Open Pipe Kit - Developer Quick Start

Rolling the pipe by hand

Using the Pirateship disk image for Raspberry Pi (download the disk image that says "latest"), we can create a pipe that pulls temperature data from the CPU and pushes it to a CSV by adding two files to a USB Drive that we'll plug into our Raspberry Pi. Install the image onto an SD Card following the "WRITING AN IMAGE TO THE SD CARD" instructions on RaspberryPi.org.

Create an autorunonce.sh file and place the following code in that file. With this file in place, the next time your Raspberry Pi boots this will download the drivers that will pull and push data. Because the file is named autorunonce.sh, this file will only be run once and then be renamed to autoranonce.sh when it finishes.

#! /bin/bash

git clone https://github.com/openpipekit/opk-cli--rpi-cpu-temperature.git
git clone https://github.com/openpipekit/opk-cli--simple-csv.git

To use those drivers to pipe the Raspberry Pi's CPU temperature data to CSV, place on your USB Drive the following lines in a file named autorun.sh. Replace {{frequencyInSeconds}} with how often you would like to store data and replace {{fileName}} with the name of file where you would like output to go. This will run every time the Raspberry Pi boots but after the autorunonce.sh file.

#! /bin/bash

watch -n{{frequencyInSeconds}} './opk-cli--rpi-cpu-temperature/pull | opk-cli--simple-csv/push {{fileName}}'

Now plug your USB drive into your Raspberry Pi with an Internet connection. It will run the autorunonce.sh file to download the dependencies and then the autorun.sh from there on out. If your Raspberry Pi is not going to have Internet on it's first boot, you can place those dependencies on the USB Drive manually.

Roll the pipe using Yeobot, the robot generator

Load this code onto a USB drive even faster next time by utilizing a Yeobot Recipe that will download the code and prompt your for the string replacement. Yeobot requires Node.js.

# Install the yeobot cli
npm install -g yeobot
# Change directory to your USB Drive
cd /path-to-your-usb-drive
# Run the yeobot cli by feeding it a repository URL. It will clone the repo and prompt you for the string replacements.

Yeobot is a robot generator. See more recipes here.
