Populated board

Thought I would show what a fully populated board looks like when it's ready to be put into the box (minus wires).

Update to new code

I found out the other day that the newest version of code prevents Night Panel from working, or allowing you to use OpenSID.

I think the only difference is the 348 message, bit 2, being a 1 instead of a 5. I think when it's a 1, that is the highest priority, as if Night Panel were on (no gauges lit) & your coolant temp got too hot, your SID would light up & tell you. So I think it's probably better to leave this message bit higher & just deal with flashing SID txt for a few seconds.

Fabbed circuit boards!

Got my first run of fabbed circuit boards today; they look sick! I'll def be ordering more boards through OSHPark.com :)

updated code

Here's some updated code. This should fix the flickering of the SID text when switching to Aux mode. Also removed the 0x368 messages - Henrik informed me that they weren't needed. Not much else changed I don't think. This still includes the main CDC code as well as the extra code for 9-5's.
