Final answer:
Wiring SPI devices in daisy chain is beneficial because it simplifies connections, requiring fewer GPIO pins by using a single chip select line for multiple devices.
Step-by-step explanation:
The major benefit of wiring SPI devices in daisy chain is that it allows multiple devices to be connected with minimal signal lines. Each device is connected to the next one in a series, with the output of one device being the input of the next.
This reduces the number of GPIO (General Purpose Input Output) pins required on the microcontroller, as only one chip select (CS) line is needed for all devices, rather than individual CS lines for each device.
Efficiency in connectivity and hardware simplicity are significant advantages of using the SPI daisy chain method. Through this configuration, data can be passed through each device in the chain, which allows for streamlined communication and potentially faster data transfer speeds when implemented correctly.
