SPI is however not useable as a bus. You need a specific chip select pin line for every chip you communicate with. But yes I like SPI much better as well.

- CamperBob2 6y agoIt works as a bus when the chip manufacturer is nice enough to add a couple of address pins. Unfortunately not all that commonly done.
- rowanG077 6y agoI have never seen that actually. But also have never looked. I have used a binary decoder to achieve the same thing though.
