SPI
SPI (Serial Peripheral Interface Bus) er en synkron seriell databuss utviklet av Motorola på slutten av 1980-årene, først og fremst til bruk i innebygde systemer. Den er lisensfri,[1] og har etterhvert blitt industristandard, den brukes for eksempel av Secure Digital minnekort.
SPI arbeider i full dupleks, med en klokkelinje (SCLK, Serial Clock), en data ut linje (MOSI, Master Output, Slave Input) og en data inn linje (MISO, Master Input, Slave Output). For å kunne betjene mer enn en slave finnes det også en valglinje (SS, Slave Select).
