DS1307 clock module with buzzer

Overview

Compared to TB products, a typical DS1307 module brings out and pulls up the SQW pin; it also provides two larger pads, which can be used to solder a passive buzzer to the large pads, thereby utilizing the square wave output capability of the DS1307's SQW pin to make the buzzer sound.

Is anyone debugging SPI communication under S3C6400? Mine is acting strangely. I set it to receive mode and haven't connected the data source yet, but the SPI interrupt is constantly triggered. I don't know why? Is it interference? !
Is there anyone debugging SPI communication under S3C6400? Why is mine so strange? When it is set to receive mode and the data source is not connected, the SPI interrupt will be triggered continuously
