Only to inform you that the fysetc_STM32F1 is not (anymore?) present in the platformio.ini config file of the official Marlin 2.0x github repository.
This mean, we have to replace the folder \Marlin\src\HAL**HAL_STM32F1** and replace it by the one provided by the Fysetc Github.
As these are from different versions, we don't know what could be the side effects to replace these folders.
Could you take a look on this to update the official Marlin 2.0x?
Or could you update the Wiki page of the Cheetah?
Thanks in advance!
