An SPI less than one indicates that your project is running behind schedule.
What purposes do SPI serve?
Shift registers, sensors, and SD cards are just a few examples of the small peripherals that are routinely connected to microcontrollers via the Serial Peripheral Interface (SPI) interface bus. It uses separate clock and data lines as well as a choose line to choose the communication target.
How do SPI and I2C work?
SPI uses full duplex communication, whereas I2C only uses half duplex. I2C supports numerous masters and numerous slaves, but SPI only permits one master. I2C only has two wires, compared to four for SPI.
