm32cubemx before the board gets into the offical

Before it gets merged?
Well if you used the git repo instead of the package you could test it with Arduino IDE.

need to test with arduino ide using repo before making PR ready for review

After following the instructions in the using git repo, and successfully cloning with my board in the variants folder, I do not see an option to select it in Arduino IDE

Hi @its-kronos

I fetch your PR and see the "databoard" in the menu.
You could try to made a "Reload Board Data" in the tools menu.
If it does not work after a restart, you could try to delete cache:
