Presentation

This project aims to receive commands and pilot several stepper motors

Details

• Infrastructure and Hardware: LAN <-> Raspberry PI 3 <-> SERIAL USB <-> ARDUINO MEGA 2560 <-> LCD 12864/RAMPS 1.4 <-> N x NEMA 17 stepper motors

• Software and Design : MQTT client subscriber <-> PROTOBUF <-> PYTHON <-> C++ <-> U8g2/StepperDriver

This design allows a distributed environment. Motors are remotely piloted, no high-level logic here this repo only handle the communication protocol and sending appropriate commands to the motors. Blue LCD embarked with the robot and motors is showing debug informations.

Setup

$ cd protobuf
$ generate_files.sh
