Overview

Simple project that exposes different executables which are able to send the string "e" through the serial port /dev/ttyUSB0 and print the response.

It was mainly used to test the communication with the microcontroller (in an Arduino Nano board) in the Andino robot. The string "e" is parsed by the microcontroller, which reads the two wheel encoders and send the values back via serial port. The Andino project itself contains a more involved demo application to test this behaviour which uses the LibSerial library.

Although the example uses the Andino project as a reference, the code present in this project can be used to send any other types of messages via serial port if adapted.

Project creation

Steps used to create this project using Pixi version 0.53.0.

• pixi init cpp_serial
• pixi add cmake boost_asio
• pixi add --feature build cxx-compiler ninja
• pixi workspace environment add build
• pixi workspace environment add build --feature build --solve-group default

Then the tasks sections (tasks.start, feature.build.tasks.configure and feature.build.tasks.build) were added manually, directly in the pixi.toml file.

Followed the example structure for the cpp-sdl example project.

Setup

Navigate to the project root directory and run:

• pixi install

Usage

Configure the CMake project

• pixi run configure

Build the executable

• pixi run build

Start the build executable

There are 2 versions, all of them have the same logic but use different libraries/approaches:

• Using Termios: pixi run start_termios
• Using Boost.Asio: pixi run start_boost
