47 * \section SSec_Description Project Description:
48 *
49 * This bootloader enumerates to the host as a HID Class device, allowing for Teensy compatible programming
50 * software to load firmware onto the AVR, such as the official software at <a>http://www.pjrc.com/teensy/</a>.
51 *
52 * Out of the box this bootloader builds for the ATMEGA32U4, and will fit into 2-4KB of bootloader space. For other
53 * devices, the makefile will need to be updated to reflect the altered MCU model and bootloader start address. When
54 * calculating the bootloader start address, use (TARGET_FLASH_SIZE_BYTES - 4096) for targets where the bootloader
55 * compiles larger than 2KB, or (TARGET_FLASH_SIZE_BYTES - 2048) for smaller targets where the bootloader compiles
56 * under 2KB.
57 *
58 * This spoofs (with permission) the official Teensy bootloader's VID and PID, so that the software remains
59 * compatible with no changes.
60 *
