This collection of driver classes provides a Hardware Abstraction Layer (HAL) library for use with AVR (ATTINY and ATMEGA) microcontrollers and is written in C++.
The drivers are intended to be used in projects based on AVR microcontrollers that are not developped using the arduino IDE and libraries. Despite that they might be used with Arduino hardware and can be compiled in Arduino IDE since it uses GCC compiler as well.
hal_avr_io.h - Digital IO driver.
hal_encoder.h - Rotary encoder driver.
hal_avr_i2c.h - i2c driver for microcontrollers with TWI hardware (ATMEGA) or USI hardware (ATTINY).
hal_avr_eeprom.h - Driver for the internal EEPROM of AVR microcontrollers.
hal_at24cxx_eeprom.h - Driver for EEPROM chips AT24C01, AT24C02, AT24C04, AT24C08, AT24C16, AT24C32, AT24C64.
Complete description of all classes and their public interface is provided in description.md.
Examples of usage of all drivers are given in an Arduino sketch hal_lib_avr_cpp.ino for easier demonstration. Example explanations are in the comments.
