- | ====== Hooking up Pixy to a Beaglebone Black ====== | ||
- | |||
- | |||
- | ====== 1. Introduction ====== | ||
- | |||
- | The following procedure outlines steps to build the 'hello_pixy' example on a BeagleBone Black using the Debian Linux Distribution (Debian Image 2014-05-14). The 'hello_pixy' example is a simple program that demonstrates how to read blocks and send commands to the Pixy over USB like the PixyMon application. | ||
- | |||
- | You will need: | ||
- | |||
- | * BBB with Debian Linux Distribution installed to the eMMC | ||
- | * USB Hub with at least three ports | ||
- | * Pixy updated to the latest firmware (1.0.2) | ||
- | * libpixyusb version is 0.2 | ||
- | |||
- | The Debian Linux distribution for the BeagleBone Black is available from the BeagleBoard website here: http://beagleboard.org/latest-images/\\ | ||
- | A procedure for flashing the BeagleBone Black can be found here: https://learn.adafruit.com/beaglebone-black-installing-operating-systems/flashing-the-beaglebone-black | ||

- | ====== 2. Procedure ====== | ||
- | |||
- | |||
- | ===== 2.1. BeagleBone Black Hardware Setup ===== | ||
- | |||
- | |||
- | ==== 2.1.1. Using a USB hub, connect your keyboard, mouse, and Pixy to the BeagleBone Black. Using an Ethernet cable, connect your BeagleBone Black to the internet.
