Raspberry pi dashboard

This is what we did to setup a few dashboards at platanus

You'll need

Raspberry Pi
Dashing Service
Wifi stick (optional)

LIRC patch instruction/how-to for USB Infrared Toy from Dangerous Prototypes

This is a instruction to patch the usb infrared toy driver into lirc sources. Most of the work is done by Peter Kooiman

Requirements

Debian based OS (only tested on rapbian)
root privileges
USB Infrared Toy

Description

Dashing job to subscribe to MQTT messages.

MQTT is a lightweight publish/subscribe messaging transport. This job allows Dashing to subscribe to these messages and send them as events. There is no associated widget as the data can take any form - commonly numbers, but not necessarily. The script as laid out below sends events with value, current (the same contents) and last values so can be plugged directly into the Numbers or Meter widgets using the data-id in the dashboard file. The send_event could easily be modified if required.

Set up

Add to Gemfile:

	#!/usr/bin/env python

	import curses
	import curses.textpad
	import time

	stdscr = curses.initscr()

	#curses.noecho()
	#curses.echo()

	// Arduino serial-interface for controlling the ws2812 leds. The serial interface is based on the
	// Adalight protocol. The protocol is as follows:
	// [prefix][led count][checksum][red, green, blue]*
	// prefix := 'Ada'
	// led count := number of leds - 1 (uint16_t big endian)
	// checksum := led count high bit XOR led count low bit XOR 0x55 (uint8_t)
	// red, green, blue := channel intensity [0-255] (uint8_t)
	//
