Anyleaf
For use with the Anyleaf pH sensor
For use with embedded systems, and single-board computers.
Example for Rasperry Pi, or other Linux systems:
Cargo.toml
:
[package]
name = "anyleaf_linux_example"
version = "0.1.0"
authors = ["Anyleaf <david.alan.oconnor@gmail.com>"]
edition = "2018"
[dependencies]
embedded-hal = "^0.2.3"
linux-embedded-hal = "^0.3.0"
anyleaf = "^0.1.0"
main.rs
:
use embedded_hal::blocking::delay::DelayMs;
use linux_embedded_hal::{Delay, I2cdev};
use anyleaf::{PhSensor, CalPt, CalSlot};
fn main() {
let i2c = I2cdev::new("/dev/i2c-1").unwrap();
let mut ph_sensor = PhSensor::new(i2c);
ph_sensor.calibrate_all(
CalPt::new(0., 7., 25.), CalPt::new(-0.18, 4., 25.), Some(CalPt::new(0.18, 10., 25.))
);
let mut delay = Delay {};
loop {
let pH = ph_sensor.read().unwrap();
println!("pH: {}", pH);
delay.delay_ms(500_u16);
}
}
