Device Drivers

A collection of MCAL (Microcontroller Abstraction Layer) modules and
ECUAL (Embedded Component Abstraction Layer) interfaces for a variety
of peripherals.
Originally written for AVR/ATmega328p and PIC16F887, the code is intended
for hobby and educational projects requiring direct access to hardware.

Features

• MCAL drivers for GPIO, I²C, USART, timers, ADC, interrupts, …
• ECUAL modules – ready‑to‑use interfaces for buttons, LCDs, OLEDs,
  ultrasonic sensors, Wi‑Fi modules, etc.
• Designed to be portable across AVR and PIC micros; adapt by swapping
  the mcal/* folder.

Getting started

1. Clone the repository:

   git clone https://github.com/your‑username/device-drivers.git
   cd device-drivers

2. Browse the code under lib/mcal/<your‑mcu> and lib/ecual.

3. Compile an example or integrate the drivers into your own project.
   (No build system included; use your preferred toolchain/IDE for AVR or PIC.)

Examples

Checkout the examples/ directory for small test programs such as
gpio.c demonstrating basic usage.

OLED driver

The OLED display implementation lives in lib/ecual/oled_display.
It includes source, fonts, images and even GIF routines.

Contributing

Feel free to submit issues or pull requests. Open‑source drivers are
always better with more hardware support and documentation!
