Hello, I need to make packet’s in Matlab for ardupilot on MAVlink 2 protocol, how to calculate CRC and CRC_Extra for this packet’s? Where I can see documentation and examples for this?

Have you looked at the source code

github.com/ArduPilot/pymavlink

generator/C/include_v2.0/checksum.h

4960d4d20

#pragma once

#if defined(MAVLINK_USE_CXX_NAMESPACE)
namespace mavlink {
#elif defined(__cplusplus)
extern "C" {
#endif

// Visual Studio versions before 2010 don't have stdint.h, so we just error out.
#if (defined _MSC_VER) && (_MSC_VER < 1600)
#error "The C-MAVLink implementation requires Visual Studio 2010 or greater"
#endif

#include <stdint.h>

/**
