Send I2C from xml file

That is something very specific. Without knowing anything, we can not answer that question.

I have heard of DSP boards with for example the ADAU1701 and Analog Devices has software to design the code. Most of those boards come with a USB to I2C interface to put the code into the DSP. I have also read somewhere that someone has made such a USB-to-I2C interface. But I don't know more about it.

On this forum, someone has for example a sensor that is not working. Then we can read the datasheet and check how it is wired, and maybe it will work or perhaps there is a other solution for the problem.
