RAPcore Caravel Flow

https://rapcores.github.io/rapcores/

The Robotic Application Processing Core on the OpenMPW/Caravel Shuttle run sponsored by Google .

RAPcore is a project targeting FPGAs and ASIC devices for the next generation of motor and motion control applications. It is a peripheral that sits between firmwares and motors to free up processing on the microcontroller and greatly simplify the motor driver.

Gate Level Testing

Instructions for running gate-level validation:

Make sure submodules are correct:

git submodule init
git submodule update

Gate-level testing directory:

cd verilog/dv/caravel/rapcore/io_ports

make clean
make

Features

  • Onboard stepper motor commutator with microstepping
  • Fixed Point Step-Timing Algorithm
  • High-speed Quadrature Encoder Accumulator
  • High-Speed SPI Bus

Build Requirements

See INSTALL.md for local development instructions.
