bobtidey: Is the SYS 1.6 you provided the one modified for the community application? If so, I can’t find the modified table or any additional functions. It is very similar to the current “factory” SYS except for the 8M changes. In the fixed community app there is also something odd going on in the FFT function that may have to do with SYS. Without a debugger it is a bit hard to say.
The “Gabinator” application is completely different, and looks like new (cleaner) code. It should be easy for him to make the sector size a variable.
