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.
Install from Crates.io:
toml
[dependencies]
vcgencmd = "0.3.*"
serde: Serialization and de-serialization for the few data structures this crate contains are supported via the serde feature flag:toml
[dependencies]
vcgencmd = {version: "0.3.*", features = ["serde"]}
```rust use vcgencmd::{measuretemp, getthrottle, 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 armmem = getmem(Src::Mem(MemSrc::Arm)).unwrap();
// Measure the voltage at the video core let voltgpu = measurevolts(Src::Volt(VoltSrc::Core)).unwrap();
// Get a bit pattern which represents the throttled state of the system let bitpattern = getthrottle.unwrap();
// Get comprehensive, human readable info about the throttled state of the system let throttlestatus = ThrottledStatus::new(&bitpattern);
// If you've enabled the serde feature, you can serialize/deserialize the crates datastructures
use serdejson::tostring;
let serialized = tostring(&throttlestatus).unwrap();
```
