@domdomgin The full source code is on my website linked in the description. The charlieplexing matrix is briefly described there too, but the exact mappings to drive vectors depend on how you lay out the wiring. I measured the final results and constructed the table you'll see in the source to match. Honestly I never traced out the exact circuit, I didn't need to, it is the same complete graph topology with arbitrary vertex numbering.

Thanks mate, I've just written up the construction details and the MCU source code. Rather inspired to build something larger and more colourful.
