		+	===Using Arduino with CAN Bus===
		+
		+	Perhaps the ''fastest'' way to get started with the CAN Bus is with an Arduino Shield. There's more than one way to lay out a board with the SPI based MCP2551 & MCP2515 chips.
		+	Access to a Microchip CAN BUS Analyzer tool is nice, but definitely not necessary. Each of these products has a different [[media:Db9-types.png\|pinout on the DB9 port]], but that's not really necessary anyway. If you want to connect to your car, then maybe you will care. We are interested in wheelchair hacking, so the shield with the screw terminals may win right off the bat.
		+
		+	[[File:IMG_20130408_234148.jpg\|thumb\|right\| The ''easiest'' way may be using the shield sold by sparkfun, which includes 2 LEDs, a little joystick, and some other goodies.]]

		+	=== More info ===
		+	Quote from the paper from the paper Schedulability Analysis of CAN based Systems with
		+	Precedence Constraints [http://www.can-cia.org/fileadmin/cia/files/icc/7/amaya.pdf]
		+
		+
		+	DXBus is a four wire communications system
		+	(two power lines and two data lines, CANL and
		+	CANH) with a maximum length of 15 meters
		+	and a transmission rate of 2/19 Mbits/s.
		+	Basically, DXBus uses CAN protocol with
		+	some extensions, i. e. special voltage values
		+	on the data lines are used for “emergency
		+	stops” or power up.
		+	CAN identifiers are assigned to modules and
		+	not to messages. As a result, 1 byte in the
		+	message data field must be used to indicate
		+	the message type, and up to 7 bytes for
		+	message data.
		+	During normal operation, DX modules
		+	communicate using Network Variables (NVs).
		+	NVs are transmitted periodically (during time
		+	slot), with period either 20ms (fast NV) or
		+	200ms (slow NV).
		+	A more detailed description of DXBus can be
		+	obtained from [10]. In this paper, we focus on
		+	the processes associated to DXSIR functions.
		+	DXSIR is a wheelchair with two driver wheels
