Cosa is an object-oriented platform for Arduino. It replaces the Arduino and Wiring library with a large set of integrated classes that support the full range of AVR/ATmega/ATtiny internal hardware modules; all pin modes, Digital, and Analog Pins, External and Pin Change Interrupts, Analog Comparator, PWM, Watchdog, Timer0 (RTC), Timer1 (Servo/Tone/VWI), UART, USI, SPI, TWI and EEPROM.

Sketches using Cosa may be built with the Arduino IDE or with the built-in command line support.

More details are available in doc and install.

The API documentation is available :

• online
• Compressed for download.

The documentation contains a full hyperlinked description of all functions in Cosa together with UML graphs of the class hierarchy, include dependencies, and much more.

The provided documentation is generated with doxygen and may also be generated for users source code if the Cosa documentation style is adapted. See the Doxyfile for configuration of doxygen.

Cosa has built-in support for a large number of boards and clones/vendors. It also supports breadboards and custom-design boards with AVR MCUs.
