About:
bootloadhid is a firmware-only USB bootloader for AVR microcontrollers that utilizes the V-USB library to implement a low-speed USB device. It allows users to program AVR chips via a standard USB connection without requiring a dedicated USB hardware interface. This tool is particularly valuable for embedded developers creating custom devices with USB connectivity.
Key Features:
  • Firmware-only implementation requiring no special USB hardware
  • HID-based communication compatible with standard USB drivers
  • Supports multiple AVR microcontroller families
  • Small memory footprint suitable for resource-constrained devices
Use Cases:
  • Programming custom AVR-based USB devices in development
  • Updating firmware on field-deployed embedded systems
  • Creating USB-enabled projects without dedicated USB ICs
Alternatives:
  • avrdude – Standard AVR programmer that supports various hardware interfaces but requires dedicated programmers
  • dfu-programmer – Device Firmware Upgrade tool for Atmel AVR chips with built-in DFU bootloader
