This a custom designed module for the DS1307 Real Time Clock. The module comes fully assembled and pre-programmed with the current time (ok, so it’s * our current time - *MST). The included Lithium coin cell battery (CR1225 41mAh) will run the module for a minimum of 9 years (17 years typical) without external 5V power. The DS1307 RTC is accessed via the I2C protocol. We’ve written a test-bed to program the modules. This test-bed code should give you some insight on how to interface the module to any microcontroller using our example software I2C and BCD routines.

這是一個定制的模塊為DS1307實時時鐘。該模塊已經裝配完好,並與當前時間預編程(好吧,所以它的*我們的當前時間 - * MST)。所包含的鋰硬幣電池(CR1225 41mAh)將運行模塊最少9年 (17歲典型值),無需外部5V電源。的DS1307 RTC經由I2C協議訪問。我們已經寫了一個試驗台的模塊進行編程。該試驗台的代碼應該給你如何模塊接口使用我們的示例軟件I2C和BCD程序的任何微控制器上的一些見解。
