boot2duino serves no other purpose than to generate a bootable x86 floppy image using the Arduino IDE, which seemingly serves no purpose.

Watch it in action: writing a hello world; a very basic piano.

Video vid; void setup() { vid.print("Hello world, from Arduino!"); } void loop() { }

Other examples:

• keyboard interaction
• piano

Linux :

mkdir -p ~/Arduino/hardware/boot2duino cd ~/Arduino/hardware/boot2duino git clone https://github.com/jeanthom/boot2duino

Windows :

mkdir %UserProfile%\Documents\Arduino\hardware cd %UserProfile%\Documents\Arduino\hardware git clone https://github.com/jeanthom/boot2duino

Using qemu:

qemu-system-x86_64 -drive file=boot2duino-demo.ino.x86-pc.img,index=0,if=floppy,format=raw -soundhw pcspk

1. Install an x86 compiler
2. Try upgrading your Arduino IDE
3. Windows is not very well supported, give Linux a try
4. Upgrade GCC to 11 (see this issue and this)
