This means that if you want to communicate with something via I2C, you can simply send the raw data to the I2C peripheral and it will control the pins to handle the specific timing requirements for this protocol. The RPI is supposed to be a leader on the bus and RPPal is fine for that but I know the RPI can also act as a follower sometimes, on a separate bus set on another set of GPIO. The Serial Peripheral Interface (SPI) bus was developed by Motorola to provide full-duplex synchronous serial communication between master and slave devices. Make something useful.
