A grblHAL driver for the STM32F401xC, STM32F407xx, STM32F411xE and STM32F446xx ARM processors.
Loosely based on code from robomechs 6-AXIS-USBCNC-GRBL port, updated for STM32CubeIDE and the latest STM HAL drivers where appropriate.
See the Wiki-page for compiling grblHAL for instructions for how to import the project, configure the driver and compile.
2021-05-28: Added support for BTT SKR PRO
Available driver options can be found here.
Select the processor to build for from the build tool dropdown to build. The .bin created file can be found in the folder with the same name as the menu name when the build is completed.
A method for flashing the Nucleo F411 and Nucleo F446 is to drop the .bin file on the NODE_F4xxRE flash drive. Note that the file can be dragged from the IDE Project Explorer.
NOTE: Internal flash page for parameters is not at the end of the flash memory due to size restrictions. This means each firmware upgrade will erase any saved parameters.
If compiling for debugging, edit symbols in project properties C/C++ General > Paths and Symbols > Symbols to match your processor/board.
Remove symbols starting with STM32F4, starting with NUCLEO_F4 and HSE_VALUE. Then add symbols:
- Add
STM32F401xC.
- Add
STM32F407xx.
-
Add
STM32F411xE. -
If compiling for the Nucleo F411RE development board add
NUCLEO_F411.
-
Add
STM32F446xx. -
If compiling for the Nucleo F446RE development board add
NUCLEO_F446.
If the oscillator frequency is different from the default 25 MHz then add the symbol HSE_VALUE and set the value to the frequency in Hz. E.g. 8000000 for 8 Mhz.
