I2C with its addressing scheme scales better. Two lines gets up to 128 devices (though also bus C limited).
I was under the impression that the number is 255 (256 with zero excluded).
The read/write bit reduces the address to 7 bits.
I agree.It depends on a number of slave select lines on the hardware. Example: If my SPI master has 4 slave select lines then we can connect 4 slaves normally.
