-====== Hooking up Pixy to a Raspberry Pi ====== +====== Hooking up Pixy2 to a Raspberry Pi ======
- +
- +
-We're sorry, we're working on releasing the new version of libpixyusb. It is simpler to use, simpler to compile, and it is fully compatible with the Arduino API. Libpixyusb2 will be ready on or before June 29, 2018. +

-====== 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. +
