Atmega32U4 support

[eadmaster]

Atmega32U4 is another popular (older) alternative to the STM32F1

This should be possible, but someone needs to actually write the code :stuck_out_tongue:. Over the next few weeks I'll be working on the documentation, so that newcomers can easily understand the project structure and how to add support for new targets and platforms.

It's too diffcult to understand.XD I don't know how to use those code. it should be easy understand, just like load the target on KEIL and VSC.

Yes, because the firmware has many different targets, from different vendors. The protocol code is shared, and each platform/target must implement a few HALs. I will work on documentation explain exactly how it works and how to get started.

FYI, I have added a bit of documentation, but it's still a bit scarce.

• Code structure
• Porting checklist
• HALs definition

Also some overall guidelines for contributing.
