Lab 7: SPI Communication

This lab allows students to explore communication using the Serial Peripheral Interface (SPI) bus. Students will learn about the basic theory behind SPI communication using a microcontroller (such as an Arduino Uno) as the SPI master and the Analog Discovery 2 as the SPI slave. Using LabVIEW, students will be able to visualize the slave select, clock, and MOSI lines of the SPI bus and learn how to extract the message from these lines. Advanced students can challenge themselves by modifying their code to encode and decode ASCII signals or adding a layer of encryption to protect their data from unwanted observers.
