Crate max31856

Rust driver for MAX31856

Uses embedded-hal traits and patterns from Eldruin's driver-examples

Features:

• Modify default configuration. see config()
• Read/write configuration. See: send_config()
• Read Linearized thermocouple temperature in Celcius. See: temperature()

Features in the next few versions:

• Interrupts with FAULT pin
• External temperature sensor for cold junction conversion
• Read/write fault mask registers.
• Read/write cold junction fault mask registers.
• Read/write Linearized temperature fault registers.
• Read/write cold junction temperature offset registers.
• Read cold junction temperature.
• Read Fault status.

Usage example

extern crate max31856
extern crate linux_embedded_hal
 
let spi = Spidev::open("/dev/spidev0.0").unwrap();
let cs = Pin::new(25);
let fault = Pin::new(23); //Fault pin is unused
let mut sensor = Max31856::new(spi, cs, fault);
// A default configuration is set on creation. It can be edited as follows
sensor.config().average_samples(max31856::AveragingMode::FourSamples);
sensor.send_config();
println!(sensor.temperature().unwrap());
sensor.config().conversion_mode(max31856::CMode::AutomaticConversion);
sensor.send_config();
println!(sensor.temperature().unwrap());
