MiniCore 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

MiniCore v2.0.9

Changelog:

• Fix typo in constrain() and round() that broke compilation for a lot of projects

MiniCore v2.0.8

Changelog:

• Fix export compiled binary for Windows computers
• Improve "unsafe" macros

• This includes abs(), min(), max(), sq(), round() and constrain()

MiniCore v2.0.7

Changelog:

• Update Wire and Wire1 library (#150)
  • 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 corefiles
  • Remove sbi and cbi macros, and use regular bitshifts instead for faster code execution and reduced compiled size

MiniCore v2.0.6

Changelog:

• Fix an issue where bootloaders compiled for 1 MHz was actually running at 8 MHz (#140)
• Load user application + bootloader when uploading using programmer
  • This means that the IDE won't wipe the bootloader anymore if you're uploading with a dedicated programmer and a bootloader is selected in the Tools menu
• Save assembly output when exporting compiled binary
• Update fallthrough statement in Wire libraries to prevent warning in avr-gcc < 7
• Add EEPROM retain menu

MiniCore v2.0.5

Changelog:

• Add more programmers
• Add PIN macros
  • You can now refer to pins with the macros such as PIN_PD0
• Add 4 and 2 MHz internal clock option
• Add 4, 2 and 1 MHz external clock option
• Update corefiles

MiniCore v2.0.4

Changelog:

• Add more supported clocks
  • 14.7456 MHz, 11.0592 MHz, 7.3728 MHz, 3.6864 MHz, and 1.8432 MHz added
• Fix A6 and A7 definitions for ATmega48/88/168/328PB (#107)
• Fix incorrect analogInputToDigitalPin macro
• Change baud rate for 8 MHz external option
  • Baud rate is now 57600 instead of 38400
  • This is to ensure compatibility across all my other Arduino cores
• Add 12 MHz 115200 baud bootloaders
• Fix issue where i2c slave functionality may not work (#122)
• Add slow USBtinyISP and USBasp programmers
  • Blank chips run at 1 MHz. Some programmers, especially USBasp are too fast for these chips.

MiniCore v2.0.3

Changelog:

• Fix issue where the 16 MHz option for ATmega8 didn't work (#88)
• Fix analogInputToDigitalPin for the standard pinout (#90)
• Fix digitalPinToPCICRbit for Atmega328PB (#91)
• Prepare for PlatformIO support

MiniCore v2.0.2

Changelog:

• Unify Wire+Wire1 and SPI+SPI1 library
• Fix CFD fuse bit for ATmega328PB
• Add printf to print class (Use Serial.printf for instance)
• Fix issue with PCINT macros not being correct
• Add wiring reference document
• Get rid of some compiler warnings related to the EEPROM library
• UART1 on ATmega328PB can now be used for serial upload

MiniCore v2.0.1

Changelog

• Fix incorrect bootloader memory address for ATmega88PB and ATmega168/P/PA/PB
• Add EEPROM library
• SoftwareSerial library updated and now occupies less flash
