Arduino Core for STM32 2.0.0

Important note:

The board package index has changed to better follow the package index specification. New link is:

https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json

Main changes

As the number of variants continues to grow and in order to ease navigation, they have been grouped in sub-folders per series.

To improve variants support and generic ones several enhancements/fixes has been done:

• Each variant is linked to its mcu/package
• All pins capabilities is possible without modifying the PeriperhalPins.c PinMap array. ALTx pin naming allows to use all alternative possibilities which use other Hardware peripheral instances.
• All remap pins are supported (F0/G0)
• All dual pad pins are supported (H7)
• Analog definition clean up
• Several fixes in existing variants

All generic variants are now automatically generated thanks the STM32_open_pin_data repository which provides all the information required for the pin configuration of products based on STM32 MCU. All the generic variants are generated in the variant folder, this means all the generic STM32 MCU are generated. Only the linker script and the clock config are missing. A board_entry.txt file is generated to ease board declaration.

Note that flash size used can be increased by 2k as now all pins are available in the PeripheralPins.c. To decrease it you can redefine the \ PinMap arrays at sketch level to only provide access to the used pins. See the Wiki custom pinmap array section.

Enhancements/improvements:

  As the number of variants continues to grow and in order to ease navigation,
  they have been grouped in sub-folders per STM32 series.
• Rename PinMap_PWM to PinMap_TIM
• Extend Arduino pin naming to the max possibilities (64)
• Clean up old way to define Ax pins definition
• Rework analog pin management. Use mask to ease analog pin management and ease alternative
  analog pins introduction.
• Add Alternate pins (ALTx) management
  The PinName mentioned Px_y_ALTz (described in the PeripheralPins.c/PinNames.h files)
  are alternative possibilities which use other HW peripheral instances.
  To access those alternative PinName name using a pin number can be performed like this:
  • PYn_ALTx
  • Ax | ALTx
  • Dx | ALTx
  • x | ALTx
• Change Ax constants to an enum
• Move genpinmap from Arduino_Tools repository and renamed stm32variant.py
• Allow use of a custom peripheral pins file
  Syntax in the board.txt:
  xxx.build.peripheral_pins=-DCUSTOM_PERIPHERAL_PINS
  Example to use a custom peripheral pins file for Nucleo_L476RG:
  Nucleo_64.menu.pnum.NUCLEO_L476RG.build.peripheral_pins=-DCUSTOM_PERIPHERAL_PINS
  Then add...
