Advanced (z, u etc) pixel mappers for adafruit active3 bonnet. In short: are any of the pixel mapper modes of this lib relevant to this three-port interface? That was not clear on a first read.
I have 3 chains of 4 64x32 panels. I want to double the height for 6 high, 4 wide using serpentine, z or U topologies. I’m currently using adafruit’s simple\_multilane\_mapper and trying to save grinding through the pixel map to create a custom one. It’s all working great, just the team says: Make it Bigger!!! TIA

Two words
“Remap Mapper”

yes, it’s in the documentation
