TI makes BeagleBone programming real-time

PRU Cape

Texas Instrument hopes to simplify the programming of the BeagleBone Black embedded computing board.

It has introduced the PRU Cape as a BeagleBone Black add-on board that gives designers access to a Programmable Real-Time Unit (PRU) core.

The PRU is a low-latency microcontroller subsystem integrated in the Sitara AM335x and AM437x family of devices.

The PRU core is optimised for deterministic, real-time processing, direct access to I/Os and ultra-low-latency requirements. It includes LEDs and push buttons for GPIO, audio, and a temp sensor.

The add-on board is compatible with both BeagleBone and BeagleBone Black boards.

There is also sample Linux software code.
