'''This is a test msg\n''' | '''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 | |||
:* Alert - for one time shown messages, allows sounds | |||
====Idle==== | |||
To format an idle message for transmitting to the arduino, you need to know the following: | |||
* Idle message slot [1-5] - (see list below for reserving a slot) | |||
* Time sensitive? [1-0] - If you need to bump the idle message to be the next shown, i.e. currently playing song changes | |||
* Text of 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''' | |||
