The Python script convert.py can be used to convert infrared serial interface commands (in hexadecimal representation) into a Flipper Zero[1] compatible infrared[2] .ir file.
The script supports sending multiple multibyte messages at once and adds wait times for message replies by default.
Use case: It can be used to convert LEGO MINDSTORMS RCX[3] (the "yellow programmable brick") infrared commands[4] (see LEGO_RCX.json input file).
⚠️ If LEGO MINDSTORMS RCX is a use case for you: the example does not take care of the toggle bit. So sending the IR commands may not always work. You'll need to dive deeper into the internals of the RCX communication protocol. Pull requests are very welcome!

A Python 3 environment is required.
The script only imports sys and json and therefore shouldn't require any additional packages.
Run converter and print output on stdout:
$ python convert.py LEGO_RCX.json
Run converter and pipe output to IR output file:
$ python convert.py LEGO_RCX.json > LEGO_RCX.ir
Run converter and pipe output to both an IR output file and stdout:
$ python convert.py LEGO_RCX.json | tee LEGO_RCX.ir
For the format of the .json file, inspect LEGO_RCX.json example.
The IR signal plot script additionally requires the Python module matplotlib.
Usage: python3 plot_signal.py <IR_file_name> <IR_signal_name>
Example:
python plot_signal.py LEGO_RCX.ir ABC_STOP
Trying to open file 'LEGO_RCX.ir' and then to plot signal 'ABC_STOP'
Found signal:
Raw signal name: ABC_STOP
Raw signal data: 833 417 417 417 417 ...
