• Enhancements/improvements

  • Use LL for GPIO access
  • Add digitalReadFast()/digitalWriteFast() API (use the PinName (PY_n) instead of the pin number (PYn))
  • Add digitalToggle()/digitalToggleFast()
  • Add USB CDC support across all supported series in FS/HS.
  • Update USB HID composite (keyboard and mouse)
  • Remove CapacitiveSensor built-in library (support added in official library)
  • Add preprocessing of linker script. This allow to use switch in ldscript.ld file.
    By default, add define for RAM and FLASH max size:
    -DLD_MAX_SIZE={upload.maximum_size} -DLD_MAX_DATA_SIZE={upload.maximum_data_size}
  • Rework Serial and USB menu:
    • Rename "Serial interface" to "U(S)ART support"
    • Rename "USB interface" to "USB support"
    • Add "USB speed" menu for USB speed: LS/FS/HS/HS in FS
    • Reword some descriptions

• Fixes

  • Fix SPI::setClockDivider implementation (#299)
  • Replace boolean with standard bool. boolean type now marked as deprecatedcd stm. See arduino/Arduino#4673.
  • [EEPROM] Wrong E2END definition (#396)
  • [dtostrf] Fix missing leading zeros in decimal part

Plus some other fixes: See 1.4.0...1.5.0

Several components libraries are available on stm32duino organization.
They are also available through the Arduino library manager. Search for STM32duino ;)
