What is this

This libary converts a byte stream (chan byte) into structs for parsing messages over MBus for the Advanced Metering System (AMS), also known as a Smart meter for measuring power consumption.

Usage

func main() {
	byteStream := getByteChannel() // byteStream is a `chan byte`, read more below
	next := ams.ByteReader(byteStream)
	for {
		bytePackage, _ := next()
		message, _ := ams.BytesParser(bytePackage)
		fmt.Printf("%+v\n", message)
	}
}

byteStream is a chan byte from the serial port, you need to create this yourself a good example can be found here: https://github.com/karl-gustav/ams-han-cmd/blob/master/main.go

With error handlin:

func main() {
	byteStream := byteChannel()
	next := ams.ByteReader(byteStream)
	for {
		bytePackage, err := next()
		if err != nil {
			fmt.Println(err)
			if err == ams.CHANNEL_IS_CLOSED_ERROR {
				return
			}
			continue
		}

		message, err := ams.BytesParser(bytePackage)
		if err != nil {
			fmt.Println(err)
			continue
		}
		fmt.Printf("%+v\n", message)
	}
}

Helper function to make printing []byte easier:

func byteArrayToHexStringArray(bytes []byte) (strings []string) {
    for _, b := range bytes {
        strings = append(strings, fmt.Sprintf("0x%02x", b))
    }
    return
}
