Hi,
Can any one tell me how to interface Atxmega32A4 with DS1337 real time clock ic.
Multiple thin and narrow pieces of electrically conductive solidified material.
Look up “TWI” in the 32A4 datasheet; that’s what Atmel calls I2C. Connect SDA between the two chips, and SCL between the two chips. Add a pullup resistor to each. Connect the interrupt pins if you want to use them, but I would try to get things working without them first.
