Changelog:

  • Add upload bootloader speed menu option
    • Urboot has automatic baud rate detection, so the upload baud rate can be changed without flashing a new bootloader binary. The Default baud rate option should always work for the selected clock speed. However, faster or slower baud rates may be used if the baud rate error is within about ±2.5%. Use a baud rate calculator to check whenever a clock speed supports a particular baud rate.

Changelog:

  • Fix the TwoWire destructor to use the array delete operator (ATmega324PB)
  • Speed up 'available' function by inserting uint16_t (see arduino/ArduinoCore-avr#433 for details)
  • Prevent corruption of disassembler listing command for paths w/ spaces (#253)
  • Replace typeof macros like min, max, sq with template-based functions instead
    • Will fall back to the "classic" macros if in a non-c++ environment
  • Fix incorrect TWBR register in twi1.c
  • Add Wire timeout
    • Enable Wire timeout by adding -DWIRE_TIMEOUT as a compiler flag, or by uncommenting a line in Wire_timeout.h
  • Remove unnecessarytwi_masterBuffer from twi.c (#263)
  • Add Arduino Leonardo/Pro Micro as ISP to the list of supported programmers
  • Use "correct" lock/unlock byte values in boards.txt
    • Previously Avrdude tried to write 0's to reserved bits that's supposed to be 1's
  • Prepare for Avrdude 7.1
    • avrdude.conf updated to fully utilize the features and improvements Avrdude 7.1 brings over the current Avrdude 6.3

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
