Project description

Overview Honorat GBEDAGBE is a GitHub maker with public C firmware repositories, including this STM32 datalogger and a gesture-control robotic arm project. This repository defines an intelligent industrial datalogger concept for predictive maintenance, using an STM32F407VET6 as the controller and a WIZnet W5500 as the intended wired Ethernet interface for Modbus TCP and a small web interface. The important reading is that this is an early STM32CubeIDE scaffold, not a finished industrial firmware release. The README describes a multi-physics maintenance node for pumps, motors, compressors…
