First let me say that trying to figure out how to implement DaisyLink is probably going to give me a brain tumor… I promise if I ever get it working I’ll write up a simple explanation of how to do it.
My current question… From the module builder’s guide (pg 39-41) it shows that INIT-IN and INIT-OUT are two different signals that coordinate the activation of the pull-up resistors for the I2C lines. Since the Extender module has two sockets, I assumed that it was build with DaisyLink in mind. However, it seems that everything for all pins on the module are just straight through and therefore there’s no way to control independently the pull-ups for pin #3.
Am I misreading the specs for DaisyLink or will I need two Extender modules to implement one DaisyLink module? It seems that there should be 11 pads on the Extender - a 3a & a 3b.
