Yes it writes to a file. It is not a temporary file, it is the config file. It automatically creates a backup of the lasy good config file upon a save. That way, if the computer crashes or hard power offs, while in the write state, the backup file can be restored.

Not sure what you mean by devices restart after the car turns on/off. The PIC works like this for the most part:

a) if there is a signal from the computer within a second or so, then it believes that the computer is on. Therefore pass the values it has to the outputs.

b) if no signal is received, it assumes the computer is off, and all the outputs go low.

So when the PIC is started, it makes all the outputs low, until a signal from the computer is received which contains the info it needs. Since you can power the PIC from anything between ~7v to 18v that means you can power the board from your cars unregulated voltage on a switched line to turn off the board completely when the car is off, or you can use a constant line. Either will work, and no advantage of one over the other.

It is all done through the program, but that just writes to an ASCII based file called "UserConfig.atom". You may open it in Notepad and do whatever you please, all manually, but I must warn you now as well as the warning in the top of the config file... It is a very unforgiving file. You miss a colon ":" and the entire thing might fail at worst, or overwrite what you just did with the backup file because the one you made has errors.

I DO NOT RECOMMEND MANUALLY EDITING THIS FILE!

The entire config is meant to be really TS friendly for changing everything on the fly, and taking away the need for a keyboard. I even made my own OSK for it.

Done
