vcgencmd provides a way to interact with the vcgencmd utility included in Raspbian.
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. If you need a specific command that's unimplemented, feel free to open an issue asking for it or submit it yourself.
Install from Crates.io:
toml
[dependencies]
vcgencmd = "0.2.*"
Serialization and deserialization for the few structs this crate contains are supported via a serde_support feature flag:
toml
[dependencies]
vcgencmd = {version: "0.2.*", features = ["serde_support"]}
```rust // Import the various commands you want to use use vcgencmd::{measuretemp, getthrottle, interpretbitpattern};
// You'll also 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 = interpretbitpattern(bitpattern); ```
