Installing the Remora component

The Remora component is the interface between LinuxCNC and the controller board as well as being the LinuxCNC side of the step pulse generators. The Remora Linuxcnc install contains several seperate components. You can install them all, or only what you need. The components are found in the Remora Repository under

Remora/LinuxCNC/Components/ :

  • remora-spi.c : Raspberry Pi3/4/5 SPI driver for STM32 based boards

  • remora_lpc.c : Raspberry Pi4 SPI driver for LPC17xx based boards

  • remora-eth-3.0.c : Ethernet Driver for Remora Ethernet Firmware

  • PRUencoder.c : Remora Encoder driver

  • PIDcontroller.c : Remora PIDcontroller for temperature control

  • NVMPG.c : Driver for the NVEM serial pendant, the NVMPG

To install a Remora component:

  1. Open a terminal window , download the Remora repository and change to the Remora component directory

pi@raspberry:~ $ mkdir ~/linuxcnc
pi@raspberry:~ $ cd ~/linuxcnc
pi@raspberry:~ $ git clone https://github.com/scottalford75/Remora
pi@raspberry:~ $ cd Remora/LinuxCNC/Components

  1. Install the component using halcompile

pi@raspberry:~ $ sudo halcompile --install ./Remora-eth/remora-eth-3.0.c
pi@raspberry:~ $ sudo halcompile --install ./Remora-spi/remora-spi.c
pi@raspberry:~ $ sudo halcompile --install ./Remora/remora_lpc.c
pi@raspberry:~ $ sudo halcompile --install ./NVMPG/nvmpg.c
pi@raspberry:~ $ sudo halcompile --install ./PIDcontroller/PIDcontroller.c
pi@raspberry:~ $ sudo halcompile --install ./PRUencoder/PRUencoder.c
