I’m trying to get i2c getters working for W/ presently and having a hard time working through the correct sequence of commands. When TT sends a ‘get’ request to a module, that follower module must ACK the address, receive a byte (what data is being requested), transmit the data back to TT.
At present, I can successfully transmit data from W/ back to TT, but the byte that says what data to send isn’t available. I think I’m missing something conceptually about how the process is intended to work.
So now to the question: Where does the ii_process() function pointer get called?
It seems like it should be part of libavr32 but I couldn’t find any reference to it by name. I’m assuming it occurs via an interrupt, but I was surprised not to find it referred to anywhere by name. The point is that I want to see how the follower-side low-level driver responds when it receives a request for transmission. Any help directly on that would be great too, but even just pointing me to where that function is called would be a great help.
