Evoscan: documentation for bit fields?
I've been using EvoScan 2.6 with my 1994 Subaru Sport Sedan and LC-1 wideband with no problems -- once I figured out the correct parameter locations in the ECU.
There are several parameters which represent switches/relays in binary form. Example: 0x15A8 returns 179, which in binary is 1011 0011. These switches are IG AT !UD !RM xx !NT !PK FC. I know to extract the data out, one can use something like: x bit 128. The problem I'm having is the on/off logic for several of the binary switches is reversed. They return 1 when off and 0 when on.
Is there a logical NOT that I can use to reverse the data? I tried using: !(x bit 128) but it just spits out -1. What are all the variables/math one can use?
Side note: I've noticed when using the data.xml editor, some times it doesn't update the comment fields.
