Double checked the programming of the Wabbits. Updated the Wabbits and documentation.
Turns out that the Wabbit documentation is not correct. Looking at the feedback provided states that pin #1 of J5 and J6 are the plus for the CLEAR feedback. This is true IF CV 49 is programmed to 1, the default is 0. Of course how you need to program CV 49 depends on the orientation of the Tortoise to the turnout being controlled. All documented in the Wabbit Feedback Wiring page.
Variable names "save1" and "_save1" are not the same. Finely found it though.
Got the Wabbit feedback working as I wanted. Still need to try and get the asynchronous interrupt driven status reporting to work.
Flushed out the commands for signal controls. Quick test of the LED the lights in the parking lot and made a semaphore servo move that was quickly plugged in for testing.
