looks as though some STM32 header files are missing from the Giga support

What version do you have of board ???

Hi @horace. The core_debug.h file is specific to the core of the 3rd party "STM32 MCU based boards" platform (AKA "STM32duino"):

https://github.com/stm32duino/Arduino_Core_STM32/blob/2.10.1/cores/arduino/core_debug.h

The "STM32_CAN" library is specifically written for use with that platform, and can not be used with the "Arduino Mbed OS Giga Boards" platform:

https://github.com/pazi88/STM32_CAN#can-bus-library-for-arduino-stm32

This library should support all STM32 MCUs that are also supported in stm32duino Arduino_Core_STM32

"STM32 header files" implies a header file from a universal STM32 toolchain component. That is not the case here. This is an arbitrary non-standard file present in a 3rd party Arduino core. There is no reason to expect it to be present in the core of other platforms.

thanks for the information!

looks as though there is no support for using the STM32 onboard CAN interface
although the Arduino GIGA R1 WiFi web page states

There are different levels of "support" for a capability. For example:

  • The Arduino company provides an official actively maintained library with comprehensive documentation, making it easy to use the capability in Arduino sketches.
  • There is a 3rd party Arduino library that facilitates the use of the capability in Arduino sketches.
  • The hardware has the capability, but there isn't an Arduino library to facilitate its use, meaning you must use lower level code.
  • The hardware does not have the capability.

When you see a capability listed in the specs of a hardware product, it should generally only be taken as a claim that the hardware has that capability, without implying any specific level of support by the libraries and documentation.
