PRU Projects

Users of TI processors with PRU-ICSS have created application for many different uses. A list of a few are shared below. For additional support resources, software and documentation visit the PRU-ICSS wiki.

LEDscape

Description: BeagleBone Black cape and firmware for driving a large number of WS281x LED strips.

Type: Code Library Documentation and example projects.

LDGraphy

Description: Laser direct lithography for printing PCBs.

Type: Code Library and example project.

DMX Lighting
Interacto

Description: A cape making BeagleBone interactive with a triple-axis accelerometer, gyroscope and magnetometer plus a 640 x 480/30 fps camera. All sensors are digital and communicate via I²C to the BeagleBone. The camera frames are captured using the PRU-ICSS. The sensors on this cape give hobbyists and students a starting point to easily build robots and flying drones.

Type: Project 1 Project 2 Code Library

Replicape: 3D Printer

Description: Replicape is a high end 3D-printer electronics package in the form of a Cape that can be placed on a BeagleBone Black. It has five high power stepper motors with cool running MosFets and it has been designed to fit in small spaces without active cooling. For a Replicape Daemon that processes G-code, see the Redeem Project

Geiger

Description: The Geiger Cape, created by Matt Ranostay, is a design that measures radiation counts from background and test sources by utilising multiple Geiger tubes. The cape can be used to detect low-level radiation, which is needed in certain industries such as security and medical.
