Bindings for RaspberryPi's vcgencmd utility

The vcgencmd crate provides a way to interact with the vcgencmd utility included in Raspbian through a Rust program.

As of yet, not all vcgencmd commands have a binding. To see which commands are missing, take a look at PROGRESS.md in the projects repo. I will only actively add bindings for commands if I happen to need them personally. If you need a specific command that's unimplemented, feel free to open an issue asking for it or submit a pull request with the implementation yourself.

Installation

Install from Crates.io:

[dependencies]
vcgencmd = "0.3.*"

Features

• serde: Serialization and de-serialization for the few data structures this crate contains are supported via the serde feature flag:

[dependencies]
vcgencmd = {version: "0.3.*", features = ["serde"]}

Quick Start

use vcgencmd::{measure_temp, get_throttle, ThrottledStatus};

// You'll want to import the `Src` enum, which holds all available sources
// for the different commands
use vcgendcmd::Src;

// Gives the current temperature as f64 in °C
let temp = measure_temp().unwrap();

// Measure the arm chips memory usage
let arm_mem = get_mem(Src::Mem(MemSrc::Arm)).unwrap();

// Measure the voltage at the video core
let volt_gpu = measure_volts(Src::Volt(VoltSrc::Core)).unwrap();

// Get a bit pattern which represents the throttled state of the system
let bit_pattern = get_throttle.unwrap();

// Get comprehensive, human readable info about the throttled state of the system
let throttle_status = ThrottledStatus::new(&bit_pattern);

// If you've enabled the `serde` feature, you can serialize/deserialize the crates datastructures
use serde_json::to_string;
let serialized = to_string(&throttle_status).unwrap();
