MicroCore v2.3.0
Changelog:
- Fix the issue where the AVRISPmkII programmer option didn't work
- Add operator bool to
Serial
for compatibility with the official Arduino API (#145) - Add support for the Urboot bootloader
- The bootloader occupies 256 bytes of flash, which leaves 256 bytes for the user application
- The bootloader uses the Urprotocol, which is designed to be tightly integrated with Avrdude
- The bootloader is very rugged and reliable, and will not loose its patched reset vector like Optiboot on ATtinys can
