byteorder is a Go module for working with arbitrarily-ordered byte slices.
It is useful e.g. when dealing with Modbus wire formats.
Installation:
go get github.com/andig/byteorder
Usage:
import "github.com/andig/byteorder"
// reverse byte order, i.e. little endian
bo := New("BA")
fmt.Printf("0x%04x", bo.Uint16([]byte{1, 2}))
// Output: 0x0201
NOTE: byteorder is not optimized for performance. The conversion functions will allocate which may not be desirable in high-frequency code paths.
In addition to the Go binary.ByteOrder implementation, this modules provides convenience functions for the ioBroker.modbus data types.
