...that gp13 was selected to use the level shifter board used, but then decided that gp13 must be toggled - or somehow play into it after not having success


Initially I wondered too what role should GP13 play? You only have a CLOCK and a DATA signal, so what's GP13 for? It is only acting as a supply for 3v3. I measured GP13 and it is set on HIGH = 3v3. So I connected my pullups to the 3v3 pin directly and it works fine.

And still, you may want to consider the possibility that the user does not want to shift up to 5v signals and provide a way to select the 'high side' voltage level with a jumper?


Yes, I am working on it, to allow this. Seems to be a good idea!
