Able to run the first panel with the configuration mentioned. Need help with the code of the new multiplex mapper of Panel 2. Please suggest the solution

Actually the diagram I have made is of one single LED module. Not the panel configuration
Sorry, pixel mapper, not panel mapper. Still, look around that area of the code, the mapping code effectively does not know or care where the panel boundaries are. The Vmapper:Z code I wrote inverts all the pixels within a panel, inverting lines or whatever within a panel is ultimately similar
