vserialx

vserialx is a tiny library for serial communication in Linux using V.

Usage

module main

import time
import vserialx as vs

fn main() {
    mut dev := vs.new('/dev/ttyS20', .b9600, .@none, .@none, .one, .char8b)

    mut rc := dev.open()

    if rc != .okay {
        println('Failed to open.\nERROR: ${rc}')
        return
    }
    defer {
        dev.close()
    }

    rc = dev.open()
    if rc != .okay {
        println('Failed to connect.\nERROR: ${rc}')
        return
    }

    for {
        if dev.available_bytes() > 0 {
            len, buff, rt := dev.read(10)
            dump(rt)
            if len > 0 {
                println('BUFF: {${buff.hex()}}')
            }
        }
        time.sleep(time.second)
    }
}

TODO features

• Exclusive access (locking and unlocking mechanism).
• Reading configurations using tcgetattr and ioctl . Read only the baudrate for now.
• Better error/return code naming
• The documentation

TODO testings

• Other serial port configurations need to be tested.
• Bloking read/write need to be tested.
