ina219
INA219 current/power monitor driver for Rust
Example
cargo build --example values --target=aarch64-unknown-linux-musl
cargo build --example raw_values --target=aarch64-unknown-linux-musl
cargo build --example physic_values --target=aarch64-unknown-linux-musl
support features
- ina219 feature contain physic
- physic
Add this line to Cargo.toml for full feature support
ina219_rs = { version = "0.5.0", features = ["ina219"] }

let opt = Opts::new(0x42,100 * physic::MilliOhm,1 * physic::Ampere);
//let opt = Opts::default();
let mut ina = INA219::new(device,opt);
ina.init().unwrap();
let pm = ina.sense().unwrap();
println!("{:?}",pm);
