This is a port of grblHAL for the STM32H7xx series of processors, originally based on the F7 driver from the official repository.

• Nucleo-H743ZI
• Nucleo-H723ZG
• WeAct MiniSTM32H7xx (H743 & H723)
• BTT SKR 3 EZ (H743 & H723)
• BTT Octopus Max EZ
• BTT Scylla

Builds for the above boards are supported through the upstream web app.

Local builds are supported from both STMCubeIDE and PlatformIO. Board specific settings have been included in the IDE configurations where possible - to avoid the need for code changes when building for different boards. (Please see the upstream Wiki-page compiling grblHAL for further instructions for how to import the project, configure the driver and compile).

PlatformIO builds for a number of configurations are run automatically as a GitHub Action on each push to the master branch. For convenience, the resulting firmwares are archived in the artifacts for each run, and can be found under the Actions tab on the GitHub repo (these files remain available for 90 days).
