# raspi-cpufreq

Minimal package to read ARM CPU frequency of the Raspberry Pi 4.

```go

import (

	"log"

	cpufreq "github.com/jig/raspi-cpufreq"

)

func main() {

	freq, err := cpufreq.Get()

	if err != nil {

		log.Fatal(err)

	}

	log.Printf("CPU frequency is %.1f GHz (range from %.1f GHz to %.1f GHz)", float64(freq)/1_000_000, float64(minFreq)/1_000_000, float64(maxFreq)/1_000_000)

}

```

# Command line

```bash

cd cmd/freq

go build

go install

freq

```

Example output:

```bash

2023/08/20 18:14:59 CPU frequency is 1.5 GHz (range from 0.6 GHz to 1.5 GHz)

```
