Quick start
From an unopened box to a script running on a host, H1 takes six steps.
Plug H1 into a USB-A port on your computer
That is the only connection it needs — the port supplies both power and data.
Boot into Attack Mode (the default)
Just plug it in normally. Don’t touch the Upload button.
Or boot into Upload Mode
Hold down the Upload button — the one closest to the STM32 chip — while plugging the device in, then release it once it’s connected.
Upload a script
In Upload Mode, H1 enumerates as a USB CDC (serial) device. Open the HiveFusion Lab IDE, write or open a script, and hit Upload — the IDE compiles your script to bytecode and writes it to the device’s onboard flash.
Run it
Unplug H1 and plug it back in without holding the Upload button. It boots into Attack Mode and runs the script you just uploaded.
Restart without unplugging
Press the Reset button at any time to restart the device in place. It re-checks the button state and picks a mode again.
The Upload button is read once, at power-on. Pressing it after the device has already started does not change the mode — see Boot modes.
