Serial communication

Example code how to transfer data over serial communication on Linux, both read and write.

Install:

sudo apt install socat
pip install pyserial
pip install pyserial-asyncio

How to compile C++:

# All
make

# Single file
g++ -o <output file name> <file to compile>.cpp

How to run Rust:

cd rust
cargo run --bin <file to run>

How to run:

All programs accept the serial port path as a command-line argument.

Automated Testing

You can run a full cross-test of all C++, Rust, and Python implementations using the provided script:

python3 test_all.py

This script will set up virtual ports using socat and verify communication across all reader/writer combinations (ensure C++ programs are compiled first).

Manual Running:

1. Create bidirectional socket cable communication:

socat -d -d pty,raw,echo=0 pty,raw,echo=0

It will create 2 addresses (e.g., /dev/pts/12 and /dev/pts/13).

2. Run a reader:

# C++
./cpp/read_sync /dev/pts/12

# Python
python3 python/read.py /dev/pts/12

# Rust
cd rust
cargo run --bin read_sync -- /dev/pts/12

3. Run a writer:

# C++
./cpp/write_sync /dev/pts/13

# Python
python3 python/write.py /dev/pts/13

# Rust
cd rust
cargo run --bin write_sync -- /dev/pts/13
