serialport_low_latency

FTDI 串行通信芯片支持低延迟模式，其中延迟计时器降低到 1 毫秒。此包允许通过 TIOCSSERIAL ioctl 在 Linux 上启用和禁用此低延迟模式。

示例

打开串口并启用低延迟模式

use std::time::Duration;
use serialport_low_latency::enable_low_latency;
let mut port = serialport::new("/dev/ttyUSB0", 115_200)
    .timeout(Duration::from_millis(10))
    .open_native().expect("Failed to open port");
enable_low_latency(&mut port).unwrap();

打开串口并禁用低延迟模式

use std::time::Duration;
use serialport_low_latency::disable_low_latency;
let mut port = serialport::new("/dev/ttyUSB0", 115_200)
    .timeout(Duration::from_millis(10))
    .open_native().expect("Failed to open port");
disable_low_latency(&mut port).unwrap();
