A small collection of C libraries for 8-bit PIC microcontrollers, built during high school projects.
This repo includes basic drivers for I²C communication, interrupts, LCD displays, PWM generation, and the MPU6050 IMU — all developed for the PIC18F877A.
The PIC18F877A is a popular 8-bit microcontroller from Microchip, widely used in educational and hobbyist projects. It features:
- 40 pins with multiple I/O ports
- Built-in USART, I²C, SPI modules
- PWM outputs
- 8-channel 10-bit ADC
- Rich interrupt system
It’s ideal for learning embedded systems programming and interfacing with basic sensors and peripherals.
Each module comes with .c and .h:
| Module | Description |
|---|---|
i2c |
Basic master-mode I²C implementation |
interrupt |
Setup and handlers for external/internal interrupts |
lcd |
16x2 character LCD control (4-bit mode) |
pwm |
PWM setup for controlling servos or motors |
mpu6050 |
Communication with the MPU6050 IMU sensor |
