Lua Serial Port

Introduction

This project implements a Serial Port module for Lua. It currently only supports Linux, and requires LuaJIT FFI.

Example

local sp = require "serial-port"
sp.open("/dev/ttyUSB0");
sp.setBaud(sp.B115200);
local count = sp.write("123");
print("Wrote " .. count .. " bytes");

Motivation

While the same could be accomplished using various projects like luaposix or librs232lua, many times you simply need something simple and don't want to be bothered with building extensions that have native code -- especially cross compiling for embedded platforms.

Status

• non-blocking read/write implemented
