This is for a simple program to take a analog voltage on one input pin and compare it to a table then send it out through a single wire to a dash for a temperature gauge. It uses a 7812.5 baud rate with 8bits ,no parity, and 1 stop bit. I may be able to fudge a little on the baud rate as i dont think the device is super picky on the rate at witch it come in at but 7812 is what the factory ECU used to communicate at. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=251099#m251112 Need assistance?
