I have an interface where it communicate in the same fashion as an SPI. Only issue is the normal SS lines is an ack.
Is blips just before data is transmitted to the master. I want to replicate that and I'm guessing I can to do that with the SS line.
I'm using the atmega32u4 and b0 is the SS line. When the SPI is enabled I can not drive that pin high or lo.
So what I'm wondering is. Is there any way to make the SS pull low for 2.31us and then go high? - Of course I'm not sure if the master is influencing the line or just reading it. If not I guess it would be ok to turn off the API do the blip and exit or maybe just use another pin.
