// Notes:
// This file adds support for the Micronucleus bootloader V1 and V2,
// so you do no longer need the Micronucleus command-line utility.
//
// This bootloader is typically used on small ATtiny boards,
// such as Digispark (ATtiny85), Digispark Pro (ATtiny167),
// and the respective clones.
// By default, it bootloader uses the VID/PID 16d0:0753 (MCS Digistump).
//
// As the micronucleus bootloader is optimized for size, it implements
// writing to flash memory only. Since it does not support reading,
// use the -V option to prevent avrdude from verifing the flash memory.
// To have avrdude wait for the device to be connected, use the
// extended option '-x wait'.
//
// Example:
// avrdude -c micronucleus -p t85 -x wait -V -U flash:w:main.hex
