A grblHAL driver for the Atmel SAM3X8E processor on a Arduino Due board.

This driver can be built with the Web Builder.

For local builds see the Wiki-page for compiling grblHAL for instructions for how to import the project, configure the driver and compile.

Available driver options can be found here.

Pin mappings for a selection of shields/boards can be found here.

This driver compiles and uploads from the Arduino IDE and is partially dependent on the Arduino framework.

Note: There is a hardcoded 10ms delay in the Arduino SAM core's CDC transmit codepath that causes very poor performance when using the native USB interface, see grblHAL forum discussion here. Commenting out the delay in your Arduino SAM core as shown in this issue / pr fixes the issue.
