polypacket 1.0.72

A tool for building protocol services

Poly Packet is a set of tools aimed at generating protocols from embedded projects. Protocols are described in an YAML document which can be easily shared with all components of a system.

A python script is used to parse the YAML file and generate C/C++ code as well as documentation. The code generation tool can create the back end service, application layer, and even an entire linux utility app

Installation

The tools can be installed using pip:

pip3 install polypacket

To view an example protocol file:

poly-make -e

Live Protocol Interpreter

Once you have a descriptor file, you can run a live interface of the protocol using poly-packet

Open two terminals and connect them over udp to test it out:

terminal 1:

poly-packet -i sample_protocol.yml -c connect udp:8020

terminal 2:

poly-packet -i sample_protocol.yml -c connect udp:8010:8020

The terminal interface uses autocompletion, so hit tab to show available packet/ field types. to send a packet just type the packet name followed by comma seperated field names and values.

example:

Data sensorA: 45, sensorB: 78, sensorName: mySensor
