如何调试I2C和RTC

我有一个基本的I2C交易与温度传感器工作。我禁用了所有的I2Cases，并从示例中引入了RTC计数器，这也是有效的。但是当我重新启用I2C调用时，它看起来像是在等待最后一个字节的传输（I2C。C的第951行）。我担心其中一个中断例程会导致I2C事务被搞乱，但我不知道该在哪里查找如何调试。我附上了我的项目。
我错过了一些基本的关于这些模块如何相互作用？
谢谢，

  I had a basic I2C transaction with a temperature sensor working.  I disabled all the I2C stuff and brought in the RTC counter from the example, and that was working as well.  But when I re-enabled the I2C calls, it looks like it's hanging forever waiting for the last byte to be transferred (line 951 of I2C.c).  I am worried that one of the interrupt routines is causing the I2C transaction to be messed up, but I am not sure where to look to find out how, or to debug.  I've attached my project.  
    Am I missing something fundamental about how these modules interact with one another?
    Thanks,
