Motion Fpga

This project builds a Motion FPGA used by processor to easily control motion devices. It is intended for use in projects such as:

• 3D Printers
• CnC Milling Machines
• General Robotics

Target Hardware

This project has targets for the following FPGAs:

• Lattice MachXO2-7000HE Breakout Board
• Lattice MachXO3D-9400HC Breakout Board

Overview

Numerous motion-control devices require I/O signals which can be cumbersome for a processor to manage directly. Instead this FPGA provides a simpler interface with the processor, and manage the I/O signals.

Common types of motion-control devices include:

• Digital Input (sensors, status, etc)
• Digital Output (enables, LEDs, etc)
• PWM Output (heaters, fans, etc)
• Stepper Drivers (motors)
• Quadrature Inputs (encoders)

The types of high-speed interfaces between a processor and the Motion FPGA include:

• SPI
• Virtual External Memory (Memory read/write)
• PCIe (Memory read/write)
