In theory, the number of slaves that the MCU can drive using the daisy chain configuration is

unlimited; in practice the maximum number of devices connected to the same SPI depends

on the clock skew.

The number of slaves also limits the communication speed because every time a byte has

to be transmitted to a device, the whole N slave chain has to be filled transmitting N - 1 extra

bytes.
