CRAL: Cool Arduino Libraries Repository CRAL is a repository of useful libraries for the Arduino. The goal is to allow developers to easily add different circuits and integrated circuits to their Arduino project by abstracting all the business logic behind a class. Please contact dev@mlalonde.net to add new classes to the repository! http://svn.mlalonde.net/cral/ The configs directory holds various configuration files for the drivers Libraries DS1337: I2C Real time clock from Maxim IC DS1624: I2C Temperature sensor from Maxim IC DS1803: I2C Dual digital potentiometer from Maxim IC SPrint: Helps in printing strings stored in the program space to the serial port twiLCD: Driver for 4-bit HD44780 LCDs driven by a PCF8574 I2C I/O expander
