Whether you're dealing with displays, memory modules, or sensors, SPI (Serial Peripheral Interface) is one of the most essential protocols in modern electronics. In this course, you’ll learn how to configure and implement SPI communication from scratch using PIC microcontrollers, so your devices talk smoothly and your projects work seamlessly.

Why SPI? Why PIC?

SPI is fast, full-duplex, and ideal for high-speed peripheral communication—but only if you understand how to structure your master-slave interactions correctly. This course walks you through real-world examples that help you:

• Wire and configure SPI-compatible devices
• Write clear C code to handle data exchange
• Handle timing, synchronization, and multi-device setup
• Troubleshoot signal issues and master-slave logic errors

What You’ll Learn

• The theory and electrical basics behind SPI
• Differences between SPI, I2C, and UART
• Master/slave configurations using PIC microcontrollers
• Writing embedded C code to initialize and manage SPI
• Reading/writing data to SPI-enabled peripherals (e.g., EEPROM, sensors, displays)
• Handling multi-device buses with chip select management
• Timing and clock polarity (CPOL/CPHA) explained with clarity
• Debugging communication issues using tools like logic analyzers

Real Projects You’ll Build

• SPI-controlled LED array with PIC
• Data logging using SPI EEPROM
• Display control via SPI OLED
• Multi-slave communication with priority control
• Real-time sensor interface using SPI
