MCUHex

MCUHex enables flashing firmware (.bin or .hex) and live monitoring of variables on STM32 microcontrollers using a web browser. It requires installing a small tray app to bridge the browser and the debug probe (ST-Link, J-Link, DAPLink) and supports ARM Cortex-M devices (e.g., Nucleo and Discovery boards). It eliminates the need for IDE and toolchain setup, providing live variable monitoring, firmware flashing, and future plans for source-level debugging and collaborative workspaces.
