Arduino IDE vs Eclipse 4diac

Arduino IDE is a free desktop environment for building projects with electronic devices that interact with the physical world. The software page lists version 2.3.10, with downloads for Windows, macOS, and Linux. Its editor provides autocompletion, code navigation, and a live debugger; documentation also covers debugging, the Serial Monitor, and the Serial Plotter. Arduino CLI offers a text-based environment to build, compile, and upload sketches, and manage libraries and boards. Documentation describes synchronizing sketches between IDE 2 and Arduino Cloud through a Remote Sketchbook. Arduino IDE 2.0 is open source, with source code hosted on GitHub. Listed targets include Arduino AVR, megaAVR, SAMD, SAM, Mbed OS Nano, and Mbed OS Portenta. Nightly builds preview incoming releases with updated features and bug fixes. Arduino describes its ecosystem as serving students, makers, and professional developers. The software page states that downloads are provided as is and disclaims express and implied warranties.

Eclipse 4diac is free software for developing with IEC 61499 function blocks and C++. It runs on Linux, macOS, and Windows and includes firmware debugging. The environment supports protocols including OPC UA, OPC DA, HTTP, MQTT, RS232 serial, FMI, TSN, FBDK/IP, Modbus, openPOWERLINK, and Arrowhead. Listed boards include Raspberry Pi, BeagleBone Black, PLC01A1, Revolution Pi, Wago PFC200, PiFace Digital 2, µMIC.200, Bosch Rexroth PLC, and Lego Mindstorms EV3. Deployment targets include Windows and Linux, including ARM systems, plus NetOS, eCos, rcX, vxWorks, and freeRTOS. The deployment scope also names PLCs and embedded devices. This gives developers a free environment with named language support, communication protocols, hardware options, and runtime targets. Desktop use spans the three listed operating systems, while deployment options extend into embedded and industrial environments. Eclipse 4diac is available from the project website at eclipse.dev/4diac.
