I fiddle with a digital potentiometer MCP4131 which communicates via the SPI protocol. I've seen several tutorials in which multiple SPI devices are connected to a common Slave Select line and the bits of information overflow from the first Slave device to the second, etc.
I wonder weather would be possible to connect two MCP4131 potentiometers with a common Slave Select line, due to the fact that they have a common MISO/MOSI pin.
So, shouldn't MISO/MOSI be in different pins, thus connect MISO of the first device to the MOSI of the second one?
I am a bit confused, so any thought would be appreciated. The following articles didn't help me understand much.
