Arduino Ecosystem
OpenHW Studio's ability to seamlessly compile and run code originally meant for physical hardware is built heavily around the standards established by the Arduino ecosystem.
Arduino Core & Libraries
LGPL / GPL The Arduino core software provides the foundational API (like `digitalWrite`, `Serial.print`, etc.) that simplifies microcontroller programming.
Usage in OpenHW Studio: We utilize compiled versions of the Arduino Core (for AVR and RP2040) so that user-written sketches run exactly as they would on physical Arduino boards. Furthermore, the studio integrates with popular open-source Arduino libraries to interface with sensors and displays.
