Library for retrieving readings from Adafruit STEMMA Soil Sensor.
The implementation is based on the Adafruit CircuitPython Seesaw library.
The library is tested and used on a Raspberry Pi 3 B+ board, running Raspbian but uses interfaces
from embedded_hal
operations like sleep/delay and other system calls.
Example
pub fn main(interval_ms: u64) {
use stemma_soil_sensor::SoilSensor;
use linux_embedded_hal::Delay;
use embedded_hal::blocking::delay::DelayMs;
let delay = Delay {};
let mut sensor = SoilSensor::init(delay).unwrap();
loop {
let temp = sensor.get_temp().unwrap();
let cap = sensor.get_capacitance().unwrap();
println!("Temperature: {:.02}", temp);
println!("Capacitance: {}", cap);
let mut delay = Delay {};
delay.delay_ms(2000u32);
}
}
Using this library with other boards
Since this library relies on rppal for the I2C communication it won't work with other boards than the Raspberry Pi series boards as it is right now.
Requirements
This library should build on the following targets:
- armv7-unknown-linux-gnueabihf
- armv7-unknown-linux-musleabihf
- aarch64-unknown-linux-gnu
Additional notes
Please make a note of that the repository includes a .cargo/config
entry. This is excluded from
the crate package. If you use this library from the repository directly make sure to change this
(or remove it) so it doesn't cause problems for your build.
