Function robust_arduino_serial::read_i16

pub fn read_i16<T: Read>(file: &mut T) -> Result<i16, Error>

Read two bytes from a file/serial port and convert it to a 16 bits int

Example

use std::io::Cursor;
use std::io::SeekFrom;
use std::io::prelude::*;
use robust_arduino_serial::*;

let mut buffer = Cursor::new(Vec::new());
let number: i16 = -355;

// Write the number to the buffer
write_i16(&mut buffer, number).unwrap();

// Go to the beginning of the buffer
buffer.seek(SeekFrom::Start(0)).unwrap();

// Read 16 bits (two bytes) from the buffer
let read_number: i16 = robust_arduino_serial::read_i16(&mut buffer).unwrap();

assert_eq!(read_number, number);
