busylight VS pySerial

I'm trying to compile a slight change in the code for https://github.com/buildcomics/busylight

Code your REST endpoint to use something like pySerial to send the message to your device

If the Tach is the older style I think this would be a great first project. If you need to emulate CAN it’s going to be a rather more complex project. python CPU/RAM utilizationpython Serial communication library

I haven't, but I would try a Linux box with two serial ports, connect both things to it so it's literally man in the middle. The PySerial module for Python, and it has an example bi-directional Serial to TCP/IP relay including a threaded serial listener, you might be able to hack that into a Serial <--> Serial relay with custom logging/interception fairly quickly.

Connecting to the Russound device is only possible by TCP, you can make use of a TCP to Serial gateway such as tcp_serial_redirect

Look in source https://github.com/pyserial/pyserial/blob/master/serial/serialcli.py

# Download pyserial to ~/ cd ~/ wget https://github.com/pyserial/pyserial/archive/refs/tags/v3.4.tar.gz -O pyserial-3.4.tar.gz # Create a temp dir to do the work in export tmp_dir=~/install_temp/ mkdir $tmp_dir cd $tmp_dir # Extract and install pyserial tar -xvf ~/pyserial*.tar.gz cd pyserial* python setup.py install --user # Clean-up cd ~/ rm $tmp_dir/ -Rf

The code that runs on the Raspberry Pi needs to listen for incoming data over the serial connection. Several libraries exist, we will choose the Python library pyserial.

Try pyserial
