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...

• Fix I2C issues raised since IT mode introduction

• Add I2C Scanner examples thanks @Testato

• WString: add toDouble (Arduino compatibility)

• [U(S)ART] Allow to use defined PIN_SERIALx_RX and PIN_SERIALx_TX in variant.h if user instantiate a hardware Serial using peripheral name.
  Example:
  HardwareSerial mySerial(USART3);
  will use PIN_SERIAL3_RX and PIN_SERIAL3_TX if defined.

• Allow use of a custom startup file:
  Syntax in the board.txt:
  xxx.build.startup_file=-DCUSTOM_STARTUP_FILE

  Example to use a custom startup file for Nucleo_L476RG:
  Nucleo_64.menu.pnum.NUCLEO_L476RG.build.startup_file=-DCUSTOM_STARTUP_FILE
  Then add a "*.S" file in the "variant/NUCLEO_L476RG/" folder
  Important note: extension must be '.S' not '.s'

  CUSTOM_STARTUP_FILE could also be defined thanks the build_opt.h.
  CMSIS_STARTUP_FILE could now be overridden using the build_opt.h, ex:
  -DCMSIS_STARTUP_FILE=\"startup_stm32l476xx.s\"

• Remove SD core dependencies. STM32SD will be able to handle properly SD detect pin and FatFs options.
  SD_DETECT_PIN pin number definition could be added in variant.h

  Split stm32yyxx_ll.h file per feature (stm32yyxx_ll_*.h), this allow a better granularity and to include only the required LL header file instead of the full list.

• Add built-in IWatchdog library thanks @ghent360.

• Add debug(const char *format, ...) function

• Remove GSM built-in library

• Remove UART emulation

Plus some other small fixes: See 1.3.0...1.4.0
