Final answer:
Serial RS232, SPI, and I2C are suitable communication protocols for communicating with multiple slave subsystems.
Step-by-step explanation:
If communication to multiple slave subsystems is required, Serial RS232, SPI, and I2C communication protocols would be suitable.
- Serial RS232: A serial communication protocol traditionally used for connecting peripherals such as modems and printers, which can also be used to communicate with multiple slave devices by implementing a bus system.
- SPI (Serial Peripheral Interface): A synchronous serial communication protocol that allows communication with multiple slave devices over short distances. It uses separate lines for data transmission and control signals.
- I2C (Inter-Integrated Circuit): A two-wire serial communication protocol that enables communication between multiple slave devices using a single bus. It supports multiple masters and a wide range of peripherals.
