LPC176x grblHAL driver

A GrblHAL driver for NXP LPC1768 and LPC1769 processors.

Loosely based on the official grbl-LPC port.

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.

Update 2020-12-11:

  • Added initial board map file for Bigtreetech SKR V1.3 Turbo board.

Update 2020-11-21:

  • Added initial board map file for BTT SKR V1.4 Turbo board.
  • Added polling of limit switches, enabling hard limits is now possible.

A build option for creating a Firmware.bin file that can be used for programming via the Smoothieboard DFU-bootloader has been added to build configurations.
Select the BL_0x4000 configuration from the build tool dropdown to build, and programming can then be done via SD card transfer:
Config
Firmware.bin is found in the BL_0x4000 project folder after a successful build.

Update 2020-01-01:

  • Added board map file for Ramps 1.6 on Re-ARM board hacked for programming via Segger J-Link. Improved pin assignment handling and fixed some bugs. USB comms and SD card seems to be working ok for this board, however only limited testing done.

1 Each enabled reduces N_AXIS with one. Currently the board map file must be edited to enable ganged/auto squared axes.
2 I2C EEPROM (or FRAM) is optional and must be added externally. FRAM is recommended when the Odometer plugin is added to the build.
