Is it possible to connect more than one device on the same SPI?
SPI:
The master can work with slaves in two modes: with independent slaves or cooperative slaves.


With independent slaves I just need to select them with the uC's I/O
pins.
With cooperative slaves I need to "daisy-chain" them (I
won't be using this).




I2C:
It has a 2 line bus (clock and data) and I just need to connect them to Vdd and the master and slave devices.
