  • MapleMini F103CB (Basic support, no USB)
• Fixed build failed on Windows if path contains space.
• Update c++ compilation standard to 2014 from 2011
• Moved from CMSIS 4.5.0 to 5.3.0
• HAL Drivers and CMSIS updated:
  • STM32F4xx HAL Drivers to v1.7.4

• Arduino compatibility:
  • Ax pin definition is now inline with Arduino style
  • Defining NUM_DIGITAL_PINS and NUM_ANALOG_INPUTS as literals
• Specify the ARM GCC version in platforms.txt (thanks @sandeepmistry)
• Add LoRa pins definition for B-L072Z-LRWAN1. LoRa Radio tested thanks arduino-LoRa library.
• Removed LwIP option file from the core (lwipopts.h)
  A default one is provided with STM32Ethernet library.
  Add a file named "STM32lwipopts.h" in the sketch folder could be used instead of the default config.
• Several clean and other fixes ...

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

Warning

Release versioning has been changed from date versioning to semantic one. See Release Versioning change

known issues

• I2C: Several issue raised around I2C and related to IT mode implementation, see #217

• Added setXXX methods to change used pins of Wire or SPI instances:
  Example to change pins used by Wire instance (by default use defined SDA/SCL ):

  Wire.setSDA(A4);
  Wire.setSCL(PC2);
  Wire.begin();
  

  Example to change pins used by SPI instance (by default use defined MISO/MOSI/SCK):

  SPI.setMOSI(22);
  SPI.setMISO(PA3);
  SPI.begin();
  

• Added recipe.hooks feature to override gcc options thanks a file named "build_opt.h" in the sketch directory.

• Allow to redefine core Exception handler

• Enhance DEBUG_UART feature (used by printf)

• Improve micros() accuracy using SysTick COUNTFLAG

• Improve SPI library code clarity

• Provide access to Low Layer (LL) drivers

• Fixed build issue when USART1 or USART2 is not defined

• Fixed L4 ADC read issue

• Fixed LED_BUILTIN for DISCO_L072CZ_LRWAN1

• Several clean and other fixes ...
