MightyCore v2.1.0

Changelog:

• Fix missing parenthesis in the round() macro that caused it to return incorrect results
• Revert abs() macro to use the "standard" Arduino implementation rather than being a wrapper for __builtin_abs()
  • Apparently, __builtin_abs() doesn't handle floats
• Improve timing accuracy for all supported clock frequencies. Huge thanks to @cburstedde!
• Add MPLAB SNAP and PICkit4 programmers

MightyCore v2.0.8

Changelog:

• Fix typo in round() and constrain() macros (#199)

MightyCore v2.0.7

Changelog:

• Fix export compiled binary for Windows computers
• Remove bundled Ethernet library
  • The one that ships with Arduino IDE are compatible and up to date
• Improve "unsafe" macros
  • This includes abs(), min(), max(), sq(), round() and constrain()

MightyCore v2.0.6

Changelog:

• Implement PROGMEM1
  • Great if you want to store data in the upper part in the ATmega1284/P flash memory
• Fix issue where 1 MHz compiled bootloaders ran at 8 MHz
  • This bug affected ATmega164, ATmega324, ATmega644 and ATmega1284
• Load user application and bootloader when uploading using programmer and a bootloader option is selected.
  • If you want to wipe the bootloader, simply choose "No bootloader"
• Generate assembly output when exporting binaries
• Add EEPROM retain menu option
  • Only applies when uploading using a programmer or burning bootloader
• Wire and Wire1 is now based on the same class (TwoWire), so Wire1 can be passed to any library that expects a TwoWire object
  • Big thanks to @asukiaaa for doing all the hard work
• Update Arduino core files
  • Replace sbi and cbi macros with "regular" bitshifts for reduced compiled size and improved execution speed

MightyCore v2.0.5

Changelog:

• Add PIN macros
  • You can now refer to pins as PIN_PB0
• Add 4 MHz, 2 MHz and 1 MHz internal and external oscillator
• Update corefiles

MightyCore v2.0.4

Changelog:

• Fix bootloader LED for Bobuino pinout (#157)
  • Bootloader LED is now PB7 instead of PB0
• Fix a bug in the Wire library that may cause slave functionality to malfunction
• Add missing INTERNAL2V56 definition for ATmega324PB (#169)
• Add 115200 baud bootloader for 12 MHz clock (#167)
• Remove flush() from stream class (#173)
• Add slow USBtinyISP and USBasp programmers

MightyCore v2.0.3

This release is a maintenance release that fixes some PlatformIO related issues.

Changelog:

• Fix PlatformIO issue where automatic including of SPI1.h caused compilation to fail for all other targets than ATmega324PB
• Fix old SD card initialization bug
• Add 22.1184 MHz bootloader

MightyCore v2.0.2

Changelog:

• Fix wrong CFD fuse bit for ATmega324PB
• Add printf to print class
• Fix compiler warnings caused by EEPROM library
• Add slow USBasp programming option (useful when working with a 1 MHz clock)
• Add dedicated bootloader option menu menu
  • You can now choose if you want to use UART0 or UART1 for uploading.
  • You can also choose to not use a bootloader at all
• Better support for PlatformIO
• Add 14.7476MHz, 11.0592MHz, 7.3728MHz, 3.6864MHz and 1.8432 MHz clock option

MightyCore v2.0.1

Changelog:

• ATmega324PB now supported
• Lots of new pre-compiled bootloaders added
  • The makeall build script have been improved, so it's now much easier change build options
• Minor documentation improvements

MightyCore v2.0.0

It's finally here, the next MightyCore release!

Changelog:

• Fix duplicate file issue with SPI library
• Arduino corefiles and bootloader moved to separate repos for easier maintenance
• Add support for Atmel ICE, JTAGICE3 and Arduino.org programmers
• SoftwareSerial library can now make use of "regular" interrupt pins
  • This means ATmega16/32/8535 can use INT0, INT1 or INT2 to receive data
• Get rid of library related warnings
• Add Sanguino pinout
  • Used by some 3D printer boards
• Update Ethernet library
• Improved documentation
