Hello,
I have a general understanding about how SPI works. I understand when your slave select pin goes low, communication begins. If you make pin 10 output high you can use another pin as the slave. Say, if you have another device on pin 4, you can switch between the two. Pulling each one low when you need it to communicate.
However, what happens if you are using another digital pin, say 6, used for a purpose other than SPI communication. If you change that to output low, will that interfere with the communication with the other devices using SPI(if they happen to be low at the same point)? If so, is there some way to isolate pins, not permitting them to interfere with the SPI communication of the other devices?
Thanks,
