[][src]Crate sensirion_i2c

Library with common functionality for I2C based sensors from Sensirion, based on the embedded-hal traits.

Usage

CRC8 calculation / validation

use sensirion_i2c::crc8;

let data = [0xbe, 0xef];
let crc = crc8::calculate(&data);

let data = [0xbe, 0xef, crc];
assert_eq!(Ok(()), crc8::validate(&data));

I2C

The I2C helpers work with any embedded_hal::i2c implementation.

use embedded_hal_mock::i2c::{Mock as I2cMock, Transaction as I2cTransaction};
use sensirion_i2c::i2c;

let expectations = [I2cTransaction::write(0x12, vec![0x34, 0x56])];
let mut i2c_mock = I2cMock::new(&expectations);
i2c::write_command(&mut i2c_mock, 0x12, 0x3456);
