In the development process, i have not considered this stuiation(stack capes).I2C address changed just for interim use. But now, I have modified the source code to realize the function.
once you change the I2C address, It will not be used immediately. You should send another command to save it into flash and restart the capes automatically. It will load the new address to initialize I2C. For the details, i will tell you via email. Please kindly check the email. And if you have other good advices, please share me. :smiley:
