PIC16F877A Embedded Lab Series

Collection of six hands-on embedded systems lab exercises for the PIC16F877A microcontroller, demonstrating timer interrupts, watchdog & sleep mode, ADC, serial communication, LCD & sensor interfacing, I²C, and CAN bus protocols.

📚 Overview

This monolithic repository groups six progressive labs, each in its own folder with complete source code, detailed explanations, and hardware setup instructions:

1. Timer Interrupts, Watchdog & Sleep Mode
2. Analog-to-Digital Conversion (ADC)
3. RS-232 Serial Communication & 7-Segment Display
4. LCD Control & DS1820 Temperature Sensor
5. I²C Bus & Real-Time Clock (PCF8583)
6. CAN Bus Communication & LCD Display

Each lab is designed to build practical skills in embedded-C and assembly on the PIC16F877A platform.
