Set of useful classes for AVR platform. It's a part of my old AVR project (LCD display with a temperature sensor and a clock) for ATmega8. Note that this is not the complete library (a lot of hard-coded values in the implementation of classes), but it can help with writing an own implementation.
- Display: HD44780
- Real-time clock: DS3231 I2C
- Temperature sensor: DS18B20
- UART
- Timer
