cp211x_uart

Documentation License: MIT Build Status

HID-to-UART driver for CP2110/CP2114 chipset. It is wrapper around hid::Handle intrinsically.

See documentation for details.

Building

Linux

$ sudo apt-get install libudev-dev libhidapi-dev $ cargo build

Usage

``` rust extern crate hid; extern crate cp211x_uart;

use std::time::Duration; use cp211x_uart::{HidUart, UartConfig, DataBits, StopBits, Parity, FlowControl};

fn run() -> Result<(), cp211x_uart::Error> { let manager = hid::init()?; for device in manager.find(Some(0x10C4), Some(0xEA80)) { let handle = device.open()?; let mut uart = HidUart::new(handle)?;

    let config = UartConfig {
        baud_rate: 9600,
        data_bits: DataBits::Bits8,
        stop_bits: StopBits::Short,
        parity: Parity::None,
        flow_control: FlowControl::None,
    };

    uart.set_config(&config)?;
    uart.set_read_timeout(Duration::from_millis(50));
    uart.set_write_timeout(Duration::from_millis(500));
    uart.flush_fifos(true, true)?;

    uart.write(&[0x01, 0x02, 0x03][..])?;
    let mut buf: [u8; 256] = [0; 256];
    uart.read(&mut buf)?;
}

}

fn main() { match run() { Ok() => {} Err(err) => { eprintln!("ERROR: {}", err); } } } ```
