Scanning HibouAir Sensors with CircuitPython, BleuIO and the Cytron MOTION 2350 Pro

Scanning HibouAir Sensors with CircuitPython, BleuIO and the Cytron MOTION 2350 Pro

In this tutorial we will use CircuitPython to turn a Cytron MOTION 2350 Pro into a HibouAir scanner. The board’s RP2350 has no Bluetooth radio of its own. A BleuIO dongle in the board’s USB-A host port provides Bluetooth Low Energy, and a short CircuitPython program talks to it with ordinary AT commands.

Building a Modbus RTU Client with STM32 and RS-485

Building a Modbus RTU Client with STM32 and RS-485

This project demonstrates how to build a Modbus RTU client using an STM32 microcontroller and an RS-485 transceiver. The STM32 communicates with a Modbus server over a two-wire, half-duplex RS-485 bus to read two holding registers using Function Code 0x03.
