| ==Summary==
| |
| [[File:102424263.jpg|thumb|Prototyping]]
| |
| [[File:Jonty and sign.jpg|thumb|Installed]]
| |
| This is the board that hangs in the space.
| |
| | |
| It sends visual and audible notifications to the space, and also publishes notifications to the network: temperature, movement etc
| |
| | |
| Current version 0.2
| |
| | |
| ==Phases==
| |
| :*Phase 1: <strike>Allow messages to be displayed on the LED board from IRC.</strike>
| |
| :*Phase 2: <strike>Add sounds when the message changes.</strike>
| |
| :*Phase 3: Add strobe beacons.
| |
| :*Phase 4: Daemon the arduino and allow connection via MQTT, add idle messages.
| |
| | |
| | |
| Moved to separate project/arduino:
| |
| :<strike>*Phase 5: Add temperature, light level and PIR sensors.</strike>
| |
| :<strike>*Phase 6: Add i-wire, inc i-buttons.</strike>

| |
| * Scroll for messages longer than the screen
| |
| | |
| ===v0.2===
| |
| * Include full ascii support
| |
| * Add initText
| |
| * Remove update speed delay
| |
| | |
| ===v0.1===
| |
| * Initial proof of concept
| |
| * Limit to a-z A-Z and 0-9
| |
| | |
| ==Protocol Specification==
| |
| | |
| ===Sending a message===
| |
| Currently, messages are sent directly over serial.
| |
| | |
| They are upto 160 char's long, and can only be from regular ascii. The message is terminated with a line return.
| |
| | |
| '''This is a test msg\n'''
| |
| | |
| ===Proposed new protocol===
| |
| There are 2 types of message:
| |
| :* Idle - for rolling messages, i.e. temprature, currently playing song, number of irc users. Will keep last value till updated.
| |
| :* Alert - for one time shown messages, allows sounds
| |
| | |
| ====Idle====
| |
| The settings for idle messages are:
| |
| * Message slot [0-5] - (see list below for reserving a slot)
| |
| * Time sensitive? [0-1] - If you need to bump the idle message to be the next shown, i.e. currently playing song changes
| |
| * Message [up to 21 chars]
| |
| | |
| | |
| Examples:
| |
| (Substituting STX, ETB and EOT for their respective ascii chars.)
| |
| | |
| So to send, Temprature: 21.5, you would send:
| |
| | |
| '''STX'''1'''ETB'''0'''ETB'''Temprature: 21.5'''EOT'''
| |
| | |
| | |
| Or to send, Iron Maiden - Prowler, time sensitive:
| |
| | |
| '''STX'''2'''ETB'''1'''ETB'''Iron Maiden - Prowler'''EOT'''
| |
| | |
| | |
| ====Alert====
| |
| The settings for alert messages are:
| |
| * Message slot [A] - Denotes alerts from idle messages
| |
| * Blink [0-1] - Blink the display for more attention
| |
| * Sound [0-5] - Set off a sound, see list
| |
| * Display timeout - The length of time to display the message for
| |
| * Message [up to 21 chars]
| |
| | |
| | |
| Examples:
| |
| (Substituting STX, ETB and EOT for their respective ascii chars.)
| |
| | |
| To send, Ping: Solexious, with sound ping and blinking for 5 seconds:
| |
| | |
| '''STX'''A'''ETB'''1'''ETB'''1'''ETB'''5'''ETB'''Ping: Solexious'''EOT'''
| |
| | |
| ====Message slots====
| |
| * 0 - Current Number of users in #london-hack-space
| |
| * 1 - Temperature/Humidity
| |
| * 2 - Now Playing
| |
| * 3 - suggestion: info on tube delays, i.e. http://api.tubeupdates.com/?method=get.status where status != 'good service' (docs at http://tubeupdates.com/documentation/) --[[User:AndyE|AndyE]] 22:39, 12 November 2010 (UTC)

| ====Sounds====
| |
| * 0 - None

| ==Feature Requests==
| |
| | |
| * Dynamic font loading
| |
| * Individual pixel mapping
| |
| * <strike>Scrolling to allow for longer messages</strike>
| |
| * A fortune/motd feature - when the board has been unchanged for a while, display a random message from a file, e.g. 'clean up your own mess', 'shut the fire door when you leave' or 'do not leave the chuck key in the lathe'.
