 +====== Hooking up Pixy2 to a Raspberry Pi ======
  
  
-====== ​Hooking up Pixy to a Raspberry Pi ====== +Hooking up Pixy2 to your Raspberry Pi requires ​a software library called libpixyusb2. 
- +{{page>wiki:v2:building_the_libpixyusb_example_on_linux&​noheader&​noindent}}
- +
-====== 1. Introduction ====== +
- +
-The following procedure outlines the steps required to build the '​hello_pixy'​ example on a Raspberry Pi using the Raspberrian disribution. The '​hello\_pixy'​ example is a simple program that demonstrates how to read blocks and send commands to the Pixy over USB like PixyMon. +
- +
-You will need: +
- +
-  * SD Card with NOOBS 1.3.9 installed +
-  * USB Hub with at least three ports +
-  * Pixy updated to latest firmware (1.0.2) +
-  * libpixyusb version is 0.3 +
- +
-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 Pixy to USB hub ==== +
- +
-The Raspberry Pi only has two USB ports, so a hub is needed to connect Pixy, a keyboard, and mouse simultaneously. Using the hub, connect your keyboard, mouse, and Pixy to the Raspberry Pi. +
