Documentation of serial protocol

[br101]

Is there a documentation of the serial protocol, apart from HowToParsePointCloudAndIMUDataFromMavLinkMessages.md?
There are obviously more commands to configure/start/stop the hardware.

I want to use the L1 on a platform different from the provided precompiled libraries aarch64 and x86_64... in the best case is there a possibility to access the source code of libunitree_lidar_sdk.a?

I was wondering the same thing for the L2 model.
A protocol description, a Windows library or just the source code for the library so we can integrate it ourselves would be appreciated.
There is a Windows test program they have now, so there should be ways to get it to other platforms.
