Hello friends, I hope you all are doing great. Today, I am going to share the Arduino GIGA R1 WiFi Library for Proteus . The GIGA R1 WiFi is the biggest board Arduino makes today: the Mega's familiar shape and headers, but with a dual-core STM32H747 inside - a Cortex-M7 and a Cortex-M4 on one chip - plus Wi-Fi, 8 MB of SDRAM and a pile of connectors. With this library your GIGA sketches run in Proteus 8.5, and not just one of them: the M7 core runs your main sketch while the M4 core runs a second one, and the two talk to each other through RPC , exactly as on the real board.
