dmrgo

This library decodes a raw 33-byte DMR packet into Golang-native structures.

Usage

A complete example can be found at examples/benchmark.go

The full definitions of EXAMPLE_DMR_PARROT_KERCHUNK_BURSTS and EXAMPLE_DMR_SMS_BURSTS are excluded for brevity.

const (
    DMR_BURST_SIZE = 33

    DMR_PARROT_KERCHUNK_BURST_COUNT = 15
    DMR_SMS_BURST_COUNT             = 8
)

var EXAMPLE_DMR_PARROT_KERCHUNK_BURSTS = [DMR_PARROT_KERCHUNK_BURST_COUNT][DMR_BURST_SIZE]byte{
    {68, 75, 3, 135, 36, 66, 12, 240, 21, 240, 12, 161, 196, 109, 255, 87, 215, 93, 245, 222, 49, 168, 53, 24, 63, 48, 61, 97, 56, 82, 151, 134, 91},           // First, burst
    ...
}

        fmt.Printf("Took %s to decode burst\n", timeElapsed)
    }

    fmt.Println("---------------------------------")
