This HAL is for STM32F103 boards used with libmaple/stm32duino Arduino core.
This HAL is in development. Currently has been tested in Malyan M200 (103CBT6), Chitu 3d (103ZET6), and custom boards(103VET6).
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 <>

PRs should only be sent to Marlin bugfix-2.0.x branch once tested in printing so not to introduce new bugs. For testing/dev, you can submit to the above branch
