core and version identification

[ag123]

is there a preprocessor define or a #define tag which i can tell between the cores (e.g. between official & libmaple) and version?
i think there is ARDUINO define, but i'd guess that's for the original Arduino?

it is a little unfortunate as APIs (e.g. SPI) between cores are at least a little different so some ifdefs are necessary

I think ARDUINO_ARCH_STM32F1 works for libmaple (roger's and steve's). Not sure about STM core.

Have you tried this? viewtopic.php?f=7&t=870

[ag123]

it seemed the official stm core could reserve the tag STM32DUINO or __STM32DUINO__ for its tag
not sure what is a failsafe way to do versions, e.g. so that we can have

Code: Select all

#if defined(STM32DUINO) && VERSION > 10000
 //do this
#else
  //do that
#endif

But literally i don't like it just that that's the way the world evolves


oh btw i saw that, maybe this would do

Code: Select all

ARDUINO_ARCH_STM32

Code: Select all

ARDUINO_ARCH_STM32

Right this is the official defintion to use for STM32 core.
For Libmaple F1 as mentionned by@GonzoG :

Code: Select all

ARDUINO_ARCH_STM32F1 

For Libmaple F4:

Code: Select all

ARDUINO_ARCH_STM32F4 

In fact this is specified by Arduino: https://arduino.github.io/arduino-cli/l ... hitectures

Code: Select all

-DARDUINO_ARCH_{build.arch}

thanks ! i'd use these symbols for now

oh what about version, does it matter?
i think for now we'd make do 'without versions' (too complicated)

glibc did something like this

in the compile/link environment, version is available from platform.txt

name=STM32F1 Boards (Arduino_STM32)
version=0.1.2

[fpiSTM]

For STM32 core since version 1.5.0 IIRW, the version are available this help to maintains some backward compatibility and check:
https://github.com/stm32duino/Arduino_C ... f.h#L5-L21

Code: Select all

/**
 * @brief STM32 core version number
 */
#define STM32_CORE_VERSION_MAJOR    (0x02U) /*!< [31:24] major version */
#define STM32_CORE_VERSION_MINOR    (0x00U) /*!< [23:16] minor version */
#define STM32_CORE_VERSION_PATCH    (0x00U) /*!< [15:8]  patch version */
/*
 * Extra label for development:
 * 0: official release
 * [1-9]: release candidate
 * F[0-9]: development
 */
#define STM32_CORE_VERSION_EXTRA    (0xF0U) /*!< [7:0]  extra version */
#define STM32_CORE_VERSION          ((STM32_CORE_VERSION_MAJOR << 24U)\
                                        |(STM32_CORE_VERSION_MINOR << 16U)\
                                        |(STM32_CORE_VERSION_PATCH << 8U )\
                                        |(STM32_CORE_VERSION_EXTRA))

You can use it like this:

Code: Select all

#if defined(STM32_CORE_VERSION) && (STM32_CORE_VERSION  > 0x01090000)
 // do some specific stuff
#endif
