This HAL is for STM32F103 boards used with libmaple/stm32duino Arduino core.
This HAL is in development and has not been tested with an actual printer.
The stm32 core needs a modification in the file util.h to avoid conflict with Marlin macros for Debug.
Since only 1 file needs change in the stm32duino core, it's preferable over making changes to Marlin.
After these lines: <> #else #define ASSERT_FAULT(exp) (void)((0)) #endif <>
Add the following 3 lines: <> #undef DEBUG_NONE #undef DEBUG_FAULT #undef DEBUG_ALL <>

Most up to date repository for this HAL:
https://github.com/victorpv/Marlin/tree/bugfix-2.0.x
PRs should be first sent to that fork, and once tested merged to Marlin bugfix-2.0.x branch.
