Uses embedded-hal 1.0.0 traits (SpiDevice) and patterns from Eldruin's driver-examples
Communication with MAX31856 only works with Spi Mode 1 or 3.
Features:
- Modify default configuration. See:
config() - Read/write configuration. See:
send_config() - Read Linearized thermocouple temperature in Celcius. See:
temperature() - Read cold junction temperature. See:
cold_junction_temperature() - Read Fault status. See:
fault_status()
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.
use max31856;
fn example<S, FP>(spi_dev: S, fault_pin: FP) -> Result<(), max31856::Error>
where
S: embedded_hal::spi::SpiDevice,
FP: embedded_hal::digital::InputPin,
{
let mut sensor = max31856::Max31856::new(spi_dev, fault_pin);
// A default configuration is set on creation. It can be edited as follows
sensor.config().average_samples(max31856::AveragingMode::FourSamples);
let _ = sensor.send_config();
println!("Temperature: {}", sensor.temperature().unwrap());
sensor.config().conversion_mode(max31856::CMode::AutomaticConversion);
let _ = sensor.send_config();
println!("Temperature: {}", sensor.temperature().unwrap());
// Faults can be assessed via
println!("Status: {:?}", sensor.fault_status());
Ok(())
