| ====== Hooking up Pixy2 to a Raspberry Pi ====== | ====== Hooking up Pixy2 to a Raspberry Pi ====== | ||
| - | |||
| - | ====== 1. Introduction ====== | ||
| - | |||
| - | The following procedure outlines the steps required to build the 'get blocks' example on a Raspberry Pi using the Raspberrian distribution. The 'get blocks' example is a simple program that demonstrates how to read blocks and send commands to the Pixy2 over USB like PixyMon. | ||
| - | |||
| - | You will need: | ||
| - | |||
| - | * SD Card withinstalled | ||
| - | * USB Hub with at least three ports | ||
| - | * Pixy2 updated to latest firmware | ||
| - | |||
| - | NOOBS is available from the Raspberry Pi website here: http://www.raspberrypi.org/downloads/ | ||
| - | |||
| - | |||
| - | ====== 2. Procedure ====== | ||
| - | |||
| - | |||
| - | ===== 2.1. Raspberry Pi Hardware Setup ===== | ||
| - | |||
| - | |||
| - | ==== 2.1.1. Connect your Raspberry Pi to the Internet ==== | ||
| - | |||
| - | Using an Ethernet cable, connect the Raspberry Pi to an internet source as shown below. | ||
| - | |||
| - | {{wiki:img:c915bad8138d82804e0f7f1360e4bbb54877be2f.jpg?400}} | ||
| - | |||
| - | |||
| - | ==== 2.1.2. Connect your Raspberry Pi to a video display ==== | ||
| - | |||
| - | Using an HDMI cable, connect the Raspberry Pi to a video display as shown below. | ||
| - | |||
| - | {{wiki:img:f3e7d4db3cdd88a0b0271ecee6465a8c3ec70a31.jpg?400}} | ||
| - | |||
| - | |||
| - | ==== 2.1.3. Connect Keyboard, Mouse, and Pixy2 to USB hub ==== | ||
| - | |||
| - | The Raspberry Pi only has two USB ports, so a hub is needed to connect Pixy2, a keyboard, and mouse simultaneously. Using the hub, connect your keyboard, mouse, and Pixy2 to the Raspberry Pi. | ||
