DIY LTCC or similar system for LT1s

I'll work on your code to move more work on precompiler...

Relative to my question in post #272, if the dwell tables can't be dynamically generated by precompiler directives - the idea crossed my mind of creating another conditional mode of operation to generate the initializers could be a better solution. That way the user could set the compiler directive and customize their dwell targets. Then when the mcu boots in this config mode the populate functions would spit out their customized tables to the uart as static initializers to be pasted directly into the source. That would eliminate the populate functions from being run at bootup in normal mode, shortening start time by 10ms or so, as well as alleviating the need to create yet another external spreadsheet tool to generate the tables.

If I don't hear from you I'm going to code toward that goal as it's a very simple change.

This is the coil trigger signal from a 2010 5.3L silverado, no open circuits. So technically, we only know that it pulls down to exactly 4V, not sure what open circuit voltage is, due to a lack of time at the end of a friday....so I didn't think to do so...damnit. This engine uses the barrel shaped coils like spfautsch used in his videos.

So there is no feedback on that signal line to worry about when it comes to this type of coil.
I will venture a guess that a 5V signal suffers a 1v-.8v semiconductor based voltage drop on one leg of a transistor tied to ground.
