serial.nim

A library to work with serial ports using pure Nim.

Installation

serial can be installed using Nimble:

nimble install serial

Or add the following to your .nimble file:

# Dependencies

requires "serial >= 1.0.0"

Usage

There are some examples in the examples directory, showing reading from and writing to a serialport.

Listing serial ports

import serial # Or: `import serial/utils`

for port in listSerialPorts():
  echo port

Reading from/writing to a serial port (echoing data)

import serial # Or: `import serial/serialport`

let port = newSerialPort("COM1")
# use 9600bps, no parity, 8 data bits and 1 stop bit
port.open(9600, Parity.None, 8, StopBits.One)

# You can modify the baud rate, parity, databits, etc. after opening the port
port.baudRate = 2400

var receiveBuffer = newString(1024)
while true:
  let numReceived = port.read(receiveBuffer)
  discard port.write(receiveBuffer[0 ..< numReceived])

Using the SerialStream

import serial # Or: `import serial/serialstream`

let port = newSerialStream("COM1", 9600, Parity.None, 8, StopBits.One, buffered=true)

while true:
  # Read a line from the serial port then write it back.
  port.writeLine(port.readLine())
