Explore the spi protocol, a synchronous serial communication where the clock enables simultaneous data transfer between a master and a slave, widely used in Arduino boards and other devices.
Understand the SPI working principle: one master controls multiple slaves over four lines—clock, master out slave in, master in slave out, and per-slave select.
Explore the SPI library for PIC microcontrollers, detailing API initialize, API initialize advance, read, write, and set active functions to configure master mode, clock settings, and data transfer.
Design a SPI circuit in Proteus by selecting a PIC16F877A, adding a crystal, capacitors, and resistors, wiring power, and connecting SPI lines to an SPI debugger to visualize memory.
Program an SPI communication by configuring the simulator circuit, initializing the SPI protocol, and sending data with the SPI write function to an SPI device.
Explore Proteus software for electronic design automation by downloading the evaluation copy and installing the demo version to simulate sample designs and create schematics for printed circuit boards.
Discover mikroC pro for PIC, an IDE for PIC microcontrollers with libraries, debuggers, and examples. Learn how to download and install the free version to start building embedded applications.
Tired of confusing communication errors in your embedded systems?
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
